======================== Configuration Parameters ======================== Introduction ------------ Nextcloud uses ``config/config.php`` as its main configuration file. This file controls various fundamental aspects of server operations. It is typically modified as part of initial deployment, when troubleshooting, and when making adjustments to surrounding infrastructure. This is a required file for all Nextcloud deployments and thus it is critical for Nextcloud administrators to be familiar with managing it. This section of the *Administration Manual* documents how to adjust this essential file, certain special characteristics of the ``config/`` directory, and all of the supported parameters that can be specified in a ``config/config.php`` file. .. note:: While ``config/config.php`` is a required file, many Nextcloud or Nextcloud app settings are managed elsewhere and thus not included in it. These settings are typically managed via individual apps. Loading ------- Configuration files located in ``config/`` are parsed automatically when Nextcloud starts up. They are also checked for changes periodically (approximately every two seconds in a standard PHP environment running with default *OPcache* settings; approximately every sixty seconds in many pre-packaged Nextcloud installation methods). The ``config/config.php`` file may be supplemented by additional ``*.config.php`` files placed in the ``config/`` directory (if appropriately named and formatted). .. danger:: Be cautious when naming or creating backup copies of your active ``config/config.php``. If a backup is located within ``config/`` and is named ``(ANYTHING).config.php``, it will be loaded as part of your live configuration and override your ``config/config.php`` values! .. tip:: If your configuration changes don't seem to be taking effect, check: (a) your PHP opcache configuration; (b) for additional ``*.config.php`` files located in ``config/``; (c) the documentation for your Nextcloud installation method/package; (d) the output of ``occ config:list system``. Format ------ The short answer is that ``config/`` files are plain text files with some special formatting requirements for different types of parameters and values. This makes it extensible and easy for Nextcloud to interact with. It also makes it easy for administrators to view with any text viewer and from the command-line. Technically these configuration files are PHP files containing a special (to Nextcloud) PHP array called ``$CONFIG``. This array consists of various Nextcloud specific "key-value" pairs (in some cases arrays themselves). Each pair has the form ``key => value`` and is comma-separated. Types of Values ^^^^^^^^^^^^^^^ Strings: * ``"thisIsAnImportantValue"`` * Note: These must be either single or double quoted - i.e. ``"string"`` or ``'string'``. * Note: IP addresses are considered strings. * Examples: - ``'logo_url' => 'https://example.org',`` - ``'versions_retention_obligation' => 'auto, D',`` - ``'logtimezone' => 'Europe/Berlin',`` Boolean: * ``true`` or ``false`` * Note: These should **not** be surrounded by quote marks within the configuration file itself. * Examples: - ``'session_keepalive' => true,`` - ``'hide_login_form' => false,`` Numerical: * ``12`` * This includes both integers and floating point numbers. * Note: These should **not** be surrounded by quote marks within the configuration file itself. * Examples: - ``'loglevel' => 2,`` - ``'session_lifetime' => 60 * 60 * 24,`` Arrays of any of the above types: * ``[ 'value1', 'value2' ]`` * All value types (including other arrays) can be included in arrays. * Note: Only some parameters support array style values. * Examples: - ``'connectivity_check_domains' => [ 'www.nextcloud.com', 'www.eff.org', ],`` - ``'enabledPreviewProviders' => [ 'OC\Preview\BMP', 'OC\Preview\GIF', 'OC\Preview\JPEG', ],`` .. tip:: Nextcloud attempts to remedy some value type/formatting mistakes, but this is not foolproof. Use the correct formatting (for the type of value in question) to avoid unexpected results arising from values being cast in unexpected ways. Modifying --------- Parameters may be modified in a standard text editor (i.e. via the command-line or externally then re-uploaded). They may also, in most cases, be modified using the commands in the ``occ config:system:*`` namespace. .. tip:: Incorrectly formatted ``key => value`` entries (or incorrectly specified values) may not generate immediate errors or problems (such as parsing / syntax errors), but may still lead to unexpected and undesirable results. Review your fully parsed (by PHP) configuration by using the command ``occ config:list system`` and/or ``occ config:list system --private`` to identify anything unexpected. Defaults -------- Nextcloud creates a base ``config/config.php`` file at installation time containing the most essential parameters for operations. These values are a mixture of auto-generated and drawn from information provided by the administrator at installation time. The file ``config/config.sample.php`` lists all the parameters within Nextcloud that can be specified in ``config/`` files, along with example and default values for each. The content of that sample configuration file is included :ref:`below` for ease of reference and alongside additional context. .. tip:: Only add parameters to ``config/config.php`` that you wish to modify. .. danger:: Do not copy everything from ``config/config.sample.php`` into your own ``config/config.php``! Besides being unnecessary, it will break things and possibly even require re-installation. Multiple/Merged Configuration Files ----------------------------------- Nextcloud supports loading configuration parameters from multiple files. You can add arbitrary files ending with ``.config.php*`` (i.e. ``*.config.php``) in the ``config/`` directory. The values in these files take precedence over ``config/config.php``. This allows you to easily create and manage custom configurations, or to divide a large complex configuration file into a set of smaller files. These custom files are not overwritten by Nextcloud. For example, you could place your email server configuration in ``config/email.config.php`` and whatever parameters you specify in it will be merged with your ``config/config.php``. .. note:: The values in these additional configuration files **always** take precedence over ``config/config.php``. .. tip:: To view your fully merged configuration (i.e. incorporating all config files), use ``occ config:list system`` and/or ``occ config:list system --private``. .. danger:: Be cautious when naming or creating backup copies of your active ``config/config.php``. If a backup config file is located within ``config/`` and happens to be named ``(ANYTHING).config.php``, it will be loaded as part of your live configuration and override your ``config/config.php`` values! Examples -------- These are some examples of the content of typical ``config/config.php`` files immediately after a basic installation of Nextcloud. When you use SQLite as your Nextcloud database, your ``config.php`` looks like this after installation. The SQLite database is stored in your Nextcloud ``data/`` directory:: 'occ6f7365735', 'passwordsalt' => '2c5778476346786306303', 'trusted_domains' => array ( 0 => 'localhost', 1 => 'studio', ), 'datadirectory' => '/var/www/nextcloud/data', 'dbtype' => 'sqlite3', 'version' => '7.0.2.1', 'installed' => true, ); .. note:: SQLite is a simple, lightweight embedded database that is fine for testing and simple installations, but production environments you should use MySQL/MariaDB, Oracle, or PosgreSQL. This example is from a new Nextcloud installation using MariaDB:: 'oc8c0fd71e03', 'passwordsalt' => '515a13302a6b3950a9d0fdb970191a', 'trusted_domains' => array ( 0 => 'localhost', 1 => 'studio', 2 => '192.168.10.155' ), 'datadirectory' => '/var/www/nextcloud/data', 'dbtype' => 'mysql', 'version' => '7.0.2.1', 'dbname' => 'nextcloud', 'dbhost' => 'localhost', 'dbtableprefix' => 'oc_', 'dbuser' => 'oc_carla', 'dbpassword' => '67336bcdf7630dd80b2b81a413d07', 'installed' => true, ); .. The following section is auto-generated from .. https://github.com/nextcloud/server/blob/master/config/config.sample.php .. Do not edit this file; edit the source file in core .. DEFAULT_SECTION_START Default Parameters ------------------ These parameters are configured by the Nextcloud installer, and are required for your Nextcloud server to operate. instanceid ^^^^^^^^^^ :: 'instanceid' => '', This is a unique identifier for your Nextcloud installation, created automatically by the installer. This example is for documentation only, and you should never use it because it will not work. A valid ``instanceid`` is created when you install Nextcloud. serverid ^^^^^^^^ :: 'serverid' => -1, This is a unique identifier for your server. It is useful when your Nextcloud instance is using different PHP servers. Once it's set it shouldn't be changed. Value must be an integer, comprised between 0 and 1023. When config.php is shared between different servers, this value should be overriden with "NC_serverid=" on each server. Note that it must be overriden for CLI and for your webserver. Example for CLI: NC_serverid=42 occ config:list system passwordsalt ^^^^^^^^^^^^ :: 'passwordsalt' => '', The salt used to hash all passwords, auto-generated by the Nextcloud installer. (There are also per-user salts.) If you lose this salt, you lose all your passwords. This example is for documentation only, and you should never use it. .. deprecated:: 9.0.0 This salt is deprecated and only used for legacy-compatibility, developers should *NOT* use this value for anything nowadays. secret ^^^^^^ :: 'secret' => '', Secret used by Nextcloud for various purposes, e.g., to encrypt data. If you lose this string, there will be data corruption. trusted_domains ^^^^^^^^^^^^^^^ :: 'trusted_domains' => [ 'demo.example.org', 'otherdomain.example.org', '10.111.112.113', '[2001:db8::1]' ], Your list of trusted domains that users can log into. Specifying trusted domains prevents host header poisoning. Do not remove this, as it performs necessary security checks. You can specify: - The exact hostname of your host or virtual host, e.g. ``demo.example.org``. - The exact hostname with permitted port, e.g. ``demo.example.org:443``. This disallows all other ports on this host - Use ``*`` as a wildcard, e.g., ``ubos-raspberry-pi*.local`` will allow ``ubos-raspberry-pi.local`` and ``ubos-raspberry-pi-2.local`` - The IP address with or without permitted port, e.g. ``[2001:db8::1]:8080`` Using TLS certificates where ``commonName=`` is deprecated cookie_domain ^^^^^^^^^^^^^ :: 'cookie_domain' => '', The validity domain for cookies, for example ``''`` (cookies will be sent only the domain that defined it, e.g. ``'demo.example.org'``), ``'demo.example.org'`` (cookies will be valid for the domain and all subdomains), ... Defaults to ``''`` (safe option) datadirectory ^^^^^^^^^^^^^ :: 'datadirectory' => '/var/www/nextcloud/data', Where user files are stored. The SQLite database is also stored here, when you use SQLite. Default to ``data/`` in the Nextcloud directory. version ^^^^^^^ :: 'version' => '', The current version number of your Nextcloud installation. This is set up during installation and update, so you shouldn't need to change it. dbtype ^^^^^^ :: 'dbtype' => 'sqlite3', Identifies the database used with this installation. See also config option ``supportedDatabases`` Available: - sqlite3 (SQLite3) - mysql (MySQL/MariaDB) - pgsql (PostgreSQL) Defaults to ``sqlite3`` dbhost ^^^^^^ :: 'dbhost' => '', Your host server name, for example ``localhost``, ``hostname``, ``hostname.example.com``, or the IP address. To specify a port, use ``hostname:####``; for IPv6 addresses, use the URI notation ``[ip]:port``. To specify a Unix socket, use ``localhost:/path/to/directory/containing/socket`` or ``:/path/to/directory/containing/socket``, e.g., ``localhost:/run/postgresql/``. dbname ^^^^^^ :: 'dbname' => 'nextcloud', The name of the Nextcloud database, which is set during installation. You should not need to change this. dbuser ^^^^^^ :: 'dbuser' => '', The user that Nextcloud uses to write to the database. This must be unique across Nextcloud instances using the same SQL database. This is set up during installation, so you shouldn't need to change it. dbpassword ^^^^^^^^^^ :: 'dbpassword' => '', The password for the database user. This is set up during installation, so you shouldn't need to change it. dbtableprefix ^^^^^^^^^^^^^ :: 'dbtableprefix' => 'oc_', Prefix for the Nextcloud tables in the database. Default to ``oc_`` dbpersistent ^^^^^^^^^^^^ :: 'dbpersistent' => '', Enable persistent connections to the database. This setting uses the ``persistent`` option from Doctrine DBAL, which in turn uses the PDO::ATTR_PERSISTENT option from the PDO driver. dbreplica ^^^^^^^^^ :: 'dbreplica' => [ ['user' => 'nextcloud', 'password' => 'password1', 'host' => 'replica1', 'dbname' => ''], ['user' => 'nextcloud', 'password' => 'password2', 'host' => 'replica2', 'dbname' => ''], ], Specify read-only replicas to be used by Nextcloud when querying the database db.log_request_id ^^^^^^^^^^^^^^^^^ :: 'db.log_request_id' => false, Add request ID to the database query in a comment. This can be enabled to assist in mapping database logs to Nextcloud logs. installed ^^^^^^^^^ :: 'installed' => false, Indicates whether the Nextcloud instance was installed successfully; ``true`` indicates a successful installation, and ``false`` indicates an unsuccessful installation. Defaults to ``false`` .. DEFAULT_SECTION_END .. Generated content above. Don't change this. .. _config-php-sample: .. Generated content below. Don't change this. .. ALL_OTHER_SECTIONS_START User Experience --------------- These optional parameters control some aspects of the user interface. Default values, where present, are shown. default_language ^^^^^^^^^^^^^^^^ :: 'default_language' => 'en', This sets the default language on your Nextcloud server, using ISO_639-1 language codes such as ``en`` for English, ``de`` for German, and ``fr`` for French. The default_language parameter is only used when the browser does not send any language, and the user hasn’t configured their own language preferences. Nextcloud has two distinguished language codes for German, ``de`` and ``de_DE``. ``de`` is used for informal German and ``de_DE`` for formal German. By setting this value to ``de_DE``, you can enforce the formal version of German unless the user has chosen something different explicitly. Defaults to ``en`` force_language ^^^^^^^^^^^^^^ :: 'force_language' => 'en', With this setting, a language can be forced for all users. If a language is forced, the users are also unable to change their language in the personal settings. If users shall be unable to change their language, but users have different languages, this value can be set to ``true`` instead of a language code. Defaults to ``false`` default_locale ^^^^^^^^^^^^^^ :: 'default_locale' => 'en_US', This sets the default locale on your Nextcloud server, using ISO_639 language codes such as ``en`` for English, ``de`` for German, and ``fr`` for French, and ISO-3166 country codes such as ``GB``, ``US``, ``CA``, as defined in RFC 5646. It overrides automatic locale detection on public pages like login or shared items. User's locale preferences configured under "personal -> locale" override this setting after they have logged in. Defaults to ``en`` reduce_to_languages ^^^^^^^^^^^^^^^^^^^ :: 'reduce_to_languages' => [], With this setting, it is possible to reduce the languages available in the language chooser. The languages have to be set as array values using ISO_639-1 language codes such as ``en`` for English, ``de`` for German, etc. For example: Set to ``['de', 'fr']`` to only allow German and French languages. default_phone_region ^^^^^^^^^^^^^^^^^^^^ :: 'default_phone_region' => 'GB', This sets the default region for phone numbers on your Nextcloud server, using ISO 3166-1 country codes such as ``DE`` for Germany, ``FR`` for France, … It is required to allow inserting phone numbers in the user profiles starting without the country code (e.g., +49 for Germany). No default value! force_locale ^^^^^^^^^^^^ :: 'force_locale' => 'en_US', With this setting, a locale can be forced for all users. If a locale is forced, the users are also unable to change their locale in the personal settings. If users shall be unable to change their locale, but users have different languages, this value can be set to ``true`` instead of a locale code. Defaults to ``false`` default_timezone ^^^^^^^^^^^^^^^^ :: 'default_timezone' => 'Europe/Berlin', This sets the default timezone on your Nextcloud server, using IANA identifiers like ``Europe/Berlin`` or ``Pacific/Auckland``. The default timezone parameter is only used when the timezone of the user cannot be determined. Defaults to ``UTC`` knowledgebaseenabled ^^^^^^^^^^^^^^^^^^^^ :: 'knowledgebaseenabled' => true, ``true`` enables the Help menu item in the user menu (top right of the Nextcloud Web interface). ``false`` removes the Help item. knowledgebase.embedded ^^^^^^^^^^^^^^^^^^^^^^ :: 'knowledgebase.embedded' => false, ``true`` embeds the documentation in an iframe inside Nextcloud. ``false`` only shows buttons to the online documentation. allow_user_to_change_display_name ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'allow_user_to_change_display_name' => true, ``true`` allows users to change their display names (on their Personal pages), and ``false`` prevents them from changing their display names. skeletondirectory ^^^^^^^^^^^^^^^^^ :: 'skeletondirectory' => '/path/to/nextcloud/core/skeleton', The directory where the skeleton files are located. These files will be copied to the data directory of new users. Set empty string to not copy any skeleton files. If unset and templatedirectory is an empty string, shipped templates will be used to create a template directory for the user. ``{lang}`` can be used as a placeholder for the language of the user. If the directory does not exist, it falls back to non-dialect (from ``de_DE`` to ``de``). If that does not exist either, it falls back to ``default`` Defaults to ``core/skeleton`` in the Nextcloud directory. templatedirectory ^^^^^^^^^^^^^^^^^ :: 'templatedirectory' => '/path/to/nextcloud/templates', The directory where the template files are located. These files will be copied to the template directory of new users. Set empty string to not copy any template files. ``{lang}`` can be used as a placeholder for the language of the user. If the directory does not exist, it falls back to non-dialect (from ``de_DE`` to ``de``). If that does not exist either, it falls back to ``default`` To disable creating a template directory, set both skeletondirectory and templatedirectory to empty strings. User session ------------ remember_login_cookie_lifetime ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'remember_login_cookie_lifetime' => 60 * 60 * 24 * 15, Lifetime of the remember login cookie. This should be larger than the session_lifetime. If it is set to 0, remember me is disabled. Defaults to ``60*60*24*15`` seconds (15 days) session_lifetime ^^^^^^^^^^^^^^^^ :: 'session_lifetime' => 60 * 60 * 24, The lifetime of a session after inactivity. The maximum possible time is limited by the ``session.gc_maxlifetime`` php.ini setting which would overwrite this option if it is less than the value in the ``config.php`` Defaults to ``60*60*24`` seconds (24 hours) davstorage.request_timeout ^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'davstorage.request_timeout' => 30, The timeout in seconds for requests to servers made by the DAV component (e.g., needed for federated shares). carddav_sync_request_timeout ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'carddav_sync_request_timeout' => 30, The timeout in seconds for synchronizing address books, e.g., federated system address books (as run by ``occ federation:sync-addressbooks``). Defaults to ``30`` seconds carddav_sync_request_truncation ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'carddav_sync_request_truncation' => 2500, The limit applied to the synchronization report request, e.g. federated system address books (as run by ``occ federation:sync-addressbooks``). session_relaxed_expiry ^^^^^^^^^^^^^^^^^^^^^^ :: 'session_relaxed_expiry' => false, ``true`` enables a relaxed session timeout, where the session timeout would no longer be handled by Nextcloud but by either the PHP garbage collection or the expiration of potential other session backends like Redis. This may lead to sessions being available for longer than what ``session_lifetime`` uses but comes with performance benefits as sessions are no longer a locking operation for concurrent requests. session_keepalive ^^^^^^^^^^^^^^^^^ :: 'session_keepalive' => true, Enable or disable session keep-alive when a user is logged in to the Web UI. Enabling this sends a "heartbeat" to the server to keep it from timing out. Defaults to ``true`` auto_logout ^^^^^^^^^^^ :: 'auto_logout' => false, Enable or disable the automatic logout after session_lifetime, even if session keepalive is enabled. This will make sure that an inactive browser will log itself out even if requests to the server might extend the session lifetime. .. note:: The logout is handled on the client side. This is not a way to limit the duration of potentially compromised sessions. Defaults to ``false`` token_auth_enforced ^^^^^^^^^^^^^^^^^^^ :: 'token_auth_enforced' => false, Enforce token authentication for clients, which blocks requests using the user password for enhanced security. Users need to generate tokens in personal settings which can be used as passwords on their clients. Defaults to ``false`` token_auth_activity_update ^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'token_auth_activity_update' => 60, The interval at which token activity should be updated. Increasing this value means that the last activity on the security page gets more outdated. Tokens are still checked every 5 minutes for validity max value: 300 Defaults to ``60`` auth.bruteforce.protection.enabled ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'auth.bruteforce.protection.enabled' => true, Whether the brute force protection shipped with Nextcloud should be enabled or not. .. warning:: Disabling this is discouraged for security reasons. Defaults to ``true`` auth.bruteforce.protection.force.database ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'auth.bruteforce.protection.force.database' => false, Whether the brute force protection should write into the database even when a memory cache is available Using the database is most likely worse for performance, but makes investigating issues a lot easier as it's possible to look directly at the table to see all logged remote addresses and actions. Defaults to ``false`` auth.bruteforce.protection.testing ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'auth.bruteforce.protection.testing' => false, Whether the brute force protection shipped with Nextcloud should be set to testing mode. In testing mode, brute force attempts are still recorded, but the requests do not sleep/wait for the specified time. They will still abort with "429 Too Many Requests" when the maximum delay is reached. Enabling this is discouraged for security reasons and should only be done for debugging and on CI when running tests. Defaults to ``false`` auth.bruteforce.max-attempts ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'auth.bruteforce.max-attempts' => 10, Brute force protection: maximum number of attempts before blocking When more than max-attempts login requests are sent to Nextcloud, requests will abort with "429 Too Many Requests". For security reasons, change it only if you know what you are doing. Defaults to ``10`` ratelimit.protection.enabled ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'ratelimit.protection.enabled' => true, Whether the rate limit protection shipped with Nextcloud should be enabled or not. .. warning:: Disabling this is discouraged for security reasons. Defaults to ``true`` ratelimit_overwrite ^^^^^^^^^^^^^^^^^^^ :: 'ratelimit_overwrite' => [ 'profile.profilepage.index' => [ 'user' => ['limit' => 300, 'period' => 3600], 'anon' => ['limit' => 1, 'period' => 300], ] ], Overwrite the individual rate limit for a specific route From time to time it can be necessary to extend the rate limit of a specific route, depending on your usage pattern or when you script some actions. Instead of completely disabling the rate limit or excluding an IP address from the rate limit, the following config allows to overwrite the rate limit duration and period. The first level key is the name of the route. You can find the route name from a URL using the ``occ router:list`` command of your server. You can also specify different limits for logged-in users with the ``user`` key and not-logged-in users with the ``anon`` key. However, if there is no specific ``user`` limit, the ``anon`` limit is also applied for logged-in users. Defaults to empty array ``[]`` security.ipv6_normalized_subnet_size ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'security.ipv6_normalized_subnet_size' => 56, Size of subnet used to normalize IPv6 For Brute Force Protection and Rate Limiting, IPv6 addresses are truncated using subnet size. It defaults to /56, but you can set it between /32 and /64 Defaults to ``56`` auth.webauthn.enabled ^^^^^^^^^^^^^^^^^^^^^ :: 'auth.webauthn.enabled' => true, By default, WebAuthn is available, but it can be explicitly disabled by admins auth.storeCryptedPassword ^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'auth.storeCryptedPassword' => true, Whether encrypted passwords should be stored in the database The passwords are only decrypted using the login token stored uniquely in the clients and allow connecting to external storages, autoconfiguring mail accounts in the mail app, and periodically checking if the password is still valid. This might be desirable to disable this functionality when using one-time passwords or when having a password policy enforcing long passwords (> 300 characters). By default, the passwords are stored encrypted in the database. .. warning:: If disabled, password changes on the user backend (e.g., on LDAP) no longer log connected clients out automatically. Users can still disconnect the clients by deleting the app token from the security settings. hide_login_form ^^^^^^^^^^^^^^^ :: 'hide_login_form' => false, By default, the login form is always available. There are cases (SSO) where an admin wants to avoid users entering their credentials to the system if the SSO app is unavailable. This will show an error. But the direct login still works with adding ``?direct=1`` lost_password_link ^^^^^^^^^^^^^^^^^^ :: 'lost_password_link' => 'https://example.org/link/to/password/reset', If your user backend does not allow password resets (e.g., when it's a read-only user backend like LDAP), you can specify a custom link, where the user is redirected to, when clicking the "Reset password" link after a failed login attempt. In case you do not want to provide any link, replace the URL with ``'disabled'`` logo_url ^^^^^^^^ :: 'logo_url' => 'https://example.org', URL to use as target for the logo link in the header (top-left logo) Defaults to the base URL of your Nextcloud instance Mail Parameters --------------- These configure the email settings for Nextcloud notifications and password resets. mail_domain ^^^^^^^^^^^ :: 'mail_domain' => 'example.com', The return address that you want to appear on emails sent by the Nextcloud server, for example ``nc-admin@example.com``, substituting your own domain, of course. mail_from_address ^^^^^^^^^^^^^^^^^ :: 'mail_from_address' => 'nextcloud', FROM address that overrides the built-in ``sharing-noreply`` and ``lostpassword-noreply`` FROM addresses. Defaults to different FROM addresses depending on the feature. mail_smtpdebug ^^^^^^^^^^^^^^ :: 'mail_smtpdebug' => false, Enable SMTP class debugging. .. note:: ``loglevel`` will likely need to be adjusted too. See docs: https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/email_configuration.html#enabling-debug-mode Defaults to ``false`` mail_smtpmode ^^^^^^^^^^^^^ :: 'mail_smtpmode' => 'smtp', Which mode to use for sending mail: ``sendmail``, ``smtp``, ``qmail``, or ``null``. If you are using local or remote SMTP, set this to ``smtp``. For the ``sendmail`` option, you need an installed and working email system on the server, with ``/usr/sbin/sendmail`` installed on your Unix system. For ``qmail``, the binary is /var/qmail/bin/sendmail, and it must be installed on your Unix system. Use the string ``null`` to send no mails (disable mail delivery). This can be useful if mails should be sent via APIs and rendering messages is not necessary. Defaults to ``smtp`` mail_smtphost ^^^^^^^^^^^^^ :: 'mail_smtphost' => '127.0.0.1', This depends on ``mail_smtpmode``. Specify the IP address of your mail server host. This may contain multiple hosts separated by a semicolon. If you need to specify the port number, append it to the IP address separated by a colon, like this: ``127.0.0.1:24``. Defaults to ``127.0.0.1`` mail_smtpport ^^^^^^^^^^^^^ :: 'mail_smtpport' => 25, This depends on ``mail_smtpmode``. Specify the port for sending mail. Defaults to ``25`` mail_smtptimeout ^^^^^^^^^^^^^^^^ :: 'mail_smtptimeout' => 10, This depends on ``mail_smtpmode``. This sets the SMTP server timeout, in seconds. You may need to increase this if you are running an anti-malware or spam scanner. Defaults to ``10`` seconds mail_smtpsecure ^^^^^^^^^^^^^^^ :: 'mail_smtpsecure' => '', This depends on ``mail_smtpmode``. Specify ``ssl`` when you are using SSL/TLS. Any other value will be ignored. If the server advertises STARTTLS capabilities, they might be used, but they cannot be enforced by this config option. Defaults to ``''`` (empty string) mail_smtpauth ^^^^^^^^^^^^^ :: 'mail_smtpauth' => false, This depends on ``mail_smtpmode``. Change this to ``true`` if your mail server requires authentication. Defaults to ``false`` mail_smtpname ^^^^^^^^^^^^^ :: 'mail_smtpname' => '', This depends on ``mail_smtpauth``. Specify the username for authenticating to the SMTP server. Defaults to ``''`` (empty string) mail_smtppassword ^^^^^^^^^^^^^^^^^ :: 'mail_smtppassword' => '', This depends on ``mail_smtpauth``. Specify the password for authenticating to the SMTP server. Default to ``''`` (empty string) mail_template_class ^^^^^^^^^^^^^^^^^^^ :: 'mail_template_class' => '\OC\Mail\EMailTemplate', Replaces the default mail template layout. This can be utilized if the options to modify the mail texts with the theming app are not enough. The class must extend ``\OC\Mail\EMailTemplate`` mail_send_plaintext_only ^^^^^^^^^^^^^^^^^^^^^^^^ :: 'mail_send_plaintext_only' => false, Email will be sent by default with an HTML and a plain text body. This option allows sending only plain text emails. mail_smtpstreamoptions ^^^^^^^^^^^^^^^^^^^^^^ :: 'mail_smtpstreamoptions' => [], This depends on ``mail_smtpmode``. Array of additional streams options that will be passed to underlying Swift mailer implementation. Defaults to an empty array. mail_sendmailmode ^^^^^^^^^^^^^^^^^ :: 'mail_sendmailmode' => 'smtp', Which mode is used for sendmail/qmail: ``smtp`` or ``pipe``. For ``smtp``, the sendmail binary is started with the parameter ``-bs``: - Use the SMTP protocol on standard input and output. For ``pipe``, the binary is started with the parameters ``-t``: - Read message from STDIN and extract recipients. Defaults to ``smtp`` Proxy Configurations -------------------- overwritehost ^^^^^^^^^^^^^ :: 'overwritehost' => '', The automatic hostname detection of Nextcloud can fail in certain reverse proxy and CLI/cron situations. This option allows you to manually override the automatic detection; for example, ``www.example.com``, or specify the port ``www.example.com:8080``. overwriteprotocol ^^^^^^^^^^^^^^^^^ :: 'overwriteprotocol' => '', When generating URLs, Nextcloud attempts to detect whether the server is accessed via ``https`` or ``http``. However, if Nextcloud is behind a proxy and the proxy handles the ``https`` calls, Nextcloud would not know that ``ssl`` is in use, which would result in incorrect URLs being generated. Valid values are ``http`` and ``https``. overwritewebroot ^^^^^^^^^^^^^^^^ :: 'overwritewebroot' => '', Nextcloud attempts to detect the webroot for generating URLs automatically. For example, if ``www.example.com/nextcloud`` is the URL pointing to the Nextcloud instance, the webroot is ``/nextcloud``. When proxies are in use, it may be difficult for Nextcloud to detect this parameter, resulting in invalid URLs. overwritecondaddr ^^^^^^^^^^^^^^^^^ :: 'overwritecondaddr' => '', This option allows you to define a manual override condition as a regular expression for the remote IP address. For example, defining a range of IP addresses starting with ``10.0.0.`` and ending with 1 to 3: ``^10\.0\.0\.[1-3]$`` Defaults to ``''`` (empty string) overwrite.cli.url ^^^^^^^^^^^^^^^^^ :: 'overwrite.cli.url' => '', Use this configuration parameter to specify the base URL for any URLs which are generated within Nextcloud using any kind of command line tools (cron or occ). The value should contain the full base URL: ``https://www.example.com/nextcloud`` Please make sure to set the value to the URL that your users mainly use to access this Nextcloud. Otherwise, there might be problems with the URL generation via cron. Defaults to ``''`` (empty string) htaccess.RewriteBase ^^^^^^^^^^^^^^^^^^^^ :: 'htaccess.RewriteBase' => '/', To have clean URLs without ``/index.php``, this parameter needs to be configured. This parameter will be written as "RewriteBase" on update and installation of Nextcloud to your ``.htaccess`` file. While this value is often simply the URL path of the Nextcloud installation, it cannot be set automatically properly in every scenario and needs thus some manual configuration. In a standard Apache setup, this usually equals the folder that Nextcloud is accessible at. So if Nextcloud is accessible via ``https://mycloud.org/nextcloud``, the correct value would most likely be ``/nextcloud``. If Nextcloud is running under ``https://mycloud.org/``, then it would be ``/``. Note that the above rule is not valid in every case, as there are some rare setup cases where this may not apply. However, to avoid any update problems, this configuration value is explicitly opt-in. After setting this value, run ``occ maintenance:update:htaccess``. Now, when the following conditions are met, Nextcloud URLs won't contain ``index.php``: - ``mod_rewrite`` is installed - ``mod_env`` is installed Defaults to ``''`` (empty string) htaccess.IgnoreFrontController ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'htaccess.IgnoreFrontController' => false, For server setups that don't have ``mod_env`` enabled or restricted (e.g., suEXEC), this parameter has to be set to true and will assume mod_rewrite. Please check if ``mod_rewrite`` is active and functional before setting this parameter, and you updated your .htaccess with ``occ maintenance:update:htaccess``. Otherwise, your Nextcloud installation might not be reachable any more. For example, try accessing resources by leaving out ``index.php`` in the URL. proxy ^^^^^ :: 'proxy' => '', The URL of your proxy server, for example, ``proxy.example.com:8081``. .. note:: Guzzle (the HTTP library used by Nextcloud) reads the environment variables ``HTTP_PROXY`` (only for CLI requests), ``HTTPS_PROXY``, and ``NO_PROXY`` by default. If you configure a proxy with Nextcloud, any default configuration by Guzzle is overwritten. Make sure to set ``proxyexclude`` accordingly if necessary. Defaults to ``''`` (empty string) proxyuserpwd ^^^^^^^^^^^^ :: 'proxyuserpwd' => '', The optional authentication for the proxy to use to connect to the internet. The format is: ``username:password``. Defaults to ``''`` (empty string) proxyexclude ^^^^^^^^^^^^ :: 'proxyexclude' => [], List of hostnames that should not be proxied to. For example: ``['.mit.edu', 'foo.com']``. Hint: Use something like ``explode(',', getenv('NO_PROXY'))`` to sync this value with the global ``NO_PROXY`` option. Defaults to empty array. allow_local_remote_servers ^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'allow_local_remote_servers' => true, Allow remote servers with local addresses, e.g., in federated shares, webcal services, and more Defaults to ``false`` Deleted Items (trash bin) ------------------------- These parameters control the Deleted files app. trashbin_retention_obligation ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'trashbin_retention_obligation' => 'auto', If the trash bin app is enabled (default), this setting defines the policy for when files and folders in the trash bin will be permanently deleted. If the user quota limit is exceeded due to deleted files in the trash bin, retention settings will be ignored and files will be cleaned up until the quota requirements are met. The app allows for two settings, a minimum time for trash bin retention, and a maximum time for trash bin retention. Minimum time is the number of days a file will be kept, after which it *may be* deleted. A file may be deleted after the minimum number of days has expired if space is needed. The file will not be deleted if space is not needed. Whether "space is needed" depends on whether a user quota is defined or not: * If no user quota is defined, the available space on the Nextcloud data partition sets the limit for the trashbin (issues: see https://github.com/nextcloud/server/issues/28451). * If a user quota is defined, 50% of the user's remaining quota space sets the limit for the trashbin. Maximum time is the number of days at which it is *guaranteed to be* deleted. There is no further dependency on the available space. Both minimum and maximum times can be set together to explicitly define file and folder deletion. For migration purposes, this setting is installed initially set to "auto", which is equivalent to the default setting in Nextcloud. Available values (D1 and D2 are configurable numbers): * ``auto`` | Default setting. Keeps files and folders in the trash bin for at least **30** days. | Then, **if space is needed**, deletes trashed files anytime after that. * ``D1, auto`` | Keeps files and folders in the trash bin for at least **D1** days. | Then, **if space is needed**, deletes trashed files anytime after that. * ``auto, D2`` | **If space is needed**, deletes trashed files anytime. | After **D2** days, delete all trashed files automatically * ``D1, D2`` | Keeps files and folders in the trash bin for at least **D1** days. | Then, after **D2** days, delete all trashed files automatically. * ``disabled`` | Trash bin auto clean is disabled, files and folders will be kept forever. Defaults to ``auto`` File versions ------------- These parameters control the Versions app. versions_retention_obligation ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'versions_retention_obligation' => 'auto', If the versions app is enabled (default), this setting defines the policy for when versions will be permanently deleted. The app allows for two settings, a minimum time for version retention, and a maximum time for version retention. Minimum time is the number of days a version will be kept, after which it may be deleted. Maximum time is the number of days at which it is guaranteed to be deleted. Both minimum and maximum times can be set together to explicitly define version deletion. For migration purposes, this setting is installed initially set to "auto", which is equivalent to the default setting in Nextcloud. Available values: * ``auto`` default setting. Automatically expire versions according to expire rules. Please refer to :doc:`../configuration_files/file_versioning` for more information. * ``D, auto`` keep versions at least for D days, apply expiration rules to all versions that are older than D days * ``auto, D`` delete all versions that are older than D days automatically, delete other versions according to expire rules * ``D1, D2`` keep versions for at least D1 days and delete when exceeds D2 days * ``disabled`` versions auto clean disabled, versions will be kept forever Defaults to ``auto`` Nextcloud Verifications ----------------------- Nextcloud performs several verification checks. There are two options, ``true`` and ``false``. appcodechecker ^^^^^^^^^^^^^^ :: 'appcodechecker' => true, Checks an app before install whether it uses private APIs instead of the proper public APIs. If this is set to true, it will only allow installing or enabling apps that pass this check. Defaults to ``false`` updatechecker ^^^^^^^^^^^^^ :: 'updatechecker' => true, Check if Nextcloud is up-to-date and shows a notification if a new version is available. It sends current version, PHP version, installation and last update time, and release channel to the updater server which responds with the latest available version based on those metrics. Defaults to ``true`` updater.server.url ^^^^^^^^^^^^^^^^^^ :: 'updater.server.url' => 'https://updates.nextcloud.com/updater_server/', URL that Nextcloud should use to look for updates Defaults to ``https://updates.nextcloud.com/updater_server/`` updater.release.channel ^^^^^^^^^^^^^^^^^^^^^^^ :: 'updater.release.channel' => 'stable', The channel that Nextcloud should use to look for updates Supported values: - ``daily`` - ``beta`` - ``stable`` has_internet_connection ^^^^^^^^^^^^^^^^^^^^^^^ :: 'has_internet_connection' => true, Is Nextcloud connected to the Internet or running in a closed network? Defaults to ``true`` connectivity_check_domains ^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'connectivity_check_domains' => [ 'https://www.nextcloud.com', 'https://www.startpage.com', 'https://www.eff.org', 'https://www.edri.org' ], Which domains to request to determine the availability of an Internet connection. If none of these hosts are reachable, the administration panel will show a warning. Set to an empty list to not do any such checks (warning will still be shown). If no protocol is provided, both http and https will be tested. For example, ``http://www.nextcloud.com`` and ``https://www.nextcloud.com`` will be tested for ``www.nextcloud.com`` If a protocol is provided, only this one will be tested. Defaults to the following domains: - https://www.nextcloud.com - https://www.startpage.com - https://www.eff.org - https://www.edri.org check_for_working_wellknown_setup ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'check_for_working_wellknown_setup' => true, Allows Nextcloud to verify a working .well-known URL redirects. This is done by attempting to make a request from JS to ``https://example.tld/.well-known/caldav/`` Defaults to ``true`` check_for_working_htaccess ^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'check_for_working_htaccess' => true, This is a crucial security check on Apache servers that should always be set to ``true``. This verifies that the ``.htaccess`` file is writable and works. If it is not, then any options controlled by ``.htaccess``, such as large file uploads, will not work. It also runs checks on the ``data/`` directory, which verifies that it can't be accessed directly through the Web server. Defaults to ``true`` check_data_directory_permissions ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'check_data_directory_permissions' => true, In rare setups (e.g., on OpenShift or Docker on Windows), the permissions check might block the installation while the underlying system offers no means to "correct" the permissions. In this case, set the value to false. In regular cases, if issues with permissions are encountered, they should be adjusted accordingly. Changing the flag is discouraged. Defaults to ``true`` config_is_read_only ^^^^^^^^^^^^^^^^^^^ :: 'config_is_read_only' => false, In certain environments, it is desired to have a read-only configuration file. When this switch is set to ``true``, writing to the config file will be forbidden. Therefore, it will not be possible to configure all options via the Web interface. Furthermore, when updating Nextcloud, it is required to make the configuration file writable again and to set this switch to ``false`` for the update process. Defaults to ``false`` Logging ------- log_type ^^^^^^^^ :: 'log_type' => 'file', This parameter determines where the Nextcloud logs are sent. - ``file``: the logs are written to file ``nextcloud.log`` in the default Nextcloud data directory. The log file can be changed with parameter ``logfile``. - ``syslog``: the logs are sent to the system log. This requires a syslog daemon to be active. - ``errorlog``: the logs are sent to the PHP ``error_log`` function. - ``systemd``: the logs are sent to the Systemd journal. This requires a system that runs Systemd and the Systemd journal. The PHP extension ``systemd`` must be installed and active. Defaults to ``file`` log_type_audit ^^^^^^^^^^^^^^ :: 'log_type_audit' => 'file', This parameter determines where the audit logs are sent. See ``log_type`` for more information. Defaults to ``file`` logfile ^^^^^^^ :: 'logfile' => '/var/log/nextcloud.log', Name of the file to which the Nextcloud logs are written if parameter ``log_type`` is set to ``file``. Defaults to ``[datadirectory]/nextcloud.log`` logfile_audit ^^^^^^^^^^^^^ :: 'logfile_audit' => '/var/log/audit.log', Name of the file to which the audit logs are written if parameter ``log_type`` is set to ``file``. Defaults to ``[datadirectory]/audit.log`` logfilemode ^^^^^^^^^^^ :: 'logfilemode' => 0640, Log file mode for the Nextcloud logging type in octal notation. Defaults to ``0640`` (writable by user, readable by group). loglevel ^^^^^^^^ :: 'loglevel' => 2, Loglevel to start logging at. Valid values are: - ``0`` = Debug - ``1`` = Info - ``2`` = Warning - ``3`` = Error - ``4`` = Fatal. Defaults to ``2`` (Warning) loglevel_frontend ^^^^^^^^^^^^^^^^^ :: 'loglevel_frontend' => 2, Loglevel used by the frontend to start logging at. The same values as for ``loglevel`` can be used. If not set, it defaults to the value configured for ``loglevel`` or Warning if that is not set either. Defaults to ``2`` loglevel_dirty_database_queries ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'loglevel_dirty_database_queries' => 0, Loglevel used by the dirty database query detection. Useful to identify potential database bugs in production. Set this to loglevel or higher to see dirty queries in the logs. Defaults to ``0`` (debug) syslog_tag ^^^^^^^^^^ :: 'syslog_tag' => 'Nextcloud', If you maintain different instances and aggregate the logs, you may want to distinguish between them. ``syslog_tag`` can be set per instance with a unique ID. Only available if ``log_type`` is set to ``syslog`` or ``systemd``. The default value is ``Nextcloud``. syslog_tag_audit ^^^^^^^^^^^^^^^^ :: 'syslog_tag_audit' => 'Nextcloud', If you maintain different instances and aggregate the logs, you may want to distinguish between them. ``syslog_tag_audit`` can be set per instance with a unique ID. Only available if ``log_type`` is set to ``syslog`` or ``systemd``. The default value is the value of ``syslog_tag``. log.condition ^^^^^^^^^^^^^ :: 'log.condition' => [ 'shared_secret' => '57b58edb6637fe3059b3595cf9c41b9', 'users' => ['sample-user'], 'apps' => ['files'], 'matches' => [ [ 'shared_secret' => '57b58edb6637fe3059b3595cf9c41b9', 'users' => ['sample-user'], 'apps' => ['files'], 'loglevel' => 1, 'message' => 'contains substring' ], ], ], Log condition for log level increase based on conditions. Once one of these conditions is met, the required log level is set to debug. This allows debugging specific requests, users, or apps Supported conditions: - ``shared_secret``: if a request parameter with the name `log_secret` is set to this value, the condition is met - ``users``: if the current request is done by one of the specified users, this condition is met - ``apps``: if the log message is invoked by one of the specified apps, this condition is met - ``matches``: if all the conditions inside a group match, this condition is met. This allows logging only entries to an app by a few users. Defaults to an empty array. log.backtrace ^^^^^^^^^^^^^ :: 'log.backtrace' => false, Enables logging a backtrace with each log line. Normally, only Exceptions carry backtrace information, which are logged automatically. This switch turns them on for any log message. Enabling this option will lead to increased log data size. Defaults to ``false``. logdateformat ^^^^^^^^^^^^^ :: 'logdateformat' => 'F d, Y H:i:s', This uses PHP.date formatting; see https://www.php.net/manual/en/function.date.php Defaults to ISO 8601 ``2005-08-15T15:52:01+00:00``, see ``\DateTime::ATOM`` https://www.php.net/manual/en/class.datetimeinterface.php#datetimeinterface.constants.atom logtimezone ^^^^^^^^^^^ :: 'logtimezone' => 'Europe/Berlin', The timezone for logfiles. See https://www.php.net/manual/en/timezones.php Defaults to ``UTC`` log_query ^^^^^^^^^ :: 'log_query' => false, Append all database queries and parameters to the log file. Use this only for debugging, as your logfile will become huge. log_rotate_size ^^^^^^^^^^^^^^^ :: 'log_rotate_size' => 100 * 1024 * 1024, Enables log rotation and limits the total size of logfiles. Set it to 0 for no rotation. Specify a size in bytes, for example, 104857600 (100 megabytes = 100 * 1024 * 1024 bytes). A new logfile is created with a new name when the old logfile reaches your limit. If a rotated log file is already present, it will be overwritten. Defaults to 100 MB profiler ^^^^^^^^ :: 'profiler' => false, Enable built-in profiler. Helpful when trying to debug performance issues. Note that this has a performance impact and shouldn't be enabled on production. profiling.request ^^^^^^^^^^^^^^^^^ :: 'profiling.request' => false, Enable profiling for individual requests if profiling single requests is enabled or the secret is passed. This requires the excimer extension to be installed. Be careful with this, as it can generate a lot of data. The profile data will be stored as a JSON file in the profiling.path directory that can be analyzed with speedscope. Defaults to ``false`` profiling.request.rate ^^^^^^^^^^^^^^^^^^^^^^ :: 'profiling.request.rate' => 0.001, The rate at which profiling data is collected for individual requests. A lower value means more data points but higher overhead. Defaults to ``0.001`` profiling.secret ^^^^^^^^^^^^^^^^ :: 'profiling.secret' => '', A secret token that can be passed via ?profile_secret= to enable profiling for a specific request. This allows profiling specific requests in production without enabling it globally. No default value. profiling.sample ^^^^^^^^^^^^^^^^ :: 'profiling.sample' => false, Enable sampling-based profiling. This collects profiling data periodically rather than per-request. This requires the excimer extension to be installed. Be careful with this, as it can generate a lot of data. The profile data will be stored as a plain text file in the profiling.path directory that can be analyzed with speedscope. Defaults to ``false`` profiling.sample.rate ^^^^^^^^^^^^^^^^^^^^^ :: 'profiling.sample.rate' => 1, The rate at which sampling profiling data is collected in seconds. A lower value means more frequent samples but higher overhead. Defaults to ``1`` profiling.sample.rotation ^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'profiling.sample.rotation' => 60, How often (in minutes) the sample log files are rotated. Defaults to ``60`` profiling.path ^^^^^^^^^^^^^^ :: 'profiling.path' => '/tmp', The directory where profiling data is stored. Note that this directory must be writable by the web server user and will not be cleaned up automatically. Alternate Code Locations ------------------------ Some Nextcloud code may be stored in alternate locations. customclient_desktop ^^^^^^^^^^^^^^^^^^^^ :: 'customclient_desktop' => 'https://nextcloud.com/install/#install-clients', 'customclient_android' => 'https://play.google.com/store/apps/details?id=com.nextcloud.client', 'customclient_ios' => 'https://itunes.apple.com/us/app/nextcloud/id1125420102?mt=8', 'customclient_ios_appid' => '1125420102', 'customclient_fdroid' => 'https://f-droid.org/packages/com.nextcloud.client/', This section is for configuring the download links for Nextcloud clients, as seen in the first-run wizard and on Personal pages. Defaults to: - Desktop client: ``https://nextcloud.com/install/#install-clients`` - Android client: ``https://play.google.com/store/apps/details?id=com.nextcloud.client`` - iOS client: ``https://itunes.apple.com/us/app/nextcloud/id1125420102?mt=8`` - iOS client app ID: ``1125420102`` - F-Droid client: ``https://f-droid.org/packages/com.nextcloud.client/`` Activity -------- Options for the activity app. activity_expire_days ^^^^^^^^^^^^^^^^^^^^ :: 'activity_expire_days' => 365, Retention of activities. A daily cron job deletes all activities for all users which are older than the number of days specified here. Defaults to ``365`` activity_use_cached_mountpoints ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'activity_use_cached_mountpoints' => false, Activities in Team Folders and External Storages. By default, activities in team folders or external storages are only generated for the current user. This is due to a limitations in current implementations. This config flag makes activities in group folders and external storages work like in normal shares (when set to ``true``). .. warning:: Enabling this comes with some CRITICAL trade-offs: - If team folder "Advanced Permissions" (ACLs) are used, activities do not respect the permissions and therefore all users see all activities, even for files and directories they do not have access to. - Users who had access to a team folder, share, or external storage can see activities in their stream and emails that happen after they are removed until they log in again. - Users who are newly added to a team folder, share, or external storage cannot see activities in their stream or emails that happen after they are added until they log in again. Defaults to ``false`` Apps ---- Options for the Apps folder, Apps store, and App code checker. defaultapp ^^^^^^^^^^ :: 'defaultapp' => 'dashboard,files', Set the default app to open on login. The entry IDs can be retrieved from the Navigations OCS API endpoint: https://docs.nextcloud.com/server/latest/developer_manual/_static/openapi.html#/operations/core-navigation-get-apps-navigation. You can use a comma-separated list of app names, so if the first app is not enabled for a user, then Nextcloud will try the second one, and so on. If no enabled apps are found, it defaults to the dashboard app. Defaults to ``dashboard,files`` appstoreenabled ^^^^^^^^^^^^^^^ :: 'appstoreenabled' => true, When enabled, admins may install apps from the Nextcloud app store. Defaults to ``true`` appstoreurl ^^^^^^^^^^^ :: 'appstoreurl' => 'https://apps.nextcloud.com/api/v1', Enables the installation of apps from a self-hosted apps store. Requires that at least one of the configured apps directories is writable. Defaults to ``https://apps.nextcloud.com/api/v1`` appsallowlist ^^^^^^^^^^^^^ :: 'appsallowlist' => [], Filters allowed installable apps from the appstore. Empty array will prevent all apps from the store to be found. apps_paths ^^^^^^^^^^ :: 'apps_paths' => [ [ 'path' => '/var/www/nextcloud/apps', 'url' => '/apps', 'writable' => true, ], ], Use the ``apps_paths`` parameter to set the location of the Apps directory, which should be scanned for available apps, and where user-specific apps should be installed from the Apps store. The ``path`` defines the absolute file system path to the app folder. The key ``url`` defines the HTTP Web path to that folder, starting from the Nextcloud webroot. The key ``writable`` indicates if a Web server can write files to that folder. Previews -------- Nextcloud supports generating previews for various file types, such as images, audio files, and text files. These options control enabling and disabling previews, and thumbnail size. enable_previews ^^^^^^^^^^^^^^^ :: 'enable_previews' => true, By default, Nextcloud can generate previews for the following filetypes: - Image files - Text documents Valid values are ``true``, to enable previews, or ``false``, to disable previews Defaults to ``true`` preview_concurrency_all ^^^^^^^^^^^^^^^^^^^^^^^ :: 'preview_concurrency_all' => 8, Number of all preview requests being processed concurrently, including previews that need to be newly generated, and those that have been generated. This should be greater than ``preview_concurrency_new``. If unspecified, defaults to twice the value of ``preview_concurrency_new``. preview_concurrency_new ^^^^^^^^^^^^^^^^^^^^^^^ :: 'preview_concurrency_new' => 4, Number of new previews that are being concurrently generated. Depending on the max preview size set by ``preview_max_x`` and ``preview_max_y``, the generation process can consume considerable CPU and memory resources. It's recommended to limit this to be no greater than the number of CPU cores. If unspecified, defaults to the number of CPU cores, or 4 if that cannot be determined. preview_max_x ^^^^^^^^^^^^^ :: 'preview_max_x' => 4096, The maximum width, in pixels, of a preview. A value of ``null`` means there is no limit. Defaults to ``4096`` preview_max_y ^^^^^^^^^^^^^ :: 'preview_max_y' => 4096, The maximum height, in pixels, of a preview. A value of ``null`` means there is no limit. Defaults to ``4096`` preview_max_filesize_image ^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'preview_max_filesize_image' => 50, Max file size for generating image previews with imagegd (default behavior). If the image is bigger, it'll try other preview generators, but will most likely either show the default mimetype icon or not display the image at all. Set to ``-1`` for no limit and try to generate image previews on all file sizes. Defaults to ``50`` megabytes preview_max_memory ^^^^^^^^^^^^^^^^^^ :: 'preview_max_memory' => 256, Max memory for generating image previews with imagegd (default behavior) Reads the image dimensions from the header and assumes 32 bits per pixel. If creating the image would allocate more memory, preview generation will be disabled and the default mimetype icon is shown. Set to ``-1`` for no limit. Defaults to ``256`` megabytes preview_libreoffice_path ^^^^^^^^^^^^^^^^^^^^^^^^ :: 'preview_libreoffice_path' => '/usr/bin/libreoffice', Custom path for LibreOffice/OpenOffice binary Defaults to ``''`` (empty string) preview_ffmpeg_path ^^^^^^^^^^^^^^^^^^^ :: 'preview_ffmpeg_path' => '/usr/bin/ffmpeg', Custom path for ffmpeg binary Defaults to ``null`` and falls back to searching ``ffmpeg`` in the configured ``PATH`` environment preview_ffprobe_path ^^^^^^^^^^^^^^^^^^^^ :: 'preview_ffprobe_path' => '/usr/bin/ffprobe', Custom path for ffprobe binary Defaults to ``null`` and falls back to using the same path as ffmpeg. ffprobe is typically packaged with ffmpeg and is required for enhanced preview generation for HDR videos. preview_imaginary_url ^^^^^^^^^^^^^^^^^^^^^ :: 'preview_imaginary_url' => 'http://previews_hpb:8088/', Set the URL of the Imaginary service to send image previews to. Also requires the ``OC\Preview\Imaginary`` provider to be enabled in the ``enabledPreviewProviders`` array, to create previews for these mimetypes: bmp, x-bitmap, png, jpeg, gif, heic, heif, svg+xml, tiff, webp, and illustrator. If you want Imaginary to also create preview images from PDF documents, you have to add the ``OC\Preview\ImaginaryPDF`` provider as well. See https://github.com/h2non/imaginary preview_imaginary_key ^^^^^^^^^^^^^^^^^^^^^ :: 'preview_imaginary_key' => 'secret', If you want to set an API key for Imaginary. enabledPreviewProviders ^^^^^^^^^^^^^^^^^^^^^^^ :: 'enabledPreviewProviders' => [ 'OC\Preview\PNG', 'OC\Preview\JPEG', 'OC\Preview\GIF', 'OC\Preview\BMP', 'OC\Preview\XBitmap', 'OC\Preview\Krita', 'OC\Preview\WebP', 'OC\Preview\MarkDown', 'OC\Preview\TXT', 'OC\Preview\OpenDocument', ], Only register providers that have been explicitly enabled The following providers are disabled by default due to performance or privacy concerns: - ``OC\Preview\EMF`` - ``OC\Preview\Font`` - ``OC\Preview\HEIC`` - ``OC\Preview\Illustrator`` - ``OC\Preview\Movie`` - ``OC\Preview\MP3`` - ``OC\Preview\MSOffice2003`` - ``OC\Preview\MSOffice2007`` - ``OC\Preview\MSOfficeDoc`` - ``OC\Preview\PDF`` - ``OC\Preview\Photoshop`` - ``OC\Preview\Postscript`` - ``OC\Preview\SGI`` - ``OC\Preview\StarOffice`` - ``OC\Preview\SVG`` - ``OC\Preview\TGA`` - ``OC\Preview\TIFF`` The following providers are disabled by default, because they provide an alternative to the built-in providers: - ``OC\Preview\Imaginary`` - ``OC\Preview\ImaginaryPDF`` Defaults to the following providers: - ``OC\Preview\PNG`` - ``OC\Preview\JPEG`` - ``OC\Preview\GIF`` - ``OC\Preview\BMP`` - ``OC\Preview\XBitmap`` - ``OC\Preview\Krita`` - ``OC\Preview\WebP`` - ``OC\Preview\MarkDown`` - ``OC\Preview\TXT`` - ``OC\Preview\OpenDocument`` metadata_max_filesize ^^^^^^^^^^^^^^^^^^^^^ :: 'metadata_max_filesize' => 256, Maximum file size for metadata generation. If a file exceeds this size, metadata generation will be skipped. .. note:: memory equivalent to this size will be used for metadata generation. Default: 256 megabytes. max_file_conversion_filesize ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'max_file_conversion_filesize' => 100, Maximum file size for file conversion. If a file exceeds this size, the file will not be converted. Default: 100 MiB LDAP ---- Global settings used by LDAP User and Group Backend ldapUserCleanupInterval ^^^^^^^^^^^^^^^^^^^^^^^ :: 'ldapUserCleanupInterval' => 51, Defines the interval in minutes for the background job that checks user existence and marks them as ready to be cleaned up. The number is always minutes. Setting it to 0 disables the feature. See command line (occ) methods ``ldap:show-remnants`` and ``user:delete`` Defaults to ``51`` minutes sort_groups_by_name ^^^^^^^^^^^^^^^^^^^ :: 'sort_groups_by_name' => false, Sort groups in the user settings by name instead of the user count By enabling this, the user count beside the group name is disabled as well. .. deprecated:: 29.0.0 Use the frontend instead or set the app config value ``group.sortBy`` for ``core`` to ``2`` Comments -------- Global settings for the Comments infrastructure comments.managerFactory ^^^^^^^^^^^^^^^^^^^^^^^ :: 'comments.managerFactory' => '\OC\Comments\ManagerFactory', Replaces the default Comments Manager Factory. This can be utilized if an own or 3rd-party CommentsManager should be used that – for instance – uses the filesystem instead of the database to keep the comments. Defaults to ``\OC\Comments\ManagerFactory`` systemtags.managerFactory ^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'systemtags.managerFactory' => '\OC\SystemTag\ManagerFactory', Replaces the default System Tags Manager Factory. This can be utilized if an own or 3rd-party SystemTagsManager should be used that – for instance – uses the filesystem instead of the database to keep the tags. Defaults to ``\OC\SystemTag\ManagerFactory`` Maintenance ----------- These options are for halting user activity when you are performing server maintenance. maintenance ^^^^^^^^^^^ :: 'maintenance' => false, Enable maintenance mode to disable Nextcloud If you want to prevent users from logging in to Nextcloud before you start doing some maintenance work, you need to set the value of the maintenance parameter to true. Please keep in mind that users who are already logged in are kicked out of Nextcloud instantly. Defaults to ``false`` maintenance_window_start ^^^^^^^^^^^^^^^^^^^^^^^^ :: 'maintenance_window_start' => 1, UTC Hour for maintenance windows Some background jobs only run once a day. When an hour is defined for this config, the background jobs which advertise themselves as not time sensitive will be delayed during the "working" hours and only run in the 4 hours after the given time. This is, e.g., used for activity expiration, suspicious login training, and update checks. A value of 1, e.g., will only run these background jobs between 01:00am UTC and 05:00am UTC. Defaults to ``100`` which disables the feature ldap_log_file ^^^^^^^^^^^^^ :: 'ldap_log_file' => '', Log all LDAP requests into a file Warning: This heavily decreases the performance of the server and is only meant to debug/profile the LDAP interaction manually. Also, it might log sensitive data into a plain text file. SSL --- openssl ^^^^^^^ :: 'openssl' => [ 'config' => '/absolute/location/of/openssl.cnf', ], Extra SSL options to be used for configuration. Defaults to an empty array. Memory caching backend configuration ------------------------------------ Available cache backends: * ``\OC\Memcache\APCu`` APC user backend * ``\OC\Memcache\ArrayCache`` In-memory array-based backend (not recommended) * ``\OC\Memcache\Memcached`` Memcached backend * ``\OC\Memcache\Redis`` Redis backend Advice on choosing between the various backends: * APCu should be easiest to install. Almost all distributions have packages. Use this for single user environment for all caches. * Use Redis or Memcached for distributed environments. For the local cache (you can configure two) take APCu. memcache.local ^^^^^^^^^^^^^^ :: 'memcache.local' => '\\OC\\Memcache\\APCu', Memory caching backend for locally stored data * Used for host-specific data, e.g., file paths Defaults to ``none`` memcache.distributed ^^^^^^^^^^^^^^^^^^^^ :: 'memcache.distributed' => '\\OC\\Memcache\\Memcached', Memory caching backend for distributed data * Used for installation-specific data, e.g., database caching * If unset, defaults to the value of memcache.local Defaults to ``none`` redis ^^^^^ :: 'redis' => [ 'host' => 'localhost', // can also be a Unix domain socket: '/tmp/redis.sock' 'port' => 6379, 'timeout' => 0.0, 'read_timeout' => 0.0, 'user' => '', // Optional: if not defined, no password will be used. 'password' => '', // Optional: if not defined, no password will be used. 'dbindex' => 0, // Optional: if undefined, SELECT will not run and will use Redis Server's default DB Index. // If Redis in-transit encryption is enabled, provide certificates // SSL context https://www.php.net/manual/en/context.ssl.php 'ssl_context' => [ 'local_cert' => '/certs/redis.crt', 'local_pk' => '/certs/redis.key', 'cafile' => '/certs/ca.crt' ] ], Connection details for Redis to use for memory caching in a single server configuration. For enhanced security, it is recommended to configure Redis to require a password. See http://redis.io/topics/security for more information. We also support Redis SSL/TLS encryption as of version 6. See https://redis.io/topics/encryption for more information. redis.cluster ^^^^^^^^^^^^^ :: 'redis.cluster' => [ 'seeds' => [ // provide some or all of the cluster servers to bootstrap discovery, port required 'localhost:7000', 'localhost:7001', ], 'timeout' => 0.0, 'read_timeout' => 0.0, 'failover_mode' => \RedisCluster::FAILOVER_ERROR, 'user' => '', // Optional: if not defined, no password will be used. 'password' => '', // Optional: if not defined, no password will be used. // If Redis in-transit encryption is enabled, provide certificates // SSL context https://www.php.net/manual/en/context.ssl.php 'ssl_context' => [ 'local_cert' => '/certs/redis.crt', 'local_pk' => '/certs/redis.key', 'cafile' => '/certs/ca.crt' ] ], Connection details for a Redis Cluster. Redis Cluster support requires the PHP module phpredis in version 3.0.0 or higher. Available failover modes: - ``\RedisCluster::FAILOVER_NONE`` - only send commands to master nodes (default) - ``\RedisCluster::FAILOVER_ERROR`` - failover to slaves for read commands if master is unavailable (recommended) - ``\RedisCluster::FAILOVER_DISTRIBUTE`` - randomly distribute read commands across master and slaves .. warning:: ``\RedisCluster::FAILOVER_DISTRIBUTE`` is a not recommended setting, and we strongly suggest to not use it if you use Redis for file locking. Due to the way Redis is synchronized, it could happen that the read for an existing lock is scheduled to a slave that is not fully synchronized with the connected master which then causes a FileLocked exception. See https://redis.io/topics/cluster-spec for details about the Redis cluster Authentication works with phpredis version 4.2.1+. See https://github.com/phpredis/phpredis/commit/c5994f2a42b8a348af92d3acb4edff1328ad8ce1 memcached_servers ^^^^^^^^^^^^^^^^^ :: 'memcached_servers' => [ // hostname, port and optional weight // or path and port 0 for Unix socket. Also see: // https://www.php.net/manual/en/memcached.addservers.php // https://www.php.net/manual/en/memcached.addserver.php ['localhost', 11211], //array('other.host.local', 11211), ], Server details for one or more Memcached servers to use for memory caching. memcached_options ^^^^^^^^^^^^^^^^^ :: 'memcached_options' => [ // Set timeouts to 50ms \Memcached::OPT_CONNECT_TIMEOUT => 50, \Memcached::OPT_RETRY_TIMEOUT => 50, \Memcached::OPT_SEND_TIMEOUT => 50, \Memcached::OPT_RECV_TIMEOUT => 50, \Memcached::OPT_POLL_TIMEOUT => 50, // Enable compression \Memcached::OPT_COMPRESSION => true, // Turn on consistent hashing \Memcached::OPT_LIBKETAMA_COMPATIBLE => true, // Enable Binary Protocol \Memcached::OPT_BINARY_PROTOCOL => true, // Binary serializer will be enabled if the igbinary PECL module is available //\Memcached::OPT_SERIALIZER => \Memcached::SERIALIZER_IGBINARY, ], Connection options for Memcached cache_path ^^^^^^^^^^ :: 'cache_path' => '', Location of the cache folder, defaults to ``data/$user/cache`` where ``$user`` is the current user. When specified, the format will change to ``$cache_path/$user`` where ``$cache_path`` is the configured cache directory and ``$user`` is the user. Defaults to ``''`` (empty string) cache_chunk_gc_ttl ^^^^^^^^^^^^^^^^^^ :: 'cache_chunk_gc_ttl' => 60 * 60 * 24, TTL of chunks located in the cache folder before they're removed by garbage collection (in seconds). Increase this value if users have issues uploading very large files via the Nextcloud Client as upload isn't completed within one day. Defaults to ``60*60*24`` (1 day) cache_app_config ^^^^^^^^^^^^^^^^ :: 'cache_app_config' => true, Enable caching of the app config values. If enabled the app config will be cached locally for a short TTL, reducing database load significantly on larger setups. Defaults to ``true`` Using Object Store with Nextcloud --------------------------------- objectstore ^^^^^^^^^^^ :: 'objectstore' => [ 'class' => 'OC\\Files\\ObjectStore\\Swift', 'arguments' => [ // trystack will use your Facebook ID as the username 'username' => 'facebook100000123456789', // in the trystack dashboard, go to user -> settings -> API Password to // generate a password 'password' => 'Secr3tPaSSWoRdt7', // must already exist in the objectstore, name can be different 'container' => 'nextcloud', // prefix to prepend to the fileid, default is 'oid:urn:' 'objectPrefix' => 'oid:urn:', // create the container if it does not exist. default is false 'autocreate' => true, // required, dev-/trystack defaults to 'RegionOne' 'region' => 'RegionOne', // The Identity / Keystone endpoint 'url' => 'http://8.21.28.222:5000/v2.0', // uploadPartSize: size of the uploaded chunks, defaults to 524288000 'uploadPartSize' => 524288000, // required on dev-/trystack 'tenantName' => 'facebook100000123456789', // dev-/trystack uses swift by default, the lib defaults to 'cloudFiles' // if omitted 'serviceName' => 'swift', // The Interface / URL Type, optional 'urlType' => 'internal', // Maximum amount of data that can be uploaded 'totalSizeLimit' => 1024 * 1024 * 1024, ], ], This example shows how to configure Nextcloud to store all files in a Swift object storage. It is important to note that Nextcloud in object store mode will expect exclusive access to the object store container because it only stores the binary data for each file. The metadata is currently kept in the local database for performance reasons. .. warning:: The current implementation is incompatible with any app that uses direct file I/O and circumvents our virtual filesystem. That includes Encryption and Gallery. Gallery will store thumbnails directly in the filesystem, and encryption will cause severe overhead because key files need to be fetched in addition to any requested file. objectstore ^^^^^^^^^^^ :: 'objectstore' => [ 'class' => 'OC\\Files\\ObjectStore\\Swift', 'arguments' => [ 'autocreate' => true, 'user' => [ 'name' => 'swift', 'password' => 'swift', 'domain' => [ 'name' => 'default', ], ], 'scope' => [ 'project' => [ 'name' => 'service', 'domain' => [ 'name' => 'default', ], ], ], 'tenantName' => 'service', 'serviceName' => 'swift', 'region' => 'regionOne', 'url' => 'http://yourswifthost:5000/v3', 'bucket' => 'nextcloud', ], ], To use Swift V3 objectstore ^^^^^^^^^^^ :: 'objectstore' => [ 'class' => 'OC\\Files\\ObjectStore\\S3', 'arguments' => [ 'bucket' => 'nextcloud', 'key' => 'your-access-key', 'secret' => 'your-secret-key', 'hostname' => 's3.example.com', 'port' => 443, 'use_ssl' => true, 'region' => 'us-east-1', // optional: Maximum number of retry attempts for failed S3 requests // Default: 5 'retriesMaxAttempts' => 5, // Data Integrity Protections for Amazon S3 (https://docs.aws.amazon.com/sdkref/latest/guide/feature-dataintegrity.html) // Valid values are "when_required" (default) and "when_supported". // To ensure compatibility with 3rd party S3 implementations, Nextcloud disables it by default. However, if you are // using Amazon S3 (or any other implementation that supports it) we recommend enabling it by using "when_supported". 'request_checksum_calculation' => 'when_required', 'response_checksum_validation' => 'when_required', ], ], To use S3 object storage objectstore.multibucket.preview-distribution ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'objectstore.multibucket.preview-distribution' => false, If this is set to true and a multibucket object store is configured, then newly created previews are put into 256 dedicated buckets. Those buckets are named like the multibucket version but with the postfix ``-preview-NUMBER`` where NUMBER is between 0 and 255. Keep in mind that only previews of files are put in there that don't have some already. Otherwise, the old bucket will be used. To migrate existing previews to this new multibucket distribution of previews, use the occ command ``preview:repair``. For now, this will only migrate previews that were generated before Nextcloud 19 in the flat ``appdata_INSTANCEID/previews/FILEID`` folder structure. Sharing ------- Global settings for Sharing sharing.managerFactory ^^^^^^^^^^^^^^^^^^^^^^ :: 'sharing.managerFactory' => '\OC\Share20\ProviderFactory', Replaces the default Share Provider Factory. This can be utilized if own or 3rd-party Share Providers are used that – for instance – use the filesystem instead of the database to keep the share information. Defaults to ``\OC\Share20\ProviderFactory`` sharing.enable_mail_link_password_expiration ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'sharing.enable_mail_link_password_expiration' => false, Enables expiration for link share passwords sent by email (sharebymail). The passwords will expire after the configured interval; the users can still request a new one on the public link page. sharing.mail_link_password_expiration_interval ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'sharing.mail_link_password_expiration_interval' => 3600, Expiration interval for passwords, in seconds. sharing.maxAutocompleteResults ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'sharing.maxAutocompleteResults' => 25, Define max number of results returned by the search for auto-completion of users, groups, etc. The value must not be lower than 0 (for unlimited). If more, different sources are requested (e.g., different user backends; or both users and groups), the value is applied per source and might not be truncated after collecting the results. I.e., more results can appear than configured here. Default is 25. sharing.minSearchStringLength ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'sharing.minSearchStringLength' => 0, Define the minimum length of the search string before we start auto-completion Default is no limit (value set to 0) sharing.enable_share_accept ^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'sharing.enable_share_accept' => false, Set to true to enable that internal shares need to be accepted by the users by default. Users can change this for their account in their personal sharing settings sharing.force_share_accept ^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'sharing.force_share_accept' => false, Set to ``true`` to enforce that internal shares need to be accepted sharing.allow_custom_share_folder ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'sharing.allow_custom_share_folder' => true, Set to ``false`` to prevent users from setting a custom share_folder share_folder ^^^^^^^^^^^^ :: 'share_folder' => '/', Define a default folder for shared files and folders other than root. Changes to this value will only have effect on new shares. Defaults to ``/`` sharing.enable_share_mail ^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'sharing.enable_share_mail' => true, Set to ``false`` to stop sending a mail when users receive a share sharing.allow_disabled_password_enforcement_groups ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'sharing.allow_disabled_password_enforcement_groups' => false, Set to true to enable the feature to add exceptions for share password enforcement transferIncomingShares ^^^^^^^^^^^^^^^^^^^^^^ :: 'transferIncomingShares' => false, Set to true to always transfer incoming shares by default when running ``occ files:transfer-ownership``. Defaults to ``false``, so incoming shares are not transferred if not specifically requested by a command line argument. Federated Cloud Sharing ----------------------- sharing.federation.allowSelfSignedCertificates ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'sharing.federation.allowSelfSignedCertificates' => false, Allow self-signed certificates for federated shares Hashing ------- hashing_default_password ^^^^^^^^^^^^^^^^^^^^^^^^ :: 'hashing_default_password' => false, By default, Nextcloud will use the Argon2 password hashing if available. However, if for whatever reason you want to stick with the PASSWORD_DEFAULT of your PHP version, then set the setting to true. Nextcloud uses the Argon2 algorithm (with PHP >= 7.2) to create hashes by its own and exposes its configuration options as following. More information can be found at: https://www.php.net/manual/en/function.password-hash.php hashingThreads ^^^^^^^^^^^^^^ :: 'hashingThreads' => PASSWORD_ARGON2_DEFAULT_THREADS, The number of CPU threads to be used by the algorithm for computing a hash. The value must be an integer, and the minimum value is ``1``. Rationally, it does not help to provide a number higher than the available threads on the machine. Values that undershoot the minimum will be ignored in favor of the minimum. hashingMemoryCost ^^^^^^^^^^^^^^^^^ :: 'hashingMemoryCost' => PASSWORD_ARGON2_DEFAULT_MEMORY_COST, The memory in KiB to be used by the algorithm for computing a hash. The value must be an integer, and the minimum value is 8 times the number of CPU threads. Values that undershoot the minimum will be ignored in favor of the minimum. hashingTimeCost ^^^^^^^^^^^^^^^ :: 'hashingTimeCost' => PASSWORD_ARGON2_DEFAULT_TIME_COST, The number of iterations that are used by the algorithm for computing a hash. The value must be an integer, and the minimum value is ``1``. Values that undershoot the minimum will be ignored in favor of the minimum. hashingCost ^^^^^^^^^^^ :: 'hashingCost' => 10, The hashing cost used by hashes generated by Nextcloud Using a higher value requires more time and CPU power to calculate the hashes All other configuration options ------------------------------- dbdriveroptions ^^^^^^^^^^^^^^^ :: 'dbdriveroptions' => [ PDO::MYSQL_ATTR_SSL_CA => '/file/path/to/ca_cert.pem', PDO::MYSQL_ATTR_SSL_KEY => '/file/path/to/mysql-client-key.pem', PDO::MYSQL_ATTR_SSL_CERT => '/file/path/to/mysql-client-cert.pem', PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT => false, PDO::MYSQL_ATTR_INIT_COMMAND => 'SET wait_timeout = 28800' ], Additional driver options for the database connection, e.g., to enable SSL encryption in MySQL or specify a custom wait timeout on a cheap hoster. When setting up TLS/SSL for encrypting the connections, you need to ensure that the passed keys and certificates are readable by the PHP process. In addition, ``PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT`` might need to be set to false, if the database server's certificate CN does not match with the hostname used to connect. The standard behavior here is different from the MySQL/MariaDB CLI client, which does not verify the server cert except ``--ssl-verify-server-cert`` is passed manually. sqlite.journal_mode ^^^^^^^^^^^^^^^^^^^ :: 'sqlite.journal_mode' => 'DELETE', SQLite3 journal mode can be specified using this configuration parameter - can be ``'WAL'`` or ``'DELETE'``. See https://www.sqlite.org/wal.html for more details. mysql.utf8mb4 ^^^^^^^^^^^^^ :: 'mysql.utf8mb4' => false, During setup, if requirements are met (see below), this setting is set to true to enable MySQL to handle 4-byte characters instead of 3-byte characters. To convert an existing 3-byte setup to a 4-byte setup, configure the MySQL parameters as described below and run the migration command: ``./occ db:convert-mysql-charset`` This config setting will be automatically updated after a successful migration. Refer to the documentation for more details. MySQL requires specific settings for longer indexes (> 767 bytes), which are necessary for 4-byte character support:: [mysqld] innodb_large_prefix=ON innodb_file_format=Barracuda innodb_file_per_table=ON Tables will be created with: * character set: ``utf8mb4`` * collation: ``utf8mb4_bin`` * row_format: ``dynamic`` See: * https://dev.mysql.com/doc/refman/5.7/en/charset-unicode-utf8mb4.html * https://dev.mysql.com/doc/refman/5.7/en/innodb-parameters.html#sysvar_innodb_large_prefix * https://mariadb.com/kb/en/mariadb/xtradbinnodb-server-system-variables/#innodb_large_prefix * http://www.tocker.ca/2013/10/31/benchmarking-innodb-page-compression-performance.html * http://mechanics.flite.com/blog/2014/07/29/using-innodb-large-prefix-to-avoid-error-1071/ mysql.collation ^^^^^^^^^^^^^^^ :: 'mysql.collation' => null, For search queries in the database, a default collation is chosen based on the character set. In some cases, a different collation is desired, such as for accent-sensitive searches. MariaDB and MySQL share some collations, but also have incompatible ones, depending on the database server version. This option allows overriding the automatic collation choice. Example:: 'mysql.collation' => 'utf8mb4_0900_as_ci', This setting does not affect table creation or setup, where utf8[mb4]_bin is always used. It applies only to SQL queries using LIKE comparison operators. pgsql_ssl ^^^^^^^^^ :: 'pgsql_ssl' => [ 'mode' => '', 'cert' => '', 'rootcert' => '', 'key' => '', 'crl' => '', ], PostgreSQL SSL connection supportedDatabases ^^^^^^^^^^^^^^^^^^ :: 'supportedDatabases' => [ 'sqlite', 'mysql', 'pgsql', 'oci', ], Database types supported for installation. Available: - sqlite (SQLite3) - mysql (MySQL) - pgsql (PostgreSQL) - oci (Oracle) Defaults to: - sqlite (SQLite3) - mysql (MySQL) - pgsql (PostgreSQL) tempdirectory ^^^^^^^^^^^^^ :: 'tempdirectory' => '/tmp/nextcloudtemp', Override the location where Nextcloud stores temporary files. Useful in setups where the system temporary directory is on a limited-space ramdisk, restricted, or when using external storage that does not support streaming. The web server user/PHP must have write access to this directory. Ensure that PHP configuration recognizes this as a valid temporary directory by setting the TMP, TMPDIR, and TEMP environment variables accordingly. Additional permissions may be required for AppArmor or SELinux. updatedirectory ^^^^^^^^^^^^^^^ :: 'updatedirectory' => '', Override the location where Nextcloud stores update files during updates. Useful when the default ``datadirectory`` is on a network disk like NFS or is otherwise restricted. Defaults to the value of ``datadirectory`` if unset. If set, the directory must be located outside the Nextcloud installation directory and writable by the web server user. forbidden_filenames ^^^^^^^^^^^^^^^^^^^ :: 'forbidden_filenames' => ['.htaccess'], Block specific files or filenames, disallowing uploads or access (read and write). ``.htaccess`` is blocked by default. .. warning:: Use this only if you understand the implications. .. note:: This list is case-insensitive. Defaults to ``['.htaccess']`` forbidden_filename_basenames ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'forbidden_filename_basenames' => [], Disallow uploads of files with specific basenames. Matching existing files cannot be updated, and no new files can be created in matching folders. The basename is the filename without the extension, e.g., for "archive.tar.gz", the basename is "archive". .. note:: This list is case-insensitive. Defaults to ``[]`` (empty array) forbidden_filename_characters ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'forbidden_filename_characters' => [], Block specific characters in filenames. Useful for filesystems or operating systems (e.g., Windows) that do not support certain characters. Matching existing files cannot be updated, and no new files can be created in matching folders. The ``/`` and ``\`` characters, as well as ASCII characters [0-31], are always forbidden. Example for Windows: ``['?', '<', '>', ':', '*', '|', '"']`` See: https://en.wikipedia.org/wiki/Comparison_of_file_systems#Limits Defaults to ``[]`` (empty array) forbidden_filename_extensions ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'forbidden_filename_extensions' => ['.part', '.filepart'], Deny specific file extensions. Matching existing files cannot be updated, and no new files can be created in matching folders. The ``'.part'`` extension is always forbidden, as it is used internally by Nextcloud. Defaults to ``['.filepart', '.part']`` theme ^^^^^ :: 'theme' => '', Specify the name of a theme to apply to Nextcloud. Themes are located in ``nextcloud/themes/`` by default. Defaults to the theming app, included since Nextcloud 9. enforce_theme ^^^^^^^^^^^^^ :: 'enforce_theme' => '', Enforce a specific user theme, disabling user theming settings. Must be a valid ITheme ID, e.g., ``dark``, ``dark-highcontrast``, ``default``, ``light``, ``light-highcontrast``, ``opendyslexic``. theming.standalone_window.enabled ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'theming.standalone_window.enabled' => true, Enable or disable Progressive Web App (PWA) functionality, which allows browsers to open web applications in dedicated windows. Defaults to ``true`` cipher ^^^^^^ :: 'cipher' => 'AES-256-CTR', Specify the default cipher for encrypting files. Supported ciphers: - AES-256-CTR - AES-128-CTR - AES-256-CFB - AES-128-CFB Defaults to ``AES-256-CTR`` encryption.use_legacy_base64_encoding ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'encryption.use_legacy_base64_encoding' => false, Use the legacy base64 format for encrypted files instead of the more space-efficient binary format. This affects only newly written files; existing encrypted files remain readable regardless of the format. Defaults to ``false`` minimum.supported.desktop.version ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'minimum.supported.desktop.version' => '3.0.82', Specify the minimum Nextcloud desktop client version allowed to sync with this server. Connections from earlier clients will be denied. Defaults to the minimum officially supported version at the time of this server release. Changing this may cause older, unsupported clients to malfunction, potentially leading to data loss or unexpected behavior. Defaults to ``3.0.82`` maximum.supported.desktop.version ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'maximum.supported.desktop.version' => '99.99.99', Specify the maximum Nextcloud desktop client version allowed to sync with this server. Connections from later clients will be denied. Defaults to ``99.99.99`` localstorage.allowsymlinks ^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'localstorage.allowsymlinks' => false, Allow local storage to contain symlinks. .. warning:: Not recommended, as this allows Nextcloud to access files outside the data directory, posing a potential security risk. Defaults to ``false`` localstorage.umask ^^^^^^^^^^^^^^^^^^ :: 'localstorage.umask' => 0022, Nextcloud overrides umask to ensure suitable access permissions regardless of web server or PHP-FPM configuration. Modifying this value has security implications and may cause issues with the installation. Most installations should not modify this value. Defaults to ``0022`` localstorage.unlink_on_truncate ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'localstorage.unlink_on_truncate' => false, Allow storage systems that do not support modifying existing files to overcome this limitation by removing files before overwriting. Defaults to ``false`` quota_include_external_storage ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'quota_include_external_storage' => false, EXPERIMENTAL: Include external storage in quota calculations. Defaults to ``false`` external_storage.auth_availability_delay ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'external_storage.auth_availability_delay' => 1800, When an external storage is unavailable (e.g., due to failed authentication), it is flagged as such for a specified duration. For authentication failures, this delay can be customized to reduce the likelihood of account lockouts in systems like Active Directory. Defaults to ``1800`` seconds (30 minutes) files_external_allow_create_new_local ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'files_external_allow_create_new_local' => true, Allow creation of external storages of type "Local" via the web interface and APIs. When disabled, local storages can still be created using the occ command:: occ files_external:create /mountpoint local null::null -c datadir=/path/to/data Defaults to ``true`` filesystem_check_changes ^^^^^^^^^^^^^^^^^^^^^^^^ :: 'filesystem_check_changes' => 0, Specify how often the local filesystem (Nextcloud data/ directory and NFS mounts in data/) is checked for changes made outside Nextcloud. This does not apply to external storage. - ``0`` -> Never check the filesystem for outside changes, improving performance when no external changes are expected. - ``1`` -> Check each file or folder at most once per request, recommended for general use if outside changes are possible. Defaults to ``0`` part_file_in_storage ^^^^^^^^^^^^^^^^^^^^ :: 'part_file_in_storage' => true, Store part files created during upload in the same storage as the upload target. Setting this to false stores part files in the root of the user's folder, which may be necessary for external storage with limited rename capabilities. Defaults to ``true`` mount_file ^^^^^^^^^^ :: 'mount_file' => '/var/www/nextcloud/data/mount.json', Specify the location of the ``mount.json`` file. Defaults to ``data/mount.json`` in the Nextcloud directory. filesystem_cache_readonly ^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'filesystem_cache_readonly' => false, Prevent Nextcloud from updating the cache due to filesystem changes for all storage. Defaults to ``false`` trusted_proxies ^^^^^^^^^^^^^^^ :: 'trusted_proxies' => ['203.0.113.45', '198.51.100.128', '192.168.2.0/24'], List of trusted proxy servers.

Ensure ``forwarded_for_headers`` is configured if ``trusted_proxies`` is set. Defaults to ``[]`` (empty array) forwarded_for_headers ^^^^^^^^^^^^^^^^^^^^^ :: 'forwarded_for_headers' => ['HTTP_X_FORWARDED', 'HTTP_FORWARDED_FOR'], Headers trusted as containing the client IP address when used with ``trusted_proxies``. For example, use ``HTTP_X_FORWARDED_FOR`` for the ``X-Forwarded-For`` header. Incorrect configuration allows clients to spoof their IP address, bypassing access controls and rendering logs unreliable. Defaults to ``['HTTP_X_FORWARDED_FOR']`` allowed_admin_ranges ^^^^^^^^^^^^^^^^^^^^ :: 'allowed_admin_ranges' => ['192.0.2.42/32', '233.252.0.0/24', '2001:db8::13:37/64'], List of trusted IP ranges for admin actions. If non-empty, all admin actions must originate from IPs within these ranges. Supported formats: - IPv4 addresses or ranges, e.g., ``192.0.2.42/32``, ``233.252.0.0/24`` - IPv6 addresses or ranges, e.g., ``2001:db8::13:37/64`` Defaults to ``[]`` (empty array) max_filesize_animated_gifs_public_sharing ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ :: 'max_filesize_animated_gifs_public_sharing' => 10, Maximum file size (in megabytes) for animating GIFs on public sharing pages.

Defaults to ``10`` megabytes filelocking.ttl ^^^^^^^^^^^^^^^ :: 'filelocking.ttl' => 60 * 60, Set the lock's time-to-live (TTL) in seconds. Locks older than this are automatically cleaned up. Defaults to ``3600`` seconds (1 hour) or the PHP ``max_execution_time``, whichever is higher. memcache.locking ^^^^^^^^^^^^^^^^ :: 'memcache.locking' => '\\OC\\Memcache\\Redis', Memory caching backend for file locking. Redis is highly recommended to avoid data loss, as many memcache backends may evict values unexpectedly. Defaults to ``none`` filelocking.debug ^^^^^^^^^^^^^^^^^ :: 'filelocking.debug' => false, Enable debug logging for file locking.

Defaults to ``false`` data-fingerprint ^^^^^^^^^^^^^^^^ :: 'data-fingerprint' => '', Set the data fingerprint for the current data served. Used by clients to detect if a backup has been restored. Update this by running:: occ maintenance:data-fingerprint Changing or deleting this value may cause connected clients to stall until conflicts are resolved. Defaults to ``''`` (empty string) copied_sample_config ^^^^^^^^^^^^^^^^^^^^ :: 'copied_sample_config' => true, This entry serves as a warning if the sample configuration was copied. DO NOT ADD THIS TO YOUR CONFIGURATION! Ensure all settings are modified only after consulting the documentation. lookup_server ^^^^^^^^^^^^^ :: 'lookup_server' => 'https://lookup.nextcloud.com', Use a custom lookup server to publish user data. Defaults to ``https://lookup.nextcloud.com`` gs.enabled ^^^^^^^^^^ :: 'gs.enabled' => false, Enable Nextcloud's Global Scale architecture.
