|
||||
You can
|
||||
check the presence of a module by typing ``php -m | grep -i <module_name>``.
|
||||
If you get a result, the module is present.

|
||||
|
||||
*Recommended* packages:

||||
* PHP module intl (increases language translation performance and fixes sorting
|
||||
of non-ASCII characters)
|
||||
* PHP module sodium (for Argon2 for password hashing. bcrypt is used as fallback, but if passwords were hashed with Argon2 already and the module is missing, your users can't log in.)

||||
|
||||
Required for specific apps:
|
||||
|
||||
* PHP module ldap (for LDAP integration)
|
||||

|
||||
memcaches:
|
||||
|
||||
* PHP module apcu (>= 4.0.6)
|
||||
* PHP module memcached
|
||||
* PHP module redis (>= 2.2.6, required for Transactional File Locking)
|
||||

See https://cromwell-intl.com/open-source/pdf-not-authorized.html
|
||||
|
||||

|
||||
|
||||

|
||||
in your php.ini by the ``disable_functions`` option.
|
||||
|
||||
For command line updater (*optional*):
|
||||
|
||||
* PHP module phar (upgrades Nextcloud by running ``sudo -u www-data php /var/www/nextcloud/updater/updater.phar``)
|
||||
|
||||
ini values
|
||||
----------
|
||||
|
||||
The following ini settings should be adapted if needed for Nextcloud:
|
||||
|
||||
* ``apc.enable_cli``: See :doc:`../configuration_server/caching_configuration`
|
||||
* ``disable_functions``: Avoid disabling functions unless you know exactly what you are doing
|
||||
* ``max_execution_time``: See :doc:`../configuration_files/big_file_upload_configuration`
|
||||
* ``memory_limit``: Should at least 512MB. See also :doc:`../configuration_files/big_file_upload_configuration`
