|
|
|
Memory requirements for running an Nextcloud server are greatly variable,
|
|
depending on the numbers of users and files, and volume of server activity.
|
|
Nextcloud needs a minimum of 128MB RAM, and we recommend a minimum of 512MB.
|
|
|
|

|
|
Database Requirements for MySQL / MariaDB
|
|
-----------------------------------------
|
|
|
|
The following is currently required if you're running Nextcloud together with a MySQL / MariaDB database:
|
|
|
|
* Disabled or BINLOG_FORMAT = MIXED configured Binary Logging (See: :ref:`db-binlog-label`)
|
|
* InnoDB storage engine (MyISAM is not supported)
|
|
* "READ COMMITED" transaction isolation level (See: :ref:`db-transaction-label`)
|
|
|
|
Emoji (UTF8 4-byte) support with MySQL / MariaDB
|
|
================================================
|
|
If you want to use UTF8 4-byte characters such as Emojis on your server, the database needs to be created with character set ``utf8mb4`` and collate ``utf8mb4_general_ci``, e.g.::
|
|
|
|
CREATE DATABASE nextcloud CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;
|
|
|
|
Additionally the following InnoDB settings need to be set::
|
|
|
|
[mysqld]
|
|
innodb_large_prefix=on
|
|
innodb_file_format=barracuda
|
|
innodb_file_per_table=true
|
|
|
|
See :doc:`../maintenance/mysql_4byte_support` for more information.
