System Requirements¶

Memory¶

See Installation on Linux for minimum software versions for installing Nextcloud.

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: MySQL / MariaDB with Binary Logging Enabled)
InnoDB storage engine (MyISAM is not supported)
“READ COMMITED” transaction isolation level (See: Database “READ COMMITED” transaction isolation level)

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 Enabling MySQL 4-byte support for more information.
