This page lists all of the options for mariadbd (called mysqld before MariaDB 10.5), ordered by topic. For a full alphabetical list of all mariadbd options, as well as server and status variables, see Full list of MariaDB options, system and status variables.

In many cases, the entry here is a summary, and links to the full description.

By convention, server variables have usually been specified with an underscore in the configuration files, and a dash on the command line. You can however specify underscores as dashes - they are interchangeable.

See Configuring MariaDB with Option Files for which files and groups mariadbd reads for it's default options.

Option Prefixes

--autoset-*

  • Description: Sets the option value automatically. Only supported for certain options.

--disable-*

  • Description: For all boolean options, disables the setting (equivalent to setting it to 0). Same as --skip.

--enable-*

--loose-*

  • Description: Don't produce an error if the option doesn't exist.

--maximum-*

  • Description: Sets the maximum value for the option.

--skip-*

  • Description: For all boolean options, disables the setting (equivalent to setting it to 0). Same as --disable.

--plugin-load

  • Commandline: --plugin-load=name
  • Description: This option can be used to configure the server to load specific plugins. This option uses the following format:
    • Plugins can be specified in the format name=library, where name is the plugin name and library is the plugin library. This format installs a single plugin from the given plugin library.
    • Plugins can also be specified in the format library, where library is the plugin library. This format installs all plugins from the given plugin library.
    • Multiple plugins can be specified by separating them with semicolons.
  • Special care must be taken when specifying the --plugin-load option multiple times, or when specifying both the --plugin-load option and the --plugin-load-add option together. The --plugin-load option resets the plugin load list, and this can cause unexpected problems if you are not aware. The --plugin-load-add option does not reset the plugin load list, so it is much safer to use. See Plugin Overview: Specifying Multiple Plugin Load Options for more information.
  • See Plugin Overview: Installing a Plugin with Plugin Load Options for more information.

--plugin-load-add

  • Commandline: --plugin-load-add=name
  • Description: This option can be used to configure the server to load specific plugins. This option uses the following format:

    • Plugins can also be specified in the format library, where library is the plugin library. This format installs all plugins from the given plugin library.
    • Multiple plugins can be specified by separating them with semicolons.
  • Special care must be taken when specifying both the --plugin-load option and the --plugin-load-add option together. The --plugin-load option resets the plugin load list, and this can cause unexpected problems if you are not aware. The --plugin-load-add option does not reset the plugin load list, so it is much safer to use. See Plugin Overview: Specifying Multiple Plugin Load Options for more information.
  • See Plugin Overview: Installing a Plugin with Plugin Load Options for more information.

--show-slave-auth-info

  • Commandline: --show-slave-auth-info
  • Description: Show user and password in SHOW SLAVE HOSTS on this primary.

  • Description: If set, replica is not autostarted.

--skip-ssl



--skip-thread-priority

  • Commandline: --skip-thread-priority

Manual heuristic recovery may be needed if the transaction coordination log is missing or if it doesn't contain all prepared transactions. This option can be set to OFF, COMMIT, or ROLLBACK. The default is OFF. See also the --log-tc server option and the log_tc_size system variable.

--temp-pool

  • Commandline: --temp-pool
  • Description: Using this option will cause most temporary files created to use a small set of names, rather than a unique name for each new file. Defaults to 1 until MariaDB 10.5.6, use --skip-temp-pool to disable. Deprecated and defaults to 0 from MariaDB 10.5.7, as benchmarking shows it causes a heavy mutex contention.
