mariadbd Options

A reference list of command-line options available for the `mariadbd` server binary, covering configuration, replication, and service installation.

This page lists all of the options for mariadbd (called mysqld before ), 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.

Previously, the client used to be called mysqld, and can still be accessed under this name, via a symlink in Linux, or an alternate binary in Windows.

  • 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.
