MariaDB starting with 5.5

mysql_plugin was introduced in MariaDB 5.5.

mysql_plugin is a tool for enabling or disabling plugins.

It is a commandline alternative to the INSTALL PLUGIN and UNINSTALL PLUGIN statements, and the --plugin-load option to mysqld.

mysql_plugin must be run while the server is offline, and works by adding or removing rows from the mysql.plugin table.

Usage

mysql_plugin [options] <plugin> ENABLE|DISABLE

mysql_plugin expects to find a configuration file that indicates how to configure the plugins. The configuration file is by default the same name as the plugin, with a .ini extension. For example:

mysql_plugin crazyplugins ENABLE

Here, mysql_plugin will look for a file called crazyplugins.ini

crazyplugins
crazyplugin1
crazyplugin2
crazyplugin3

The first line should contain the name of the library object file, with no extension. The other lines list the names of the components. Each value should be on a separate line, and the # character at the start of the line indicates a comment.

Options

The following options can be specified on the command line, while some can be specified in the [mysqld] group of any option file. For options specified in a [mysqld] group, only the --basedir, --datadir, and --plugin-dir options can be used - the rest are ignored.

OptionDescription
-b, --basedir=nameThe base directory for the server.
-d, --datadir=nameThe data directory for the server.

-p, --plugin-dir=nameThe plugin directory for the server.
