MARIADB-PLUGIN(1) MariaDB Database System MARIADB-PLUGIN(1)
mariadb-plugin - configure MariaDB server plugins (mysql_plugin
is now a symlink to mariadb-plugin)
mysql_plugin [options] plugin {ENABLE|DISABLE}
The mysql_plugin utility enables MariaDB administrators to manage
which plugins a MariaDB server loads. It provides an alternative
to manually specifying the --plugin-load option at server startup
or using the INSTALL PLUGIN and UNINSTALL PLUGIN statements at
runtime.
Depending on whether mysql_plugin is invoked to enable or disable
plugins, it inserts or deletes rows in the mysql.plugin table
that serves as a plugin registry. (To perform this operation,
mysql_plugin invokes the MariaDB server in bootstrap mode. This
means that the server must not already be running.) For normal
server startups, the server loads and enables plugins listed in
mysql.plugin automatically. For additional control over plugin
activation, use --plugin_name options named for specific plugins.
Each invocation of mysql_plugin reads a configuration file to
determine how to configure the plugins contained in a single
plugin library object file. To invoke mysql_plugin, use this
syntax:
mysql_plugin [options] plugin {ENABLE|DISABLE}
plugin is the name of the plugin to configure. ENABLE or DISABLE
(not case sensitive) specify whether to enable or disable
components of the plugin library named in the configuration file.
The order of the plugin and ENABLE or DISABLE arguments does not
matter.
For example, to configure components of a plugin library file
named myplugins.so on Linux or myplugins.dll on Windows, specify
a plugin value of myplugins. Suppose that this plugin library
contains three plugins, plugin1, plugin2, and plugin3, all of
which should be configured under mysql_plugin control. By
convention, configuration files have a suffix of .ini and the
same basename as the plugin library, so the default configuration
file name for this plugin library is myplugins.ini. The
configuration file contents look like this:
myplugins
plugin1
plugin2
plugin3
The first line in the myplugins.ini file is the name of the
library object file, without any extension such as .so or .dll.
The remaining lines are the names of the components to be enabled
or disabled. Each value in the file should be on a separate line.
Lines on which the first character is '#' are taken as comments
and ignored.
To enable the plugins listed in the configuration file, invoke
mysql_plugin this way:
shell> mysql_plugin myplugins ENABLE
To disable the plugins, use DISABLE rather than ENABLE.
An error occurs if mysql_plugin cannot find the configuration
file or plugin library file, or if mysql_plugin cannot start the
MariaDB server.
mysql_plugin supports the following options, which can be
specified on the command line or in the [mysqld] group of any
option file. For options specified in a [mysqld] group,
mysql_plugin recognizes the --basedir, --datadir, and
--plugin-dir options and ignores others.
mysql_plugin Options
• --help, -?
Display a help message and exit.
• --basedir=path, -b path
The server base directory.
• --datadir=path, -d path
The server data directory.
• --my-print-defaults=path, -b path
The path to the my_print_defaults program.
• --mysqld=path, -b path
The path to the mysqld server.
• --no-defaults, -p
Do not read values from the configuration file. This option
enables an administrator to skip reading defaults from the
configuration file.
With mysql_plugin, this option need not be given first on the
command line, unlike most other MariaDB programs that support
--no-defaults.
• --plugin-dir=path, -p path
The server plugin directory.
• --plugin-ini=file_name, -i file_name
The mysql_plugin configuration file. Relative path names are
interpreted relative to the current directory. If this option
is not given, the default is plugin.ini in the plugin
directory, where plugin is the plugin argument on the command
line.
• --print-defaults, -P
Display the default values from the configuration file. This
option causes mysql_plugin to print the defaults for
--basedir, --datadir, and --plugin-dir if they are found in
the configuration file. If no value for a variable is found,
nothing is shown.
With mysql_plugin, this option need not be given first on the
command line, unlike most other MariaDB programs that support
--print-defaults.
• --verbose, -v
Verbose mode. Print more information about what the program
does. This option can be used multiple times to increase the
amount of information.
• --version, -V
Display version information and exit.
