MYSQL_PLUGIN(1)                                 MySQL Database System                                 MYSQL_PLUGIN(1)



NAME
       mysql_plugin - configure MySQL server plugins

SYNOPSIS
       mysql_plugin [options] plugin {ENABLE|DISABLE}

DESCRIPTION
       The mysql_plugin utility enables MySQL administrators to manage which plugins a MySQL 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.  mysql_plugin is available as of MySQL 5.5.16.

       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
       MySQL 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, as described in Section 5.1.8.1,
       “Installing and Uninstalling 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 MySQL 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. For information about option files, see
       ·   --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 MySQL
           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 MySQL
           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.
