NAME

       mysql_plugin - configure MySQL server plugins

SYNOPSIS

       mysql_plugin [options] plugin {ENABLE|DISABLE}

DESCRIPTION

           Note
           mysql_plugin is deprecated as of MySQL 5.7.11 and removed in MySQL 8.0. Alternatives
           include loading plugins at server startup using the --plugin-load or --plugin-load-add
           option, or at runtime using the INSTALL PLUGIN statement.

       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.

       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 5.5.1, “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 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 base name 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 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 used by MySQL programs, see Section 4.2.2.2,
       “Using Option Files”.

       •   --help, -?  Display a help message and exit.

       •   --basedir=dir_name, -b dir_name The server base directory.

       •   --datadir=dir_name, -d dir_name The server data directory.

       •   --my-print-defaults=file_name, -b file_name The path to the my_print_defaults program.

       •   --mysqld=file_name, -b file_name 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=dir_name, -p dir_name 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.
