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 Section 4.2.3.3, “Using Option
Files”.
· --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 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.
