NAME

6       mysql_plugin - configure MariaDB server plugins
7

SYNOPSIS

9       mysql_plugin [options] plugin {ENABLE|DISABLE}
10

DESCRIPTION

12       The mysql_plugin utility enables MariaDB administrators to manage which
13       plugins a MariaDB server loads. It provides an alternative to manually
14       specifying the --plugin-load option at server startup or using the
15       INSTALL PLUGIN and UNINSTALL PLUGIN statements at runtime.
16
17       Depending on whether mysql_plugin is invoked to enable or disable
18       plugins, it inserts or deletes rows in the mysql.plugin table that
19       serves as a plugin registry. (To perform this operation, mysql_plugin
20       invokes the MariaDB server in bootstrap mode. This means that the
21       server must not already be running.) For normal server startups, the
22       server loads and enables plugins listed in mysql.plugin automatically.
23       For additional control over plugin activation, use --plugin_name
24       options named for specific plugins.
25
26       Each invocation of mysql_plugin reads a configuration file to determine
27       how to configure the plugins contained in a single plugin library
28       object file. To invoke mysql_plugin, use this syntax:
29
30           mysql_plugin [options] plugin {ENABLE|DISABLE}
31
32       plugin is the name of the plugin to configure.  ENABLE or DISABLE (not
33       case sensitive) specify whether to enable or disable components of the
34       plugin library named in the configuration file. The order of the plugin
35       and ENABLE or DISABLE arguments does not matter.
36
37       For example, to configure components of a plugin library file named
38       myplugins.so on Linux or myplugins.dll on Windows, specify a plugin
39       value of myplugins. Suppose that this plugin library contains three
40       plugins, plugin1, plugin2, and plugin3, all of which should be
41       configured under mysql_plugin control. By convention, configuration
42       files have a suffix of .ini and the same basename as the plugin
43       library, so the default configuration file name for this plugin library
44       is myplugins.ini. The configuration file contents look like this:
45
46           myplugins
47           plugin1
48           plugin2
49           plugin3
50
51       The first line in the myplugins.ini file is the name of the library
52       object file, without any extension such as .so or .dll. The remaining
53       lines are the names of the components to be enabled or disabled. Each
54       value in the file should be on a separate line. Lines on which the
55       first character is '#' are taken as comments and ignored.
56
57       To enable the plugins listed in the configuration file, invoke
58       mysql_plugin this way:
59
60           shell> mysql_plugin myplugins ENABLE
61
62       To disable the plugins, use DISABLE rather than ENABLE.
63
64       An error occurs if mysql_plugin cannot find the configuration file or
65       plugin library file, or if mysql_plugin cannot start the MariaDB
66       server.
67
68       mysql_plugin supports the following options, which can be specified on
69       the command line or in the [mysqld] group of any option file. For
70       options specified in a [mysqld] group, mysql_plugin recognizes the
71       --basedir, --datadir, and --plugin-dir options and ignores others.

73       mysql_plugin Options
74
75       ·   --help, -?
76
77           Display a help message and exit.
78
79       ·   --basedir=path, -b path
80
81           The server base directory.
82
83       ·   --datadir=path, -d path
84
85           The server data directory.
86
87       ·   --my-print-defaults=path, -b path
88
89           The path to the my_print_defaults program.
90
91       ·   --mysqld=path, -b path
92
93           The path to the mysqld server.
94
95       ·   --no-defaults, -p
96
97           Do not read values from the configuration file. This option enables
98           an administrator to skip reading defaults from the configuration
99           file.
100
101           With mysql_plugin, this option need not be given first on the
102           command line, unlike most other MariaDB programs that support
103           --no-defaults.
104
105       ·   --plugin-dir=path, -p path
106
107           The server plugin directory.
108
109       ·   --plugin-ini=file_name, -i file_name
110
111           The mysql_plugin configuration file. Relative path names are
112           interpreted relative to the current directory. If this option is
113           not given, the default is plugin.ini in the plugin directory, where
114           plugin is the plugin argument on the command line.
115
116       ·   --print-defaults, -P
117
118           Display the default values from the configuration file. This option
119           causes mysql_plugin to print the defaults for --basedir, --datadir,
120           and --plugin-dir if they are found in the configuration file. If no
121           value for a variable is found, nothing is shown.
122
123           With mysql_plugin, this option need not be given first on the
124           command line, unlike most other MariaDB programs that support
125           --print-defaults.
126
127       ·   --verbose, -v
128
129           Verbose mode. Print more information about what the program does.
130           This option can be used multiple times to increase the amount of
131           information.
132
133       ·   --version, -V
134
135           Display version information and exit.
