MySQL 8.4 Reference Manual  /  ...  /  Obtaining Server Plugin Information

7.6.2 获取服务器插件信息

There are several ways to determine which plugins are installed in the server:

  • The Information Schema PLUGINS table contains a row for each loaded plugin. Any that have a PLUGIN_LIBRARY value of NULL are built in and cannot be unloaded.

    mysql> TABLE INFORMATION_SCHEMA.PLUGINS\G
    *************************** 1. row ***************************
               PLUGIN_NAME: binlog
            PLUGIN_VERSION: 1.0
             PLUGIN_STATUS: ACTIVE
               PLUGIN_TYPE: STORAGE ENGINE
       PLUGIN_TYPE_VERSION: 80100.0
            PLUGIN_LIBRARY: NULL
    PLUGIN_LIBRARY_VERSION: NULL
             PLUGIN_AUTHOR: Oracle Corporation
        PLUGIN_DESCRIPTION: This is a pseudo storage engine to represent the binlog in a transaction
            PLUGIN_LICENSE: GPL
               LOAD_OPTION: FORCE
    *************************** 2. row ***************************
               PLUGIN_NAME: mysql_native_password
            PLUGIN_VERSION: 1.1
             PLUGIN_STATUS: ACTIVE
               PLUGIN_TYPE: AUTHENTICATION
       PLUGIN_TYPE_VERSION: 2.1
            PLUGIN_LIBRARY: NULL
    PLUGIN_LIBRARY_VERSION: NULL
             PLUGIN_AUTHOR: Oracle Corporation
        PLUGIN_DESCRIPTION: Native MySQL authentication
            PLUGIN_LICENSE: GPL
               LOAD_OPTION: FORCE
    ...
  • The SHOW PLUGINS statement displays a row for each loaded plugin. Any that have a Library value of NULL are built in and cannot be unloaded.

    mysql> SHOW PLUGINS\G
    *************************** 1. row ***************************
       Name: binlog
     Status: ACTIVE
       Type: STORAGE ENGINE
    Library: NULL
    License: GPL
    *************************** 2. row ***************************
       Name: mysql_native_password
     Status: ACTIVE
       Type: AUTHENTICATION
    Library: NULL
    License: GPL
    ...
  • The mysql.plugin table shows which plugins have been registered with INSTALL PLUGIN. The table contains only plugin names and library file names, so it does not provide as much information as the PLUGINS table or the SHOW PLUGINS statement.
