This section describes how to install and uninstall the
        validate_password password-validation
        component. For general information about installing and
        uninstalling components, see Section 7.5, “MySQL Components”.
          If you install MySQL 8.0 using the
          MySQL Yum
          repository,
          MySQL SLES
          Repository, or
          RPM packages provided
          by Oracle, the validate_password
          component is enabled by default after you start your MySQL
          Server for the first time.
        
          Upgrades to MySQL 8.0 from 5.7
          using Yum or RPM packages leave the
          validate_password plugin in place. To make
          the transition from the validate_password
          plugin to the validate_password component,
          see Section 8.4.3.3, “Transitioning to the Password Validation Component”.
        To be usable by the server, the component library file must be
        located in the MySQL plugin directory (the directory named by
        the plugin_dir system
        variable). If necessary, configure the plugin directory location
        by setting the value of
        plugin_dir at server startup.
      
        To install the validate_password component,
        use this statement:
      
INSTALL COMPONENT 'file://component_validate_password';
        Component installation is a one-time operation that need not be
        done per server startup. INSTALL
        COMPONENT loads the component, and also registers it
        in the mysql.component system table to cause
        it to be loaded during subsequent server startups.
      
        To uninstall the validate_password component,
        use this statement:
      
UNINSTALL COMPONENT 'file://component_validate_password';
        UNINSTALL COMPONENT unloads the
        component, and unregisters it from the
        mysql.component system table to cause it not
        to be loaded during subsequent server startups.
