MySQL 8.0 Reference Manual  /  ...  /  Password Validation Component Installation and Uninstallation

6.5.3.1 Password Validation Component Installation and Uninstallation

This section describes how to install and uninstall the validate_password password-validation component. For general information about installing and uninstalling components, see Section 5.5, “MySQL Server Components”.

Note

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 6.5.3.3, “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, set the value of plugin_dir at server startup to tell the server the component directory location.

To install validate_password, 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 validate_password, use this statement:

UNINSTALL COMPONENT 'file://component_validate_password';

UNINSTALL COMPONENT unloads the component, and deregisters it from the mysql.component system table to cause it not to be loaded during subsequent server startups.
