In MySQL 8.3, the
validate_password plugin was reimplemented
validate_password component. The
validate_password plugin is deprecated;
expect it to be removed in a future version of MySQL.
MySQL installations that currently use the
validate_password plugin should make the
transition to using the
component instead. To do so, use the following procedure. The
procedure installs the component before uninstalling the plugin,
to avoid having a time window during which no password
validation occurs. (The component and plugin can be installed
simultaneously. In this case, the server attempts to use the
component, falling back to the plugin if the component is
INSTALL COMPONENT 'file://component_validate_password';
validate_passwordcomponent to ensure that it works as expected. If you need to set any
validate_password.system variables, you can do so at runtime using
SET GLOBAL. (Any option file changes that must be made are performed in the next step.)
Adjust any references to the plugin system and status variables to refer to the corresponding component system and status variables. Suppose that previously you had configured the plugin at startup using an option file like this:
[mysqld] validate-password=FORCE_PLUS_PERMANENT validate_password_dictionary_file=/usr/share/dict/words validate_password_length=10 validate_password_number_count=2
Those settings are appropriate for the plugin, but must be modified to apply to the component. To adjust the option file, omit the
--validate-passwordoption (it applies only to the plugin, not the component), and modify the system variable references from no-dot names appropriate for the plugin to dotted names appropriate for the component:
[mysqld] validate_password.dictionary_file=/usr/share/dict/words validate_password.length=10 validate_password.number_count=2
Similar adjustments are needed for applications that refer at runtime to
validate_passwordplugin system and status variables. Change the no-dot plugin variable names to the corresponding dotted component variable names.
UNINSTALL PLUGIN validate_password;
validate_passwordplugin is loaded at server startup using a
--plugin-load-addoption, omit that option from the server startup procedure. For example, if the option is listed in a server option file, remove it from the file.
Restart the server.
