In MySQL 8.0.4, the
plugin was reimplemented as the
validate_password component. The
validate_password plugin is deprecated and
will 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 you configure 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
To adjust the option file, omit the
--validate-passwordoption (it applies only to the plugin, not the component), and modify the system variable references:
[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.
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.
