Install the Audit Log Filter

The feature is in tech preview.

The plugin_dir system variable defines the plugin library location. If needed, at server startup, set the plugin_dir variable.

When upgrading a MySQL installation, plugins are not automatically upgraded. You may need to manually load the plugin after the MySQL upgrade.

In the share directory, locate the audit_log_filter_linux_install.sqlscript.

Implemented in 8.0.34, at the time you run the script, you can select the database used to store the JSON filter tables.

• If the plugin is loaded, the installation script takes the database name from the audit_log_filter_database variable
• If the plugin is not loaded, but passes the -D db_name to the mysql client when the installation script runs, uses the db_name.
• If the plugin is not loaded and the -D option is not provided, the installation script creates the required tables in the default database name mysql.

You can also designate a different database with the audit_log_filter_database system variable. The database name cannot be NULL or exceed 64 characters. If the database name is invalid, the audit log filter tables are not found.

With 8.0.34 and higher, use this command:

$ mysql -u -D database -p < audit_log_filter_linux_install.sql

To verify the plugin installation, run the following command:

mysql> SELECT PLUGIN_NAME, PLUGIN_STATUS FROM INFORMATION_SCHEMA.PLUGINS WHERE PLUGIN_NAME LIKE `audit%';

Expected output

+--------------------+---------------+
| PLUGIN_NAME        | PLUGIN_STATUS |
+--------------------+---------------+
| audit_log_filter   | ACTIVE        |
+--------------------+---------------+

After the installation, you can use the --audit_log_filter option when restarting the server. To prevent the server from not running the plugin use --audit_log_filter with either the FORCE or the FORCE_PLUS_PERMANENT values.
