MySQL 8.0 Source Code Documentation
This section describes sources of information about keyring use.
To see whether a keyring plugin is loaded, check the Information
Schema PLUGINS table or use the
SHOW PLUGINS statement (see
Section 7.6.2, “Obtaining Server Plugin Information”). For example:
mysql> SELECT PLUGIN_NAME, PLUGIN_STATUS
FROM INFORMATION_SCHEMA.PLUGINS
WHERE PLUGIN_NAME LIKE 'keyring%';
+--------------+---------------+
| PLUGIN_NAME | PLUGIN_STATUS |
+--------------+---------------+
| keyring_file | ACTIVE |
+--------------+---------------+
To see which keys exist, check the Performance Schema
keyring_keys table:
mysql> SELECT * FROM performance_schema.keyring_keys;
+-----------------------------+--------------+----------------+
| KEY_ID | KEY_OWNER | BACKEND_KEY_ID |
+-----------------------------+--------------+----------------+
| audit_log-20210322T130749-1 | | |
| MyKey | me@localhost | |
| YourKey | me@localhost | |
+-----------------------------+--------------+----------------+
To see whether a keyring component is loaded, check the
Performance Schema
keyring_component_status table. For
example:
mysql> SELECT * FROM performance_schema.keyring_component_status;
+---------------------+-------------------------------------------------+
| STATUS_KEY | STATUS_VALUE |
+---------------------+-------------------------------------------------+
| Component_name | component_keyring_file |
| Author | Oracle Corporation |
| License | GPL |
| Implementation_name | component_keyring_file |
| Version | 1.0 |
| Component_status | Active |
| Data_file | /usr/local/mysql/keyring/component_keyring_file |
| Read_only | No |
+---------------------+-------------------------------------------------+
A Component_status value of
Active indicates that the component
initialized successfully. If the component loaded but failed to
initialize, the value is Disabled.
