This feature is introduced in version 1.6.2.
Consolidates cluster-wide security functionality on an easily accessible single page. In the previous versions, the cluster-wide security configuration fell under MySQL’s Cluster Actions menu. Supported security functionalities are:
- Client/Server SSL encryption for MySQL/MariaDB-based clusters.
- SSL replication traffic encryption for MySQL/MariaDB Galera-based clusters.
- Audit Logging
There is currently under development functionality for MySQL:
- Transparent Data Encryption, also known as Data-at-Rest Encryption
SSL Encryption
Enable
Enables encrypted SSL client-server connections for the database node(s). The transport layer will be encrypted using the Transfer Layer Security (TLS) protocol. The same certificate will be used on all nodes and to enable SSL encryption the nodes must be restarted. Select ‘Restart Nodes’ to perform a rolling restart of the nodes. All keys and certificates will be generated using OpenSSL.

Change Certificate
Changes the existing certificate for SSL client-server connections for the database node(s). This feature is only available if you already enabled SSL encryption for this cluster. It loads the same options as mentioned in Create Certificate and Use Existing Certificate respectively.
Disable
Disables SSL encryption for the cluster. This option is only available if you have enabled SSL encryption.
Galera SSL Encryption
Enable
Exclusive for Galera Cluster. This feature configures Galera replication to use SSL instead of plain replication between Galera nodes. The SSL key and certificate will be created on the Galera nodes. During this operation, the cluster will be stopped and started again.
Create Certificate
- Certificate expiration
- A number of days before the certificate become expired and invalid. Default is 1 year (365 days).
Use Existing Certificate
- Selected Certificate
- Pick an exiting certificate, stored by Key Management.
Change Certificate
Changes the existing certificate for Galera replication SSL connections. This feature is only available if you already enabled Galera SSL encryption for this cluster. It loads the same options as mentioned in Create Certificate and Use Existing Certificate respectively.
Disable
Disables Galera SSL encryption for the cluster. This option is only available if you have enabled Galera SSL encryption.
Audit Log
Enable
Only for MariaDB-based clusters. Enable Audit Logging on MariaDB-based clusters using policy-based monitoring and logging of connection and query activity. This feature will enable audit logging on all nodes in the cluster.

Starting from ClusterControl 1.9.7 (September 2023), ClusterControl GUI v2 is the default frontend graphical user interface (GUI) for ClusterControl. Note that the GUI v1 is considered a feature-freeze product with no future development. All new developments will be happening on ClusterControl GUI v2. See User Guide (GUI v2).
