In this release, we added support for a new Linux distribution.

Use OpenSUSE 15/SUSE Linux Enterprise Server 15 with ClusterControl.

OpenSUSE is an open-source community project with Linux-based distributions sponsored by SUSE Software Solutions Germany GmbH and other companies.

SUSE Linux Enterprise Server (SLES) receives more intense testing than the upstream OpenSUSE community distro, intending that only mature, stable versions of packages will make it through to SLES.


OpenSUSE 15/SUSE Linux Enterprise Server 15

  • Support for:
    • MariaDB Server v10.x with mariabackup (Xtrabackup is not available)
    • MariaDB Galera Cluster v10.x with mariabackup (Xtrabackup is not available)
    • PostgreSQL v10+
    • MySQL NDB Cluster
    • HAProxy on OpenSUSE only
  • Current limitations:
    • ProxySQL is currently not supported
    • HAProxy is currently only supported on OpenSUSE
    • Co-located PostgreSQL nodes is not supported
    • TimescaleDB is not supported on OpenSUSE/SLES
    • Oracle MySQL Replication is not supported
