- Red Hat Enterprise Linux (RHEL) 6 or 7 with the High Availability Add-On
Useful References and Guides
This guide offers Red Hat's policies and requirement around the management of
mysql databases by a RHEL High Availability cluster.
mysql releases and Red Hat resource-agents: Red Hat's
mysql resource-agents are developed with a target of managing the releases of this database server that are shipped as part of RHEL.
- RHEL 7:
mariadb-serverversion 5.5 is shipped in RHEL 7, and it is these version 5.5 releases that are targeted by the
mariadbresource agent for pacemaker clusters.
- RHEL 6:
mysql-serverversion 5.1 is shipped in RHEL 6, and it is these version 5.1 releases that are targeted by the
mysqlresource agents for
mysql releases: While Red Hat's agents may work with other non-RHEL
mysql releases, Red Hat cannot guarantee the behavior will be as expected, and does not test these combinations. It is up to the organization deploying any such combination to thoroughly test the operation of the agent being used and determine if it is adequate for that deployment's needs. In cases where Red Hat's
mysql resource agent is being used with a release of the database server other than what is shipped in that release of RHEL, Red Hat Support may be unable to assist with concerns relating to the agent's management of that release.
Using 3rd party or custom agents or scripts: In situations where Red Hat's agent is not adequate for managing the
mysql server(s) deployed on a cluster, customer organizations may wish to develop their own scripts or agents, or some 3rd party may offer a script or agent for this purpose. Red Hat's typical policy on 3rd-party or custom agents or scripts applies here.
