Yes, it is confusing. In short: Heartbeat is more or less "out of service". For the CentOS/RedHat distributions, you can follow the instructions at clusterlabs website :
http://www.clusterlabs.org/wiki/Install scroll down to "CentOS" etc. Instead of pacemaker + heartbeat this will end in a system with pacemaker and corosync, which is one of the currently supported setups. I have several "generic" recommendations: - Linux HA is not for the faint-hearted, you WILL experience unwanted things during your tests - you do your tests with a bunch of test servers, do you? (we use virtual servers for testing) - ignore old documentation referring to heartbeat. I invested some bucks into a current book on HA an think it was a good investment (make sure it includes OpenAIS and corosync) - use two different physical network connections for the HA "heartbeat", especially if you are DRBDing something. You must not risk a split-brain scenario in this case. - test, test, test. pull the plugs, overload one machine, misconfigure your application ...
