has the overview of the infrastructure. Step-by-step installation might
be too long for a mailing list, but the idea is the same as installing
anything under RHCS -- so any tutorial will help you that describes how
to configure a clustered service in RHCS. Please note that this is not
an active-active system as you wrote above, so those clusters won't
apply this. Another tip would be keeping lock file and pid in the shared
storage, not on the local disks. You will need to adjust init scripts
for that, too. There is not too much manual work btw.
Oh, that reminds me -- RHCS is currently using cman+corosync+rgmanager,
so any solutions with pacemaker will work, but won't be supported by Red
Hat (though AFAIK RHEL 7 will use pacemaker by default)
Feel free to use luci and ricci for configuring the services, they will
help you a lot. Luci is the web interface for configuring cluster, ricci
is the agent on each node.
