I don't use apache, so I can't speak to that resource agent's config. I
can say though that overall it looks okay with two exceptions.
You *must* configure fencing for the cluster to work properly. Even
without shared storage, a node failure will trigger a fence call which,
because it can't succeed, will leave your cluster hung hard.
Change the cluster names to the output of `uname -n` (should be the FQDN).
