Pretty much the standard thing to do is use a virtual IP address with ucarp
handling reassignment if the primary node goes down. I've yet to run that
through thorough tests to see if how transparent it is in a case of failure.
It's simple to set up though.

There are, of course, plenty of more complicated alternatives to ucarp in
the HA world - heartbeat, pacemaker, corosync....
