If you only want a single director, you don't need heartbeat,

Heartbeat provides High Availability of a given service (in this case,
the load balancer and VIP). The clue is in the name of the project
providing heartbeat - Linux-HA.

Ldirectord provides load balancing between a number of servers (in this
case your database servers). It's the Linux Director Daemon (or Load
Director Daemon, to borrow terminology from a commercially available
hardware platform).

If you only have a single server participating in your HA setup, it's
not HA :)

Forget heartbeat.
