mon manager == my director?
you only need one director to load balance the connections
to your mysql realservers. You can set this up from the
command line using `ipvsadm`
be sure you understand the single writer, multiple reader
requirement for LVS, and the effect this has on writes to
databases when they operate inside an LVS. See the HOWTO.
If you want failover of the director, then you need two
directors. You can do this later when you are happy with the
load balancing.

heartbeat/Linux-HA/ldirectord is a package to failover
directors. It also helps setup the virtual services.
Another package which accomplishes the same thing is
keepalived.
