Mon + LVS for a mysql cluster

[Romain Moyne <aero_climb@xxxxxxxx>]

Hello,
I'm sorry for my bad english... ;)
I want to build a high availability cluster for MySQL servers. I believe 
I can use LVS.
I would have one loadbalancer and 3 mysql servers (the nodes) for 
example. But if a mysql daemon dies, i want that the loadbalancer knows 
this and that it doesn't redirect the (mysql) queries to this node. I 
think it's possible to do this with Mon.  Did somebody  install  a such 
system?
Thanks you for your answers,
Romain ;)
