HA cluster question


Hello, I just wanted to know if I can configure HA on 2 machines so when one machine dies the other will execute a specific command for me.

If so, where in the ha config can I do this?

True HA requires a minimum of 3 machines. What HA do you plan to use? More details would help someone give you the information you need or at least point you in the right direction to find the information you need.

Basically all I want to do is create redundancy between 2 servers for mail, mysql and apache... And for it not to be too dificult to setup and maintain. These services will be on an openvz virtualized container on both boxes, so I figured maybe just rsync the 2 boxes (not sure if that would work correctly with mail and sql) then if 1 box dies HA recognizes this and executed a cmd to start the other vm, if that makes any sense.

Any other suggestions are welcomed.

I recommend searching and reading some guides and do one thing, if that work, move to the other. Check this guides and hope it helps http://www.howtoforge.com/set-up-a-loadbalanced-ha-apache-cluster-ubuntu8.04and http://it.toolbox.com/wiki/index.php/Debian_HA_MySQL_Servers_with_Heartbeat
