I have a pretty busy Cpanel CentOS server. It has some very important clients on it and I want to make a complete fail over server. I assume I will need to do this by purchasing another server, setting up hardware load balancing and then replicating and syncing the two servers.
Whats the best way to get a complete replication and syncing happening between the two servers? Basically, the idea is that if one of the servers goes down, the other server automaitcally picks up the slack and users dont notice any downtime whatsover. Neither do they need to make any configuration changes or lose any mail.
Ive never done something like this so I have no idea what the best options out there are, or if the solution our data center has recommended (with the ip load balancer) is the best. It has to be a solution for Cpanel.
