Replication can be set up to go bothways in a 2 server scenario for MySQL. This would solve your replication issue for 2 servers. More servers can be set up in a loop configuration for 3 or more servers. There is one problem with this method if one MySQL goes down updates are not passed around the loop. but as soon as the loop is reestablished the updates are passed around the loop to bring the other servers up to date. You might also consider DNS round robin to distribute initial connections to MySQL. A better solution is to use a load balancer that tracks to see if the servers are alive and balance against the load on each server. Cheers Max W.
