I've been tasked with setting up some sort of redundancy/fail over for a
smallish company. The setup will be 2 servers in different datacentres -
both running debian and serving up mysql driven sites on apache2,
probably some rails stuff too, if thats important. I've done a bit of
reading and it seems a lot of solutions are geared towards having a
single front end server directing requests to multiple backend servers,
but I'm trying to achieve something so that if server A is down, request
goes to server B, presumably this would have to use round robin dns?
And obviously this requires servers A and B to be completely in sync,
mysql replication? rsync? unison?
Am I going about this the right way? if so, is round robin dns and mysql
replication sufficient? If not, any advice?
