There are several how-to's already on the site, but each addresses only a single component of a LAMP server. It would be great to see a how-to that shows how to setup a complete LAMP cluster, perhaps with a mail server incorporated into it. Chris
i agree. i would like to see something like this aswell. than with: 1 server for apache + php 1 server for mysql 1 server for mail 1 load balancer and one that binds it all together (could be the load balancer server) so 4 or 5 servers in total. perhaps also a file server i'm having a idea on how to install this.. all the server need to have heartbeat and the loadbalancer needs to check who's available. but i don't know how you can connect all those servers and make it look like 1 big server.. BTW. MySQL can be made as a real cluster. apache can't (correct me if i'm wrong). edit what would this be: http://www.linux.com/articles/53578 it's interesting. and exactly what your looking for.
MySQL, setup as a master-master replicator can do high availability clustering quite well. Todo the websites, use rsync between the two machines, and then use Heartbeat to manage the shared IP between the two machines
