Setting up a cluster

Hi

Im currently trying to learn how to set up a cluster. What would like to know how to set up is a web server cluster with three servers and the domain would be something like example-www.mydomain.com where the three servers would be example-www01.myomain.com and so on. Ive searched on google, but cannot really find any good guides.

There are different kind of clusters.
High Availability/Failover:
When the main site goes down, the backup site becomes active and so on. With this kind of cluster the linux-ha (google) project is helpful.

Load Balancing:
Hits are being distributed between the web servers so that they all share the load. In OpenBSD PF you can configure load balancing easily and it's probably quite easy in GNU/Linux too but I have no real experience with this.

Perhaps if you tell us what kind of cluster you want to build, we can help you more.
