Short answer:
Install two servers and call them cluster. Easy and fast success.

At least share if you want to have a cluster like compute farm or something distributed or hihly available, and most importantly - give an idea on what application you will be running on the cluster.

Hi

gheist is right, you need to know your requirements for a cluster and the resources it is making resilient.

For starters take a look at http://www.linux-ha.org/wiki/Main_Page this will get you a starter for 10.  I found the heartbeat solution an easy one to configure, especially if resource requirements are minimal.

At minimum for the heartbeat solution you need to install the heartbeat package(s) then;

1. Put an additional NIC in each server with a crossover cable for the node heartbeat.
2. Configure IP address aliasing
3. Decide what services you want to make resilient and define this in the heartbeat config files (ha.conf/haresources from memory, there could be more)
4. Start the hearbeat daemon

Cheers, P

Cluster is not always about resilience.
No-single-point-of-failure is a good start for a blueprint.
