The best thing I can do at this time is point you to my *incomplete* 
How-To I was working on for CentOS. It's not perfect, it's not even 
vetted. In fact, I've set it aside and have started re-working it for 
Fedora 13 at this time, with the goal of eventually re-writing it again 
for CentOS 6.

With that convoluted warning and caveat, take a look at this:


The work-in-progress Fedora 13 variant is here:


The CentOS original document will not be completed any further than it 
is. I've decided to move away from the old cluster stack. The Fedora 
variant is very actively being developed (I put a couple hours into each 
night) as is not really safe to follow.

This makes it hard for me to recommend an operating system to base your 
cluster on. Obviously, you want the stability of a server-class 
operating system like CentOS. However, you'll be working hard to get an 
old-fashioned cluster off the ground. As such, I will leave that 
decision up to you.

As for a roadmap - No one can give you that. No two clusters are the 
same. They are designed to solve a particular problem. What I can give 
is advise;

Answer these questions:

1) What problems are you trying to solve with a cluster.

2) What research have you done that concludes that a cluster will 
introduce fewer problems than it solves.

3) Are you prepared to learn and then maintain the cluster?

4) Are you willing and able to take the time to throughly test and debug 
your cluster before going live? Do not expect to get your cluster live 
in anything less than a month's time.

Clustering is not something you can briefly jump into and then move on from.
