Dear Centos users,
I am not sure if this the correct place to post but it seems sensible.
I have an 8 node cluster which I want to install/configure Centos. As
I am not a sys-admin, can anyone advise me on what I should do?
Any suggestions appreciated.
Thank you.

First;
What kind of cluster? There are as many clusters as there are problems.
Second;
Be prepared to spend a lot of time learning. Clusters are generally
not simple things and require a fair bit of understanding to maintain
properly. It is not inherently difficult, but it is quite involved. If
you are not in a position to learn this yourself, find and retain a
cluster admin.
Third;
Assuming you want a high-availability cluster, start be reading up on
Corosync and Pacemaker. The former provides cluster communication, the
latter provides resource management.
Finally;
There is a good clustering mailing list at
https://www.redhat.com/mailman/listinfo/linux-cluster

What do you mean by "cluster"? Is this for high-availability (H/A), or
load balancing for very heavy traffic, or high performance computing? Each
is different.

Google centos cluster configuration howto
Hit 1:
http://www.linuxtopia.org/online_books/centos_linux_guides/centos_cluste
r_configuration_and_management/index.html
This is a Table of Contents to a (fairly extensive) web tree all about
configuring and managing a Red Hat cluster suite.
Hit 2 is one of the pages in Hit 1
Other hits provide information that looks pretty comprehensive.

Hi !
What kind of cluster ? Is it for high-availibity ? Will there be shared
storage ?
I got with the same questions in the past monthts, and you can take a look
at the doc :
These are from the Upstream vendor's and that is what's included with CentIS
5.5 (sson to be 5.6). CentOS 6 isn't out yet, but should be in the following
months.
You can also subscribe to the linux-cluster list :
If you're not a sys-admin, you will probably need to get one to administer
such cluster.
Regards,

First things first, are you thinking of a compute cluster or a service/HA one?

Or, these days there is even a category of distributed databases like
riak that work across a group of machines, and only the app needs to be
set up for clustering.

Configuring a cluster
Dear all,
Thank you very much for your answers; am a little overwhelmed as I did
not expect so many so fast. I will take a look at your suggestions and
sites.
The cluster is medium performance for something called bioinformatics;
we are looking at next generation sequence data.
I know it had Centos installed and was using Torque/PBS for running
cluster jobs. This was set up by a company and we want to install
fresh.
If I get anywhere without a sys admin, I will post (maybe another question).
Cheers,

*chuckle* I was thinking you didn't realize how many kinds there were.

Um, right. I think you need to email me, offlist: the gov't agency I work
for does just that, and I'm one of a team of three that supports just that
environment.

What you describe here is quite clearly a compute cluster, HPC, or whatever
you want to call it.
Maybe you should go have a look at a packaged solution like rocks
(www.rocksclusters.org). If you don't have much experience I'd recommend
against building something yourself. With rocks you'll also get the benefit of
prepackaged bio-informatics stuff (rocks has a large community).
