CentOS - Feb 2011 - Configuring a cluster

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:

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 :

http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Cluster_Suite_Overview/index.html

http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Cluster_Administration/index.html

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 :

http://www.redhat.com/mailman/listinfo/linux-cluster

This list is very friendly and very centos-open.

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?
