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
