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
