Why build it yourself? The app will do it for you, and not make a typo 
that could cost you valuable time. If you don't have X running on your 
nodes, no problem - just install the s-c-cluster app anywhere...it will 
let you configure a cluster and then save out the conf file which you 
can propogate to the cluster yourself, if you want.
