Fireup all our nodes.

I could find information about this only which was odd. The tutorial is nice if you are setting up some static site ala the early 00's.
So this is some notes on creating a cluster by hang which will feed into the creation of a puppet / ansible / chef / shell / slat script 
to do the main part of creating the cluster. 

I note also many clients do not support redis in cluster mode WTF?

Selinux can be difficult when you just want it to work and many people just switch it off
Here is something simple command lines I use to just set it up, its best to go away for a week and learn it all properly but this is good when you just want to get it done.

yum install policycoreutils-python # Centos package

NOTE: all changes take effect and remain even after a reboot

Allow something to execute / write to a file / area
     # find type name 1st ( this may prove more difficult in which case look at agent logs)
     semanage fcontext -l | grep progname
