Here are my fileTemplateBundles for simplistic memcached mgmt in a RHEL/Centos/SL environment (the standard yum memcached install, I don't particularly like the standard rhel way, and would rather compiled standalone version in /usr/local, but short on time).
That is you can add/deregister (and remove via the "Purge" button) a cluster of up to 10 instances to whatever hosts you target.
There's a simple port checking tool that should be used in a Script server to figure out which ports to use.
Who needs containers when you have system mgmt?
Edit: re-uploaded process mgmt fixes.
Edit: added memcached restart bundle -- a two-liner that is the point of the whole exercise (revisited saltstack for this purpose but ran screaming once again).
Note: I now feel the unreg bundle is slightly flawed design -- it should be design to be wired directly to a destination directory and name extracted from rhq.deploy.dir -- see restart bundle for right idea.
