I created another thread for this but just realized this maybe the best
place to continue.  Is there anyway I can install rabbitmq in a box where
hostname is not resolvable. It will be resolvable in the future when it gets
to the client site but I need to install everything beforehand.  Also, when
the hostname is changed, I was going to enter in rabbitmq-env.conf

NODENAME=rabbit at newhostname
CONFIG_FILE=/etc/rabbitmq/rabbitmq

Is this all I need to do?  The first time I install rabbitmq, I remove the
guest user because I have separate authentication plugin to validate users. 
I see that when the new node name is assigned, system is trying to create
the guest user again.    Thank you.
