This was on CentOS 7.  I sort of suspect a hostname-related problem,
only because I've seen exactly this sort of behavior before due to
hostname issues (to which rabbitmq seems unusually sensitive).

For the record:

- the undercloud host boots up with the name "localhost.localdomain".

- I run "hostnamectl set-hostname stack.localdomain".

- I edit /etc/hosts and add "stack.localdomain" as an entry for

- After running instack-install-undercloud and having it explode
  because something is looking for "stack.localhost", I add that as an
  alias for as well.
