[rabbitmq-discuss] Automated deployment of rabbit and clustering.

Thu Sep 5 11:47:14 BST 2013

In your example you have:

[{rabbit,
  [{cluster_nodes, {['rabbit at rabbit1', 'rabbit at rabbit2',
'rabbit at rabbit3'], disc}}]}].

What we do is just leave it like that and have a separate part of the
automated install which sets /etc/hosts to resolve those names.
