To change the RabbitMQ's listening port(s), add
   -rabbit tcp_listeners '[{"", 5673}]'
or similar to the RabbitMQ command line.

One place to do that is in the rabbitmq-server startup scripts. Either 
create one copy for each node or parameterise the script with an 
environment variable.

I'll add this info to our documentation.
