Hi Matthias,

Thanks for your reply.

Do you have any advice on how to (easily) set up such a configuration?
Trying to start multiple nodes on the same machine using only different
node names fails because each node tries to bind to the same port
(5672), which seems to be defined in ebin/rabbit.app. Since I am not
familiar with Erlang, it's not clear to me how I pass a different value
for the port when starting the node.
