The ip is the internal ip of the VM.

[ {rabbit, [ {tcp_listeners, [{"127.0.0.1", 5672}, {"::1", 5672}, {"10.249.30.196", 5672} ]} ]} ].

TODOS

if a node fails, take a look at how to restart it, also you can restart the rabbit server with

• sudo /etc/init.d/rabbitmq-server start but only when you NEED to do it, otherwise is better to use stop_app and start_aop
