Indeed. In your /etc/rabbitmq/rabbitmq.conf, add the line:

NODENAME=rabbit at localhost

This will force Erlang to not look at your hostname when trying to
determine its node name, and instead will use localhost. Note though
that this means the *Erlang node* is not contactable via a different
machine (i.e. you couldn't use rabbitmqctl from a different machine, or
do clustering). Also node it does not stop *Rabbit* from listening on
public interfaces. If you want to make sure Rabbit only listens to
127.0.0.1 then add a further line to your rabbitmq.conf:

NODE_IP_ADDRESS=127.0.0.1

I hope that's of help.
