Make sure the hostnames of all the hosts resolve on all the hosts. You
may need entries in /etc/resolv.conf to achieve that.

The random port numbers used by the Erlang distribution framework change
each time the Erlang VM starts, so there is no value in recording them.
You could record the EPMD port or AMQP, but this is not required to set
up clustering.
