Hi there. The node name is set by the scripts rabbitmq-server and 
rabbitmqctl.

Erlang has two kinds of node name, short names (passed as -sname <name> 
to the emulator) and long names (pass as -name <name>). Short names must 
not contain the full hostname, whereas long names do. For example here 
is one short and one long name:

$ erl -sname myserver
$ erl -name myserver.mydomain.com

By default, rabbit uses the 'shortnames' scheme. The actual name that a 
node uses is governed by the environment variable RABBITMQ_NODE_NAME, 
and by default this will be set to 'rabbit'.

Both the scripts need to use the same naming scheme. If you're using the 
default (short) naming scheme, then your node names must not contain the 
domain part, just the 'short' hostname as evidenced via `hostname -s` or 
equivalent.
