Apologies for the utter triviality of this question, but we all have to start somewhere! I've also tried searching but this question is pretty vague so I didn't (a) really know what to search for or (b) get many relevant hits to what I did search for.
Anyway, I'm in the process of self-teaching... (1 Reply)

rabbitmq-env.conf
RABBITMQ-ENV.CONF(5) RabbitMQ Server RABBITMQ-ENV.CONF(5)NAME
rabbitmq-env.conf - default settings for RabbitMQ AMQP server
DESCRIPTION
/etc/rabbitmq/rabbitmq-env.conf contains variable settings that override the defaults built in to the RabbitMQ startup scripts.
The file is interpreted by the system shell, and so should consist of a sequence of shell environment variable definitions. Normal shell
syntax is permitted (since the file is sourced using the shell "." operator), including line comments starting with "#".
In order of preference, the startup scripts get their values from the environment, from /etc/rabbitmq/rabbitmq-env.conf and finally from
the built-in default values. For example, for the RABBITMQ_NODENAME setting,
RABBITMQ_NODENAME
from the environment is checked first. If it is absent or equal to the empty string, then
NODENAME
from /etc/rabbitmq/rabbitmq-env.conf is checked. If it is also absent or set equal to the empty string then the default value from the
startup script is used.
The variable names in /etc/rabbitmq/rabbitmq-env.conf are always equal to the environment variable names, with the RABBITMQ_ prefix
removed: RABBITMQ_NODE_PORT from the environment becomes NODE_PORT in the /etc/rabbitmq/rabbitmq-env.conf file, etc.
# I am a complete /etc/rabbitmq/rabbitmq-env.conf file.
# Comment lines start with a hash character.
# This is a /bin/sh script file - use ordinary envt var syntax
NODENAME=hare

NODENAME=hare
This is an example of a complete /etc/rabbitmq/rabbitmq-env.conf file that overrides the default Erlang node name from "rabbit" to "hare".
