RabbitMQ does not only run on Linux and could be better described as a
multiplatform Erlang service than a linux daemon.

RabbitMQ cannot report its own version without starting up. Once the
broker has started up up you can determine the version number using
"rabbitmqctl status", which will report the versions of all running
Erlang applications under "running_applications".

You will also find the version reported in the startup banner (typically
/var/log/rabbitmq/startup_log) after starting up.

If you want to query the version without starting up the broker, and you
installed RabbitMQ from a package, then you could query your package
manager for the version.
