[rabbitmq-discuss] Running RabbitMQ as a different user

[Matt Pietrek]

Thanks Jason.

That's helpful, but in my admittedly limited knowledge, I don't believe that
it's as simple as that. In particular I don't understand how handle files
being installed with rabbitmq as the owner.

A little more context that I forgot to mention earlier:
* I need to cluster multiple nodes so explicitly specifying the cookie is
necessary so they're synced. Also, specifying the cookie via an environment
variable is preferred to having an additional cookie file that I need to
copy to multiple machines.
* I need to be able to launch everything from scratch via my own script file
(which will be on all nodes.)
My current thinking is that my startup script will set some RABBITMQ
environment variables (RABBITMQ_CONFIG_FILE, RABBITMQ_SERVER_START_ARGS,
RABBITMQ_CTL_ERL_ARGS,). The script will then directly run rabbit-server in
/usr/lib/rabbitmq/bin. Also, RABBITMQ_CONFIG_FILE will point to the
rabbitmq.config file that I've dropped on all nodes to set up auto
clustering.)

Thanks again,

Matt
