Just to comment, it took me about an hour to set up (the latest at the
time) rabbitmq on CentOS 5.  I wrote a blog post about it here, maybe
it'll be helpful:

You can ignore the whole new project part, but installing rabbitmq
itself is fairly straightforward.
For management, there's Alice:

Apparently, with the new persister, rabbitmq can save messages to disk
before any crashes.  You can read more about it here:

However, I personally use a backup message storing system (PostgreSQL)
and redeliver undelivered messages (my queues are not durable.)  This
however makes for extra code.

Others might provide more insight, but that's my 2 cents from my
particular usage case.
