RabbitMQ + PHP Deployment Strategy

Question

I have a PHP project (Symfony2) that uses RabbitMQ. I use it as a simple message queue to delay some tasks (sending letters, important data from the API). Consumers run on a web server, and their code is part of the webserver repo - they are deployed along with the network.

Questions: How do I start consumers as demons and make sure they always work? When you deploy an application, how do you turn off consumers “gracefully” so that they stop consuming but finish processing the message that they started?

If this is important, I use Capifony for deployment.

Thanks!

It might be worth a look at something supervisord that is written in python. I used it before to run workers for Gearmand, which is a job queue that fully fulfills the same role as you use RabbitMQ.
