In production environments, you need to configure the application through environment variables as well. There are many ways to do this: Webserver config, startup script, wsgi file, virtualenv loaders, etc.
The env variables also must be set when running the celery worker daemon. Make sure that debugging is turned off in your production configuration.
Provisioning a production system
In order to deploy the application in a prodcution environment, you need to provision your deployment machine accordingly. There are severals ways to do this automatically with tools like `Puppet`_ or Chef. You can of course do this manually as well.
In order to run the Celery deamon on your production site, please use the generic init/upstart script provided with celery. For more information see the `daemonizing`_ chapter of the Celery documentation or refer to your devops people ;)
In order to use meshlab, you also need a running X11 instance or xvfb as DISPLAY number 99 if you are running a headless setup (the display number can be overridden in you config file). Plese refer to your Linux distribution of how to setup xvfb.
There's an nice tool called Flower to graphically manage and monitor the celery task queue. We highly recommend it for debugging purposes on the production system. It has been installed with the requirement.txt loading business above. So you should be ready to go. Please refer to the Flower manual for more information.
