airtime-celery
==============
airtime-celery is a Celery_ daemon for handling backend tasks asynchronously.
Communication and the Celery results backend are both handled with amqp (RabbitMQ).
Installation
============
$ sudo python setup.py install
To install the configuration and upstart files for all environments (development and production)
$ sudo python setup.py install --all-envs
You can also specify a single environment to deploy config and upstart files for:
$ sudo python setup.py install --dev-env=bananas
Each instance of airtime-celery has its own worker, and multiple instances can be run in parallel.
`Celery is thread-safe`_, so this parallelization won't cause conflicts.
.. _Celery: http://www.celeryproject.org/
.. _Celery is thread-safe: http://celery.readthedocs.org/en/latest/userguide/application.html
Usage
=====
This program must be run with sudo:
$ sudo service airtime-celery {start | stop | restart | graceful | kill | dryrun | create-paths}
Developers
==========
You may want to use the setuptools develop target to install:
$ sudo python setup.py develop
You will need to allow the "airtime" RabbitMQ user to access all exchanges and queues within the /airtime vhost:
$ sudo rabbitmqctl set_permissions -p /airtime airtime .\* .\* .\*
Logging
=======
By default, logs are saved to:
/var/log/airtime/airtime-celery[-DEV_ENV].log
