-l, --loglevel¶

Logging level, choose between DEBUG, INFO, WARNING, ERROR, CRITICAL, or FATAL.

-p, --pidfile¶

-s, --statistics¶

Turn on reporting of statistics (remember to flush the statistics message queue from time to time).

--discard¶

celery.bin.celeryd.acquire_pidlock(pidfile)¶

Get the daemon.pidlockfile.PIDLockFile handler for pidfile.

If the pidfile already exists, but the process is not running the pidfile will be removed, a "stale pidfile" message is emitted and execution continues as normally. However, if the process is still running the program will exit complaning that the program is already running in the background somewhere.

celery.bin.celeryd.parse_options(arguments)¶

Parse the available options to celeryd.

celery.bin.celeryd.run_worker(concurrency=0, detach=False, loglevel=20, logfile='celeryd.log', discard=False, pidfile='celeryd.pid', umask=0, uid=None, gid=None, working_directory=None, chroot=None, statistics=None, **kwargs)¶

Starts the celery worker server.
