I am trying to get Celery work for awhile now. All my crontabs works just fine when I test it synchronously
sudo celery -A testdjango worker --loglevel=DEBUG --beat
but when I do
celery multi start -A testdjango w1 -l info
none of my crontabs work. I am not sure why
Note: I tried other schedule intervals as well like with time delta
The same thing happens with that as well.
So I am fairly certain this is not a crontab thing but somehow related to the way I am starting celery multi.
Also, the worker turns on just fine since I can see it in Celery Flower but no tasks get executed.
So, the answer is pretty straightforward
Since periodic tasks need Beat just add --beat with the command.
something like this
celery multi start -A testdjango w1 --beat -l info
Alternatively instead of running Beat inside your worker process (which the docs for 3.1.18 say is not recommended) you can run it dedicated in the background with
celery beat -A testdjango --pidfile=/blah/beat.pid --detach
Be sure to save the pidfile somewhere so you can also kill the process later.
