Celery tries to connect to the wrong broker

Question

I have in my celery configuration

BROKER_URL = 'redis://127.0.0.1:6379'
CELERY_RESULT_BACKEND = 'redis://127.0.0.1:6379'

Yet whenever I run the celeryd, I get this error

consumer: Cannot connect to amqp://guest@127.0.0.1:5672//: [Errno 111] Connection refused. Trying again in 2.00 seconds...

Why is it not connecting to the redis broker I set it up with, which is running btw?

Answer 1

import your celery and add your broker like that :

celery = Celery('task', broker='redis://127.0.0.1:6379')
celery.config_from_object(celeryconfig)

Answer 2

If you followed First Steps with Celery tutorial, specifically:

app.config_from_object('django.conf:settings', namespace='CELERY')

then you need to prefix your settings with CELERY, so change your BROKER_URL to:

CELERY_BROKER_URL = 'redis://127.0.0.1:6379'

Answer 3

I got this response because I was starting my celery worker incorrectly on the terminal.

I was running:

celery -A celery worker

But because I defined celery inside of web/server.py, I needed to run:

celery -A web.server.celery worker

web.server indicates that my celery object is in a file server.py inside a directory web. Running that latter command connected to the broker I specified!
