Django celery: Consumer Connection Error (111) when running python manage.py celeryd

Question

I am trying to configure a Django project to use Celery (I am using Django 1.3 on Debian Squeeze)

I installed django-celery (2.3.3) and then followed these instructions.

My django celery settings are the following:

BROKER_HOST = "localhost"
BROKER_PORT = 5672
BROKER_USER = "guest"
BROKER_PASSWORD = "guest"
BROKER_VHOST = "/"

When I try to launch the celery worker server with...

$ python manage.py celeryd -l info

I get the following output with a "Consumer: Connection Error: [Errno 111]" at the end :

/home/thomas/virtualenv/ULYSSE/lib/python2.6/site-packages/djcelery/loaders.py:84:     UserWarning: Using settings.DEBUG leads to a memory leak, never use this setting in production environments!

Apparently, my settings are correctly read (cf. Configuration section in the output) and the worker process is correctly started ("celery@debian has started")

I can not figure out why this "Consumer: Connection Error: [Errno 111]" error appends...

Has this to do with the BROKER_USER and BROKER_PASSWORD settings?

I tried different settings for user/password (my account, root account...) but I always get the same error. Does 'BROKER_USER' and 'BROKER_PASSWORD refer to a OS user, a database user, a "broker" user?

How can I get rid of this Connection Error?

Looks like rabbitmq isn't installed or running. Can you check this?

apt-get install rabbitmq-server 

on Ubuntu
