How to correctly use celery

[tanyewei]

I have modified the default celery configuration

BROKER_TRANSPORT = 'redis'
CELERY_BROKER_URL = 'redis://172.16.222.238:6379/5'
CELERY_RESULT_BACKEND = 'redis://172.16.222.238:6379/5'
CELERY_TASK_SERIALIZER = 'json'
CELERY_DISABLE_RATE_LIMITS = True
CELERY_ACCEPT_CONTENT = ['json', ]
CELERY_IMPORTS = ('app.tasks',)

OperationalError: Error 61 connecting to localhost:6379. Connection refused.

This template seems create 2 celery instances, one in extensions.py, and one in celery_run.py, which may result of celery not recevie tasks send by application.
