Error 111 connecting to localhost:6379. Connection refused. Django Heroku

Question

I am able to run redis locally and everything works.

However when I deploy to heroku I get this error:

Error 111 connecting to localhost:6379. Conn         


        

Answer 1

Right now Heroku automatically sets the environment variable REDIS_URL to URL + port.

A convenient way to work with redis on heroku is to use a connection pool:

settings.py

import redis
REDIS_DEFAULT_CONNECTION_POOL = redis.ConnectionPool.from_url(os.getenv('REDIS_URL', 'redis://localhost:6379/'))

whererver.py

from redis import Redis
from myProject.settings import REDIS_DEFAULT_CONNECTION_POOL

redis = Redis(connection_pool=REDIS_DEFAULT_CONNECTION_POOL)
print(redis.keys())  # works
