How to get Redis to start on Heroku?

Are you using Resque? If so, you'll need to tell Resque which Redis to use.

Resque.redis = REDIS

If not, then the code you've posted about is NOT setting your REDIS connection up.

ruby-on-rails heroku redis

Try this:

heroku config --long | grep REDIS

to see what your REDISTOGO_URL is. You might have set it accidentally.
