Setting up Redis on Rails (localhost)

In config/initializers/redis.rb, you will see how Redis is instantiated. The Redis instance will be stored in a global variable $redis and you may call this variable anywhere in the Rails app. For local host development, make sure to use

$redis = Redis.new(:host => 'localhost', :port => 6379)

and comment out the other line because that one is for deployment to Heroku

Redis instance on Heroku

Redis URL can be found by running

$ heroku config | grep REDIS

Redis instance info can be found by running

$ heroku redis:info

Start running

First you need to start your Redis server by typing in
