Update redis cache setting on ruby on rails project

Question

I am trying to locate to set the Redis cache setting on the Ruby on Rails project, but I am not able to find the path to set it up.

As I was looking on /etc/redis/redis.conf but I don't see anything related to Ruby on rails to update.

Is there a path for ruby on rails where I need to update the local or external Redis cache endpoint need to be updated?

Are you trying to tell your Rails application where Redis is located on your computer so that the Rails application can use it ? — Maxence

Yes, I'm looking for the same setting where do I define the Redis settings on Rails? — Arunkumar

You can create config/redis.yml like this :

development:
  url: redis://localhost:6379/
  db: 0
 
production:
  url: 
  db: 0

test: 
  url: redis://localhost:6379/
  db: 1

And then create an initializer config/initializrs/redis.rb like this

conf = Rails.application.config_for(:redis)
REDIS = Redis.new(conf)

Now in your Rails app, you can use : REDIS.set("today","monday")

REDIS.get("today") will return "monday".

Also you can use Rails.application.config_for(:redis) to make a reference to your Redis config in any other intitializer
