For the last 8 years I have worked on 40+ Ruby projects and Redis was an integral part of all of them. Redis remains my favorite to cache values and holds on to things temporarily (with a TTL). This tutorial describes how you install and use Redis in your Mac (iMac, MacBook, MacMini) running macOS.

Note: I would be assuming you have Homebrew installed already. If not, you should. It makes installing libraries in macOS so much easier.

Procedure

Step 1: Update brew and install

brew update
brew install redis

This will give access to redis-server and redis-cli. But by default the service won't be running.

Step 2: Start the redis service

brew services start redis

Step 3: You can now use redis as you wish

jdeen@iMac:~/Desktop|⇒  redis-cli
127.0.0.1:6379>

Extra

You can check if Redis is running using:

jdeen@iMac:~/Desktop|⇒  redis-cli ping
PONG

Like you started the service, you can stop it:

brew services redis stop
