CEDAR uses Redis to implement a message queue for communication between components of the system.

Install Redis

Please install Redis, version 6.2:

brew install redis@6.2

And pin this version:

brew pin redis@6.2

Do not add Redis as a background service! We will have scripts in place which will start it when necessary.

Start Redis


Check Redis status

cedarcli status

You should see the following line in the output:

| Redis-persistent           | Running | redisPing   | 6379|                   |
