Redis Installation

Install Redis

Redis is an in-memory key-value store which NetBox employs for caching and queuing. This section entails the installation and configuration of a local Redis instance. If you already have a Redis service in place, skip to the next section.

sudo apt install -y redis-server

Before continuing, verify that your installed version of Redis is at least v4.0:

redis-server -v

You may wish to modify the Redis configuration at /etc/redis.conf or /etc/redis/redis.conf, however in most cases the default configuration is sufficient.

Verify Service Status

Use the redis-cli utility to ensure the Redis service is functional:

redis-cli ping

If successful, you should receive a PONG response from the server.
