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.

!!! note NetBox v2.9.0 and later require Redis v4.0 or higher. If your distribution does not offer a recent enough release, you will need to build Redis from source. Please see the Redis installation documentation for further details.

=== "Ubuntu"

```no-highlight
sudo apt install -y redis-server
```

=== "CentOS"

```no-highlight
sudo yum install -y redis
sudo systemctl start redis
sudo systemctl enable redis
```

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
