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.
!!! warning "Redis v4.0 or later required" 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
```
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.
