# Redis installation Netbox

[Redis](https://redis.io/) 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](https://netbox.readthedocs.io/en/stable/installation/3-netbox/).

```
sudo apt install -y redis-server 
```

<div class="tabbed-control tabbed-control--prev" hidden="" id="bkmrk-">  
</div><div class="tabbed-control tabbed-control--next" hidden="" id="bkmrk--1">  
</div>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.
