description: Using Redis as a cache or primary data store on your serverlet.
---

Redis is a very fast key-value database that can be used as a cache, or even as a primary data store. It's considered a standard presence on web hosting. See the Redis [documentation](https://redis.io/documentation) for more information.

## First use

By default, Redis is disabled. You can enable it from Administration, on the Software tab (see [Serverlet Control](/docs/serverlet/control/)):

```
$ app enable redis
```

Starting it:

```
$ app start redis
```

## Control

Control it using:

```
$ redis-cli
```

## Configuration

All Redis configuration is stored in the `/srv/config/redis/redis.conf` file. By default, no password is configured and the service listens on TCP port 6379.
