# Debian

Fluent Bit is distributed as **td-agent-bit** package and is available for the latest (and old) stable Debian systems: Buster, Stretch and Jessie. 

## Server GPG key

The first step is to add our server GPG key to your keyring, on that way you can get our signed packages:

```
$ wget -qO - https://packages.fluentbit.io/fluentbit.key | sudo apt-key add -
```

## Update your sources lists

On Debian, you need to add our APT server entry to your sources lists, please add the following content at bottom of your **/etc/apt/sources.list** file:

#### Debian 10 (Buster)

```
deb https://packages.fluentbit.io/debian/buster buster main
```

#### Debian 9 (Stretch)

```
deb https://packages.fluentbit.io/debian/stretch stretch main
```

#### Debian 8 (Jessie)

```
deb https://packages.fluentbit.io/debian/jessie jessie main
```

### Update your repositories database

Now let your system update the *apt* database:

```bash
$ sudo apt-get update
```

## Install TD Agent Bit

Using the following *apt-get* command you are able now to install the latest *td-agent-bit*:

```
$ sudo apt-get install td-agent-bit
```

Now the following step is to instruct *systemd* to enable the service:

```bash
$ sudo service td-agent-bit start
```

If you do a status check, you should see a similar output like this:

```bash
sudo service td-agent-bit status
● td-agent-bit.service - TD Agent Bit
   Loaded: loaded (/lib/systemd/system/td-agent-bit.service; disabled; vendor preset: enabled)

           └─6739 /opt/td-agent-bit/bin/td-agent-bit -c /etc/td-agent-bit/td-agent-bit.conf
...
```

The default configuration of **td-agent-bit** is collecting metrics of CPU usage and sending the records to the standard output, you can see the outgoing data in your */var/log/syslog* file.
