# 树莓派

Fluent Bit 发布的软件包为 **td-agent-bit**，可用于 Raspberry，特别是 [Raspbian](http://raspbian.org) 的发行版，支持以下版本:

* Raspbian Buster (10)
* Raspbian Stretch (9)
* Raspbian Jessie (8)

## Server GPG key

第一步，将我们的服务器 GPG 密钥添加到您的密钥环中，这样就可以获取我们签名的软件包:

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

## Update your sources lists

在 Debian 及其衍生系统，例如 Raspbian 上，您需要将我们的 APT 服务器实例添加到您的源列表中，请在 **/etc/apt/sources.list** 文件中添加如下内容:

#### Raspbian 10 (Buster)

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

#### Raspbian 9 (Stretch)

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

#### Raspbian 8 (Jessie)

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

### Update your repositories database

现在，让您的系统更新 *apt* 数据库:

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

## Install TD Agent Bit

现在，使用以下 *`apt-get`* 命令，您可以安装最新的 *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
```

如果进行状态检查，应该会看到类似如下的输出:

```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
...
```

**td-agent-bit** 的默认配置是收集 CPU 使用率的指标数据并将记录发送到标准输出，您可以在 *`/var/log/syslog`* 文件中看到输出的数据。
