## 下载 Agent
1. 先去哪吒的下载页下载符合自己群晖 CPU 架构的 Agent 客户端。我是 DS420+Intel CPU下载 nezha-agent_linux_amd64.zip。
<https://github.com/nezhahq/agent/releases>
2. 解压后,把里面的二进制文件随便放到一个地方

3. SSH 到群晖,使用 `sudo -i` 切换到 root 账号
4. 找到刚才放进去的文件,共享文件夹一般在 /volume1 下面。刚才我是放在了 AppData 这个共享文件夹里,那二进制文件就在 /volume1/AppData 下

## 测试启动
首先要手动执行下二进制文件,确认使用正常。
1. 在 Dashboard 里创建一个新设备,获取链接密码
2. 进到 agent 所在文件夹后,通过执行 ./nezha-agent 可以查看使用帮助

3. 基本上指定一下服务器地址和密码即可,命令为
```bash
./nezha-agent -s <Dashboard服务器地址>:<端口> -p <连接密码>
```
4. 执行后,没报错,并且在 Web 上能看到信息就可以

5. 记下自己的执行命令,并把 `./` 替换成绝对路径,比如我的文件放在 `/volume1/AppData` 下,那我的执行命令就是
```bash
/volume1/AppData/nezha-agent -s <Dashboard服务器地址>:<端口> -p <连接密码>
```
## 配置服务
直接执行命令虽然能用,但是一关窗口就停止运行了。丢到 screen 里也不行,因为 Agent 会自动更新更新时会停止进程。DSM 7 内置 systemctl 命令,可以很方便设置为系统服务,保活进程。
1.`/usr/lib/systemd/system` 下创建一个 `nezha-agent.service` 文本文件
```bash
vim /usr/lib/systemd/system/nezha-agent.service
```
内容如下
```bash
[Unit]
Description=Nezha Agent
After=syslog.target
[Service]
Type=simple
User=root
Group=root
ExecStart=<刚才记下的执行命令>
Restart=always
[Install]
WantedBy=multi-user.target
```
2. 加载配置文件
```bash
systemctl daemon-reload
```
3. 启动服务
```bash
systemctl enable nezha-agent
systemctl start nezha-agent
```
4. 查看状态
```bash
systemctl status nezha-agent
```
