其实购入这个小鸡纯纯吃灰，网络慢成渣，做科学上网的话YTB最多能跑到5000Kbps左右，勉强看1080P分辨率的视频没问题，只能拿做探针用。但不知为啥安装哪吒探针后过段时间自动离线了。登录ssh发现机器并没有重启，考虑可能是进程被杀了，通过脚本重启因为alpine无systemctl，所以重启Agent会失败。通过搜寻网络解决了此问题，记录一下，以防以后用到。

修改 SERVER、SECRET、TLS 然后在 shell 中执行

增加运行权限

chmod +x /etc/init.d/nezha-agent

运行 Nezha-Agent

rc-service nezha-agent start

添加开机自启动

rc-update add nezha-agent

以上内容参考自Nezha Wiki

在 其他 Linux 如 Alpine 使用 Openrc 的发行版 安装 Agent
