下载 agent
x86架构，应下载 nezha-agent_linux_amd64.zip
arm架构，应下载 nezha-agent_linux_arm64.zip
从 https://github.com/nezhahq/agent/releases 下载 nezha-agent 并上传到国内服务器，使用 unzip 解压，将二进制文件放到 /opt/nezha/agent。
这里可以使用反代加速 github，在国内机上直接下载，参考步骤如下（请自行确认反代地址、agent 版本号和平台）
mkdir /opt/nezha/agent -p
cd /opt/nezha/agent
wget https://github.com/nezhahq/agent/releases/download/v0.15.19/nezha-agent_linux_amd64.zip
unzip nezha-agent_linux_amd64.zip
chmod +x nezha-agent配置 systemd
vim /etc/systemd/system/nezha-agent.service创建 /etc/systemd/system/nezha-agent.service 文件，填入以下代码
自行修改代码中的 -s IP地址/域名:5555 -p 密钥部分
注意：如果国内机只有 IPv6 可访问到面板服务器，必须为面板服务器的域名添加 AAAA IPv6 记录（面板服务器可套 WARP 获取 IPv6）
