#### 反向代理 gRPC 端口(支持 Cloudflare CDN)
|
||
使用 Nginx 或者 Caddy 反向代理 gRPC
|
||
|
||
- Nginx 配置
|
||
|
||
```nginx
|
||
server {
|
||
listen 443 ssl http2;
|
||
listen [::]:443 ssl http2;
|
||
server_name data.example.com; # 你的 Agent 连接 Dashboard 的域名
|
||
|
||
ssl_certificate /data/letsencrypt/fullchain.pem; # 你的域名证书路径
|
||
ssl_certificate_key /data/letsencrypt/key.pem; # 你的域名私钥路径
|
||
ssl_stapling on;
|
||
ssl_session_timeout 1d;
|
||
ssl_session_cache shared:SSL:10m; # 此项可能会和其他配置文件冲突,如冲突请注释此项
|
||
ssl_protocols TLSv1.1 TLSv1.2 TLSv1.3;
|
||
|
||
underscores_in_headers on;
|
||
|
||
keepalive_time 24h;
|
||
keepalive_requests 100000;
|
||
keepalive_timeout 120s;
|
||
|
||
location / {
|
||
grpc_read_timeout 300s;
|
||
grpc_send_timeout 300s;
|
||
grpc_socket_keepalive on;
|
||
grpc_pass grpc://grpcservers;
|
||
}
|
||
}
|
||
|
||
upstream grpcservers {
|
||
server localhost:5555;
|
||
keepalive 512;
|
||
}
|
||
```
|
||
|
||
- Caddy 配置
|
||
|
||
```
|
||
data.example.com:443 { # 你的 Agent 连接 Dashboard 的域名
|
||
reverse_proxy {
|
||
to localhost:5555
|
||
transport http {
|
||
versions h2c 2
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
Dashboard 面板端配置
|
||
|
||
- 首先登录面板进入管理后台 打开设置页面,在 `未接入CDN的面板服务器域名/IP` 中填入上一步在 Nginx 或 Caddy 中配置的域名 比如 `data.example.com` ,并保存。
|
||
- 然后在面板服务器中,打开 /opt/nezha/dashboard/data/config.yaml 文件,将 `proxygrpcport` 修改为 Nginx 或 Caddy 监听的端口,比如上一步设置的 `443` ;因为我们在 Nginx 或 Caddy 中开启了 SSL/TLS,所以需要将 `tls` 设置为 `true` ;修改完成后重启面板。
|
||
|
||
Agent 端配置
|
||
|
||
- 登录面板管理后台,复制一键安装命令,在对应的服务器上面执行一键安装命令重新安装 agent 端即可。
|
||
|
||
开启 Cloudflare CDN(可选)
|
||
|
||
根据 Cloudflare gRPC 的要求:gRPC 服务必须侦听 443 端口 且必须支持 TLS 和 HTTP/2。
|
||
所以如果需要开启 CDN,必须在配置 Nginx 或者 Caddy 反向代理 gRPC 时使用 443 端口,并配置证书(Caddy 会自动申请并配置证书)。
|
||
|
||
- 登录 Cloudflare,选择使用的域名。打开 `网络` 选项将 `gRPC` 开关打开,打开 `DNS` 选项,找到 Nginx 或 Caddy 反代 gRPC 配置的域名的解析记录,打开橙色云启用 CDN。
|
||
|
||
开启`gRPC`后,可能不能立即可用,需要等待一段时间。具体可通过`curl`和使用`nezha-agent -d`来验证:
|
||
|
||
```bash
|
||
localhost:~/agent# curl -H "content-type: application/grpc+proto" -H "authorization: Bearer test" https://xxx.xxx.ovh -v
|
||
* processing: https://xxx.xxx.ovh
|
||

|
||
* Connected to xxx.xxx.ovh (2606:4700:3035::ac43:8bed) port 443
