1Panel通过Cloudflare反代哪吒gRPC

前置步骤：
登录Cloudflare，选择使用的域名。打开 网络 选项将 gRPC开关打开。打开橙色云启用 CDN。
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 your_domain.com ，并保存

1.创建一个静态网站，启用HTTPS，配置文件全部替换（注意将 your_domain.com替换为你的信息）：

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;
    server_name domain.com;

    ssl_certificate /www/sites/your_domain.com/ssl/fullchain.pem;
    ssl_certificate_key /www/sites/your_domain.com/ssl/privkey.pem;
    ssl_stapling on;
    ssl_session_timeout 1d;
    ssl_session_cache shared:SSL:10m;
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers 'ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384';
    underscores_in_headers on;

    keepalive_time 24h;
    keepalive_requests 100000;
    keepalive_timeout 120s;

    location / {
        proxy_pass http://127.0.0.1:8008;
        proxy_set_header Host $http_host;
        proxy_set_header Upgrade $http_upgrade;
    }

    location ~ ^/(ws|terminal/.+)$ {
        proxy_pass http://127.0.0.1:8008;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_set_header Host $http_host;
    }

    location ^~ /proto.NezhaService/ {
        grpc_read_timeout 300s;
        grpc_send_timeout 300s;
        grpc_socket_keepalive on;
        grpc_pass grpc://grpcservers;
        access_log off;
    }
}

upstream grpcservers {
    server 127.0.0.1:5555;
    keepalive 512;
}

2.修改 /opt/nezha/dashboard/data/config.yaml里的下面信息：

GRPCHost:domain.com
ProxyGRPCPort: 443
TLS: true

3.关闭通讯端口的外部访问，在 /opt/nezha/dashboard/docker-compose.yaml中修改为：

ports:
  - 127.0.0.1:8008:80
  - 127.0.0.1:5555:5555

4.重启面板
