带有子域名和两台服务器的 nginx

我有两台服务器：第一台服务器的 IP 地址为 192.168.1.216，主机名为hub.domain.tld (jupyterhub)。DNS 记录指向公网 IP 地址，所有对端口80和 的请求都443转发到192.168.1.216。

第一台服务器上的初始 Nginx 配置设置很简单，并且运行正常。

但是，问题出现在第二台服务器上，该服务器也配置了 Nginx，如下所述。问题是，所有发送到的请求vscode.domain.tld都被重定向到，hub.domain.tld而不是192.168.1.234:8080(code-server)

但是，当我移动并将此配置添加到第一台服务器时，一切都运行正常。

我想拆分配置文件。因为我想在docker compose中容器化Nginx：

  • 代码服务器，
  • 探索数据库，
  • grafana。

Nginx 未正确配置proxy_pass，没有代理配置将流量引导code-server至192.168.1.234:8080。

在您的 HTTPS 服务器块中，将此块添加到代理请求中：

server {
    listen 443 ssl;
    server_name vscode.domain.tld;

    ssl_certificate /etc/letsencrypt/live/vscode.domain.tld/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/vscode.domain.tld/privkey.pem;

    # ...

    location / {
        proxy_pass http://192.168.1.234:8080;
        proxy_set_header Host $host;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Accept-Encoding gzip;
    }
}
