node.js - 在同一端口上使用 Node.js Express 和 TCP 服务器配置 NGINX？

Question

我正在尝试设置我的 Node 服务器，它使用 express 在端口 3000 上为文件提供服务，并使用 net 库在端口 5052 上为 TCP 服务器提供服务，因此:

const express = require('express');
const app = express();
const httpServer = require('http').Server(app);
const io = require('socket.io').listen(httpServer);
const path = require('path');
const net = require('net');

app.get('/', (req, res) => {
  res.sendFile(path.join(__dirname, './public/index.html'))
});

let server = net.createServer(function(socket) {
 // Left out for brevity
}

server.listen(5052, 'localhost');

httpServer.listen(3000, () => {
  console.log('Ready on port 3000');
});

在本地，这一切都运作良好。我可以加载 localhost:3000 并获得我的 HTML 服务并且它连接到 socket.io 正常。我也可以完美地连接到端口 5052 上的服务器，一切都很好。我只是无法让 nginx 正确地提供所有服务。这是我拥有的:

server {
    listen 80 default_server;
    listen [::]:80 default_server;

    server_name mycoolproject.com www.mycoolproject.com;

    location / {
        proxy_pass http://localhost:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }

  listen 443 ssl;
  ssl_certificate /etc/letsencrypt/live/mycoolproject.com/fullchain.pem;
  ssl_certificate_key /etc/letsencrypt/live/mycoolproject.com/privkey.pem;
  include /etc/letsencrypt/options-ssl-nginx.conf;

  ssl_dhparam /etc/ssl/certs/dhparam.pem;

  if ($scheme != "https") {
      return 301 https://$host$request_uri;
  }

}

server {
    listen 5053;

    server_name mycoolproject.com www.mycoolproject.com;

    location /{
        proxy_pass http://localhost:5052;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection 'upgrade';
                proxy_set_header Host $host;
                proxy_cache_bypass $http_upgrade;
    }
}

当我导航到 mycoolproject.com 时，网站加载正常，因此 express 端工作正常。我只是无法连接到 5053 上的服务器。有什么想法吗？

您需要为 Nginx 配置不同的端口，5052 被 Node.js 占用。

server {
    listen 5053;

    server_name mycoolproject.com www.mycoolproject.com;

    location /{
        proxy_pass http://localhost:5052;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection 'upgrade';
                proxy_set_header Host $host;
                proxy_cache_bypass $http_upgrade;
    }
}

然后你可以连接到mycoolproject.com:5053
