在AWS上部署NodeJS Websocket服务器-Elastic Beanstalk

Question

我正在设置aws elasticbeanstalk服务器，并希望支持TCP连接。

我完成的步骤：

• 在端口：3050上运行的Websocket服务器
• 弹性豆茎
• Elastic Beanstalk AWS Classic负载均衡器
• 套接字服务器的Nginx代理配置

我的Websocket服务器

• 套接字端口为3050

const socketHandler = require('./util/handler');
const logger = require('./util/Logger')
const { createServer } = require('http');

const express = require('express');
const WebSocket = require('ws');

const app = express();

const server = createServer(app);
const ws = new WebSocket.Server({ server });


ws.on('connection', (socket,req) => {
  socket.send('Hello')
  console.log('CLIENT CONNECTED');
  logger.info({title: "User Connected", message : `IP ${req.connection.remoteAddress}`, line : "50", file:"util/handler.js"})
  socket.on('message', (data) => socketHandler.dataResolver(socket,data));
  socket.on('error', (err) => socketHandler.errorHandler(err));
  socket.on('close', () => socketHandler.leaveHub(socket))
});

ws.on('error' , (err) => {
  console.log(err)
})



server.listen(3050, function() {
  console.log('Listening on http://localhost:3050');
});

NGINX配置

files:
  /etc/nginx/conf.d/proxy.conf:
    mode: "000644"
    owner: root
    group: root
    content: |
      upstream nodejs {
        server 127.0.0.1:3050;
        keepalive 256;
      }

      server {
        listen 8080;

        if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})T(\d{2})") {
            set $year $1;
            set $month $2;
            set $day $3;
            set $hour $4;
        }
        access_log /var/log/nginx/healthd/application.log.$year-$month-$day-$hour healthd;
        access_log  /var/log/nginx/access.log  main;

        location / {
            proxy_pass  http://nodejs;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
            proxy_http_version 1.1;
            proxy_set_header        Host            $host;
            proxy_set_header        X-Real-IP       $remote_addr;
            proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
        }

        gzip on;
        gzip_comp_level 4;
        gzip_types text/html text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

        location /static {
            alias /var/app/current/static;
        }

      }

container_commands:
 removeconfig:
    command: "rm -f /tmp/deployment/config/#etc#nginx#conf.d#00_elastic_beanstalk_proxy.conf /etc/nginx/conf.d/00_elastic_beanstalk_proxy.conf"

AWS-Elastic Beanstalk Classic负载均衡器设置

客户端设置

const WebSocket = require('ws');

const ws = new WebSocket('ws://elasticbeanstalk_url');

ws.onopen = function () {
    console.log('CONNECTED')
};
ws.onmessage = function({data}) {
    console.log(data)
}

ws.onerror = function (err) {
    console.log(err.error)
}

我遇到错误：套接字挂起

Error: socket hang up
    at connResetException (internal/errors.js:559:14)
    at Socket.socketOnEnd (_http_client.js:433:23)
    at Socket.emit (events.js:208:15)
    at endReadableNT (_stream_readable.js:1168:12)
    at processTicksAndRejections (internal/process/task_queues.js:77:11) {
  code: 'ECONNRESET'
}

我正在寻找将近15个小时的解决方案。
