Question

我正在尝试在我的本地计算机上实现棘轮套接字Hello word，但是当我使用

运行服务器服务时，所有内容都能完美运行但是在vps centos服务器上

ssh Command : php chat-server.php

它开始正确地侦听端口（我可以在linux上看到该端口正在侦听），但是当我打开＆＃34; clint.html＆＃34;页面方法onopen永远不会触发，但服务器说

新客户连接！

并且在2分钟之后它说

客户端已断开连接

如果我向客户发送消息，则需要2分钟，然后客户端才会收到消息，但会再次断开连接在我看来，服务器和客户端之间没有稳定的连接。每当我检查websocket.readyState时它不等于1
我禁用了防火墙和vps服务器上的任何安全性，但仍然有这个问题。我必须提到正常的php套接字函数没有问题，因为我可以测试它并every thing works 但关于棘轮似乎它挂在onopen方法上。

端口9091已打开
防火墙已停用

但棘轮连接有问题

chat-server.php：

use Ratchet\Server\IoServer;
use Ratchet\Http\HttpServer;
use Ratchet\WebSocket\WsServer;
use MyApp\Chat;
require dirname(__DIR__) . '/vendor/autoload.php';

$server = IoServer::factory(
    new HttpServer(
        new WsServer(
            new Chat()
        )
    ),
    9091
);
echo date("Y-m-d H:i:s")." chat-server Started on port 9091 \n";
$server->run();

Chat.php类：

namespace MyApp;
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;
class Chat implements MessageComponentInterface {
protected $clients;

public function __construct() {
    $this->clients = new \SplObjectStorage;      
}

public function onOpen(ConnectionInterface $conn) {        
    $this->clients->attach($conn);
    echo date("Y-m-d H:i:s")." New connection! ({$conn->resourceId})\n";        
    $conn->send("Hello {$conn->resourceId} from server at : ".date("Y-m-d H:i:s"));
    echo date("Y-m-d H:i:s")." Hello Sent to  ({$conn->resourceId})\n"; 

}

public function onMessage(ConnectionInterface $from, $msg) {
    $numRecv = count($this->clients) - 1;
    echo sprintf(date("Y-m-d H:i:s").'Connection %d sending message "%s" to %d other connection%s' . "\n"
        , $from->resourceId, $msg, $numRecv, $numRecv == 1 ? '' : 's');
    foreach ($this->clients as $client) {
        if ($from !== $client) {                
            $client->send($msg);
        }
    }
}

public function onClose(ConnectionInterface $conn) {        
    $this->clients->detach($conn);
    echo date("Y-m-d H:i:s")." Connection {$conn->resourceId} has disconnected\n";
}

public function onError(ConnectionInterface $conn, \Exception $e) {
    echo date("Y-m-d H:i:s")." An error has occurred: {$e->getMessage()}\n";
    $conn->close();
}
}

客户端html：

$(document).ready(function(){  
   connect();  
});

var wsUri = "ws://myserverdomain.comOrIP:9091";   


 function connect() {
  var ws = new WebSocket(wsUri);

  ws.onopen = function() {
    var now = new Date();
    console.log(now + ' Connected to '+wsUri);        
  };

  ws.onmessage = function(e) {
      var now = new Date();
    console.log(now + ' Message Recived From Server :', e.data);
  };

  ws.onclose = function(e) {
      var now = new Date();
    console.log(now +' Socket is closed. Reconnect will be attempted in 1 second.', e.reason);
    setTimeout(function() {
      connect();
    }, 1000)
  };

  ws.onerror = function(err) {
      var now = new Date();
    console.error(now + ' Socket encountered error: ', err.message, 'Closing socket')
    console.error(err)
    ws.close()
  };
}

Ratchet onopen客户端没有开火
