Question

我想在两个盒子上部署我的节点websocket服务，并使用haproxy对其进行屏蔽，但它不起作用。

frontend http-in
  mode http
  bind *:80

  acl is_websocket path_beg /prodSocket                                                                     
  acl is_websocket hdr(Upgrade) -i WebSocket
  acl is_websocket hdr_beg(Host) -i ws
  use_backend prodSocket if is_websocket

  acl is_websocket path_beg /demoSocket                                                                     
  acl is_websocket hdr(Upgrade) -i WebSocket
  acl is_websocket hdr_beg(Host) -i ws
  use_backend demoSocket if is_websocket

backend demoSocket
  timeout server 180s
  server 148.251.76.84 148.251.76.84:9000 weight 1 maxconn 1024 check


backend prodSocket
  timeout server 180s
  server 148.251.76.85 148.251.76.85:9000 weight 1 maxconn 1024 check

客户代码 -

 var socket = io('http://localhost/prodSocket', {                                                            
      'force new connection': false,
      'reconnection delay': 500,
      'max reconnection attempts': 10,
 });
 socket.emit('client', { my: 'data' });
 socket.on('news', function (data) {
     console.log(data);
});

上述代码不起作用，但如果我进行了以下更改，则可以正常工作 -

frontend http-in
  mode http
  bind *:80

  acl is_websocket path_beg /socket.io                                                                     
  acl is_websocket hdr(Upgrade) -i WebSocket
  acl is_websocket hdr_beg(Host) -i ws
  use_backend socket if is_websocket

backend socket
  timeout server 180s
  server 148.251.76.84 148.251.76.84:9000 weight 1 maxconn 1024 check

客户代码 -

 var socket = io('http://localhost:9090', {                                                            
      'force new connection': false,
      'reconnection delay': 500,
      'max reconnection attempts': 10,
 });
 socket.emit('client', { my: 'data' });
 socket.on('news', function (data) {
     console.log(data);
});

我知道socket io正在调用/socket.io端点来创建套接字连接但是如何在两个不同的端点上部署我的服务呢？

版本 -

Socket.io - 1.4.5
节点 - v5.6.0
HAproxy - 1.4.24
Ubuntu - 14.04

使用/socket.io端点的HAProxy日志 -

config -

frontend http-in
  mode http
  bind *:9090

  acl is_websocket path_beg /socket.io
  acl is_websocket hdr(Upgrade) -i WebSocket                                                               
  acl is_websocket hdr_beg(Host) -i ws
  use_backend socket if is_websocket

CLient脚本 -

 var socket = io('http://localhost:9090', {                                                 
      'force new connection': false,
      'reconnection delay': 500,
      'max reconnection attempts': 10,
 });

具有多个端点的HA代理上的节点Socket.io
