nginx 反向代理nodejs websocket，实现负载均衡

1.要求安装nginx1.3以上版本，具体安装请查询各种文档

2.nginx配置

map $http_upgrade $connection_upgrade {
        default upgrade;
        ''      close;
}

upstream nodesocket {
        server 127.0.0.1:10080 fail_timeout=20s;
        server 127.0.0.1:10081 fail_timeout=20s;
    }  

    server {
        listen 80;
        server_name socket.localhost.com;
        location / {
            proxy_pass http://nodesocket;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection $connection_upgrade;
        }  
    }    

 3.基本上这样就行了

需要注意的点

做的测试页面使用另外一个域名，然后去连socket对应的独立域名就行，别混合用，混合弄比较容易出问题点
