node socket.io multiple room chat demo
在http下新增upstream配置ip_hash，如果多机，则添加多个替换下面ip地址即可。然后配置server里的location规则。nginx须>1.3才可支持websocket。
upstream io_nodes {
ip_hash;
server 127.0.0.1:6001;
server 127.0.0.1:6002;
server 127.0.0.1:6003;
server 127.0.0.1:6004;
server 127.0.0.1:6005;
server 127.0.0.1:6006;
server 127.0.0.1:6007;
server 127.0.0.1:6008;
}
server {
listen 3000;
server_name io.yourhost.com;
location / {
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_http_version 1.1;
proxy_pass http://io_nodes;
}
}

以上命令启动master进程并监听6001-600n端口，根据cpu核数而定。
输入参数，并建立websocket连接。
