背景：   IM 即时通讯时候  ， 前期我用的是IP 没什么问题，当然上线肯定要搞个域名搞搞了！  

　　　那么问题来了------》Nginx  我按照原先那样配置时候不行了，

 

 

连接不了。

 

解决方法：

重要位置需要配置的

    map $http_upgrade $connection_upgrade {

        default upgrade; '' close; }

 

proxy_http_version 1.1;

proxy_set_header Upgrade $http_upgrade;

proxy_set_header Connection "upgrade";

 

 

完美解决问题了！  什么东西都要自己去动手 ，你才能发现问题解决问题！  每天用嘴说反向代理  ，负载均衡！  然后都他妈的空谈！
