Nginx配置WebSocket

在使用了Nginx做负载均衡之后，那么原先的WebSocket将没法连接到服务器（废话！），那么我们需要配置Nginx，将WebSocket请求也进行反向代理。

nginx.conf配置：

#websocket配置
map $http_upgrade $connection_upgrade {
            default upgrade;
            '' close;
}

server {
    listen       801;
    server_name  localhost;
    #布置websocket处理服务器
    location / {
            proxy_pass http://127.0.0.1:8110;

            #配置Nginx支持webSocket开始
            proxy_set_header Host $http_host;

            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
    }
}

server {  
    listen 4431;  
    server_name localhost;  
    ssl on;  
    root html;  
    ssl_certificate   cert/XXXXXXXXX.pem;  
    ssl_certificate_key  cert/XXXXXXXXX.key;  
    ssl_session_timeout 5m;  
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;  
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2 SSLv2 SSLv3;  
    ssl_prefer_server_ciphers on;  
    #布置websocket处理服务器  
    location / {
                proxy_pass http://127.0.0.1:8110;  

                #配置Nginx支持webSocket开始  
                proxy_set_header Host $http_host;  

                proxy_http_version 1.1;  
                proxy_set_header Upgrade $http_upgrade;  
                proxy_set_header Connection "upgrade";  
    }  
}  

客户端连接时，就使用ws和wss协议分别连接以上的801和4431端口。
