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。
