在nginx中添加藍色配置：

server {
        listen       80;
        server_name  test.jxt.com;
        charset utf-8;
        access_log  logs/jxt.access.log  main;
        location / {
            #root   html;
            #index  index.html index.htm;
            proxy_pass http:
 
//jxt;
            proxy_set_header Host      $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection  "upgrade";
        }
        #error_page  
 
404              /404.html;
        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
