1、在nginx.conf中添加负载均衡的配置   
upstream gulimall{
	# 网关的地址
	server 192.168.56.1:88;
}    
2、在gulimall.conf中添加如下配置
server {
	# 监听以下域名地址的80端口
    listen       80;
    server_name  gulimall.com  *.gulimall.com hjl.mynatapp.cc;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;

    #配置静态资源分离
    location /static/ {
        root   /usr/share/nginx/html;
    }

    #支付异步回调的一个配置
    location /payed/ {
        proxy_set_header Host order.gulimall.com;        #不让请求头丢失
        proxy_pass http://gulimall;
    }

    location / {
        #root   /usr/share/nginx/html;
        #index  index.html index.htm;
        proxy_set_header Host $host;        #不让请求头丢失
        proxy_pass http://gulimall;
    }
