1.在nginx/conf/nginx.conf中添加：
include conf.d/*.conf;
2.在同级目录下新建conf.d文件夹，在conf.d文件夹中新建自定义配置文件，如：cms.conf

upstream cms_server {
       server localhost:8080;
}
server
{
   listen 80;
   server_name www.aa.com;
   location / {
       proxy_redirect off;
       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_pass http://cms_server;
   }
}
server
{
   listen 80;
   server_name www.bb.com;
   location / {
       proxy_redirect off;
       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_pass http://cms_server;
   }
}
server
{
   listen 80;
   server_name www.cc.com;
   location / {
       proxy_redirect off;
       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_pass http://cms_server;
   }
}
server
{
   listen 80;
   server_name www.dd.com;
   location / {
       proxy_redirect off;
       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_pass http://cms_server;
   }
}
