在http中添加 upstream a.com {
server  192.168.5.126:81;从ip
server  192.168.5.27:81;
}
进入 vim /etc/nginx/conf.d/default.conf
server {
listen       81;
server_name  a.com; //主域名

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

location / {
proxy_pass         http://a.com; proxy_set_header   Host             $host;
proxy_set_header   X-Real-IP        $remote_addr;
proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
#       root   /usr/share/nginx/html;
#       index  index.html index.htm;
