当公司只存在一个公网地址时候，需要影射多个域名，并且域名下面要配置二级目录的时候

可以参照如下配置

upstream h5_game {      server  10.0.100.153:80;}server{    listen 3116;     server_name  www.xxx.com;    location / {        proxy_pass         http://h5_game;          proxy_set_header   Host             $host;        proxy_set_header   X-Real-IP        $remote_addr;        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;    }location /big/ {        proxy_pass http://10.0.100.153:80/big/;}location /small/ {         proxy_pass http://10.0.100.153:80/small/;}}

　 访问地址：www.xxx.com/big   www.xxx.com/small，可以直接访问后端服务器的耳机域名
