这里使用Google举例，如何使用http_sub_module模块搭建一个镜像站点
Nginx编译参数：
./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-pcre=/root/pcre-8.44 --with-pcre-jit --with-openssl=/root/openssl-1.0.2u --with-http_realip_module --with-http_stub_status_module --with-http_gzip_static_module --with-threads --with-file-aio --with-stream --with-stream_ssl_module --with-http_v2_module --with-http_ssl_module --with-http_sub_module --with-ld-opt=-ljemalloc --add-module=/root/ngx_brotli
Nginx配置文件：
