Nginx缓存和程序动静分离设置
参考：http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_cache_path语法
proxy_cache_path path keys_zone=name:size ;
配置格式：
proxy_cache_path /data/nginx/cache levels=1:2 keys_zone=one:10m;
#定义/data/nginx/cache为缓存目录；levels=1:2 有2级子目录，最多为3级子目录，用冒号隔开定义3个数字，每个数字表示其目录名称;keys_zone=one:10m 用多大的空间保存键值；
