nginx代理本地图片、视频及音频文件

在映射目录放相关文件，并在nginx中添加server即可

server {
        listen       192.168.x.a:9001;
        server_name  192.168.x.b;
        charset utf-8;
       location ~ .*\.(gif|jpg|jpeg|png)$ {
            expires 24h;
            root /opt/nginx/resources/;#指定存放路径
            proxy_store on;
            proxy_store_access user:rw group:rw all:rw;
            proxy_temp_path         /opt/nginx/resources/;#图片访问路径

            }
        }
