下面详细的介绍前面第三种方式的搭建：

一：先上图，

前端界面

二：跳转页面

三：功能介绍

网上有很多使用Nginx搭建文件服务器的教程，我都看了，只能实现基本的功能，因为Nginx本身就支持文件的上传，但是没有完成文件的改名和文件位置存储，我使用Lua实现了。本来还使用了MySQL做了登录验证，但是使用lua写的很尴尬，我写到了FastDFS(第四种搭建文件系统的方式)。FastDFS也是用Nginx实现，严格来说是分布式文件系统，CDN相关。

提供了两种文件上传的方式，一种是上传到大仓库，一种是重命名到小文件夹。Nginx提供了文件上传下载的功能，还是temp file，你需要使用Lua语言进行重新定义。FastDFS是将每个文件的相关信息，持久化到数据库，方便查询。

安装Nginx，安装Lua环境，编译啥的，服务器部署，自己去折腾吧，我都不好意思写。。。。。。

四：上代码

页面代码：

        }

        .clearfix:after {
            clear: both;
        }

        .clearfix {

}

具体的文件处理部分：content_by_lua_file "/usr/local/openresty/nginx/conf/mylua/onupload.lua"; 附件上传

做到这步骤，你的文件已经可以正常上传，下载了，但是在临时路径，文件名是000000index这种格式，很怪。
