#####CGI#####
CGI
通用网关接口(CGI)是网站上放置动态内容的最简单的方法。CGI脚本可用于许多目
的,但是谨慎控制使用哪个CGI脚本以及允许谁添加和运行这些脚本十分重要。编写质量差的CGI
脚本可能为外部攻击者提供了破坏网站及其内容安全性的途径。因此,在Web服务器级别和
SELinux策略级别,都存在用于限制CGI脚本使用的设置。

1. 上传 upload 目录中的文件到服务器
2. 设置目录属性（windows 服务器可忽略这一步）
以下这些目录需要可读写权限
./config
./data 含子目录
3. 执行安装脚本 /install/
请在浏览器中运行 install 程序，即访问 http://您的域名/论坛目录/install/
4. 参照页面提示，进行安装，直至安装完毕
