在安装CentOS 6.x的过程中会出现以下界面：
这些选项有什么区别呢？转载一位网友的描述：
Desktop:基本的桌面系统，包括常用的桌面软件，如文档查看工具
Minimal Desktop:基本的桌面系统，包含的软件更少
Minimal:基本的系统，不包含任何可选的软件包
Basic Server:安装的基本系统的平台支持，不包含桌面
Database Server:基本系统平台，加上MySQL和PostgreSQL数据库的客户端，无桌面
Web Server:基本系统平台，加上PHP,Web server，还有MySQL和PostgreSQL数据库的客户端，无桌面
Virtual Host:基本系统加虚拟化平台
Software Development Workstation:包含的软件包较多，基本系统，虚拟化平台桌面环境，开发工具
这样描述似乎并不准确，笔者希望更详细地了解每个选项所包含的内容，以及它们之间的涵盖关系，以判断自己最终需要选择哪一项。
为此，我在CentOS官网上找到了答案（戳我）：
