当我们登录Download CentOS 7下载界面的时候，会看到DVD ISO，Everything ISO，Minimal ISO三个版本，不知道怎么下载centos 7 iso镜像，下面就来简单介绍一下这三个版本的区别。
Centos DVD ISO版本是标准安装版，有windows桌面图形化界面，适合于新手学习使用。
Centos Everything ISO版本是对标准版进行了补充，集成了所有的安装软件。
Minimal ISO版本则是server linux服务器版，没有图形化界面显示，全部是命令行。
centos 7 iso镜像尽量用国内的，因为下载比较快，例如163 mirror和aliyun mirror这些镜像是非常不错的，下面是下载地址，以Minimal iso为例。
