centos6.6 Kickstart无人值守安装（三）：配置篇 B

centos6.6 Kickstart无人值守安装（二）：配置篇 A 中，试验成功的你会发现：只不过是自动的到达了安装界面的，还要自己选择语言，时区，等等交互界面，为了不进行交互界面。
所以才有了 centos6.6 Kickstart无人值守安装（三）：配置篇 B kickstart上场。

我们这里用到的是kickstart的配置文本——ks.cfg，手写的，更自由，但是也难，细节很多。kickstart也有界面版的，通过界面配置ks.cfg ，最终还是生成一个ks.cfg文件，只不过界面简单。

界面配置方式：

可参照 这篇文章

文字配置方式：

完完全全写一个ks.cfg文件很麻烦，易出错。其实在我们安装好一个完整的linux操作系统后，系统会自动生成一个ks.cfg文件，该文件位于/root/anaconda-ks.cfg 我们可以将其复制到我们需要的地方，顺便贴一下我的ks.cfg

好了 ，现在是全自动安装了。不会弹出界面了。不截图了。
中途可能会遇到麻烦，细心，先看清报错信息，尝试看懂更改，实在不懂去google。
