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，还要本身选择语言，时区，等等交互界面，为了避免进行交互界面。 因此才有了 centos6.6 Kickstart无人值守安装（三）：配置篇 B kickstart上场。

咱们这里用到的是kickstart的配置文本——ks.cfg，手写的，更自由，可是也难，细节不少。kickstart也有界面版的，经过界面配置ks.cfg ，最终仍是生成一个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： 完彻底全写一个ks.cfg文件很麻烦，易出错。其实在咱们安装好一个完整的linux操做系统后，系统会自动生成一个ks.cfg文件，该文件位于/root/anaconda-ks.cfg 咱们能够将其复制到咱们须要的地方，顺便贴一下个人ks.cfg cp /root/anaconda-ks.cfg /mnt/install/ks.cfg chmod 777 /mnt/install/ks.cfg [root@localhost ~]# cat /mnt/install/ks.cfg # Kickstart file automatically generated by anaconda.

好了 ，如今是全自动安装了。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。
