centos6.6 Kickstart無人值守安裝（三）：配置篇 B

centos6.6 Kickstart無人值守安裝（二）：配置篇 A 中，試驗成功的你會發現：只不過是自動的到達了安裝界面的，還要本身選擇語言，時區，等等交互界面，爲了避免進行交互界面。 因此纔有了 centos6.6 Kickstart無人值守安裝（三）：配置篇 B kickstart上場。

咱們這裏用到的是kickstart的配置文本——ks.cfg，手寫的，更自由，可是也難，細節不少。kickstart也有界面版的，經過界面配置ks.cfg ，最終仍是生成一個ks.cfg文件，只不過界面簡單。 ##界面配置方式： 可參照 這篇文章 ##文字配置方式： 完徹底全寫一個ks.cfg文件很麻煩，易出錯。其實在咱們安裝好一個完整的linux操做系統後，系統會自動生成一個ks.cfg文件，該文件位於/root/anaconda-ks.cfg 咱們能夠將其複製到咱們須要的地方，順便貼一下個人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 ，如今是全自動安裝了。不會彈出界面了。不截圖了。 中途可能會遇到麻煩，細心，先看清報錯信息，嘗試看懂更改，實在不懂去google。
