很多的公司都有需求自動安裝系統下面給大家寫的一些東西希望可以用的到
首先我們需要一個iso鏡像的目錄并在裡面建一個custom的目錄
[[email protected] store_new]# ls -a

EULA_en GPL RELEASE-NOTES-as-IN.html RELEASE-NOTES-it-IT.html RELEASE-NOTES-pt-BR.html ResilientStorage
.discinfo 這個檔案很重要需要單獨的拷貝到自己需要做鏡像的目錄下,如果沒有這個檔案的話,會認為CD光牒沒有準備好,會報媒體錯誤!
[[email protected] store_new]# cat .discinfo
1384196515.415715
Red Hat Enterprise Linux 6.5
x86_64
1
其中Red Hat Enterprise Linux 6.5聲明系統版本,1表示該系統使用了1個CD光牒
前面的工作做完,接下來就是配置kickstart.cfg檔案,該檔案是系統安裝時的參照标準,該檔案需要放在custom目錄下
[[email protected] custom]# ls
kickstart.cfg mlnx udev
[[email protected] custom]# cat kickstart.cfg
#platform=x86, AMD64, or Intel EM64T
#version=DEVEL
# Firewall configuration
firewall --disabled
# Install OS instead of upgrade
install
# Use network installation
url --url=http://192.168.111.130/cdrom/ #這個選項告訴安裝程式:到伺服器192.168.111.130 的HTTP根目錄下的cdrom 檔案夾下尋找安裝媒體
# Root password

# Clear the Master Boot Record

# Partition clearing information
clearpart --all --initlabel
# Disk partitioning information
part / --fstype="ext4" --grow --size=1
part swap --fstype="swap" --size=1024
%packages
@base
%end
大家可以拷貝這個kickstart.cfg檔案或者把系統的anaconda-ks.cfg檔案拷貝為kickstart.cfg檔案修改一下裡面的參數就可以使用了
%post是安裝完系統後執行的腳本,一些自己需求的配置可以在這裡執行
配置isolinux/isolinux.cfg
[[email protected] store_new]# cat isolinux/isolinux.cfg

封裝系統:
mkisofs -R -b isolinux/isolinux.bin -input-charset utf-8 -c isolinux/boot.cat -V RHEL6.5 -no-emul-boot -boot-load-size 4 -boot-info-table -o /root/rhel6.5store.iso .
如此一個自定義的自動安裝系統完成了
