Kickstart installation method of multi-system

Before studying this article I would like to be able to use the Kickstart automatic installation system, this article is in the context of my previous article modified to complete.

Implementation purpose: Kickstart can select other versions of the system when fully automatic installation.

For example: Centos66.x86 and centos66.x86_64

1. New centos66_64 and centos66_32 under Tftpboot directory

[Email protected] tftpboot]# mkdir centos66_64 centos66_32

Move the copied initrd.img Vmlinuz in the 64-bit image to the centos66_64 directory, 32-bit the same, and finally the following:

[e-mail protected] kickstart]# tree tftpboot/tftpboot/├──boot.msg #选择系统前提示信息保存文件 and will speak later ├──centos66_32 ├──centos66_64│├──initrd.img│└──vmlinuz├──pxelinux.0└──pxelinux.cfg└──defa ULT3 directories, 5 files

1.1 Modifying the default file

[[email protected] pxelinux.cfg]# less default default 1                               #默认安装系统, 1 for the back of the label 1prompt 1                                #打开提示timeout  120                           # Automatically press defaultdisplay boot.msg            after this event is not entered            #提示文件F1  boot.msgF2 options.msgF3  general.msgf4 param.msgf5 rescue.msglabel 1kernel centos66_64/vmlinuz             append ks=nfs:192.168.2.11:/kickstart/centosinstall/centos66_64/ks.cfg ksdevice= Eth0 initrd=centos65_64/initrd.imglabel 2kernel centos66_32/vmlinuzappend ks=nfs : 192.168.2.11:/kickstart/centosinstall/centos66_32/ks.cfg ksdevice=eth0 initrd=centos66_32/ Initrd.img

It is recommended to change the label to a simple number for easy input.

1.2 Hint file boot.msg, for reference, not supported in Chinese

[email protected] kickstart]# cat tftpboot/boot.msg ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ +++++ Welcome to use System Install Center ++++++++++++++++++++++++++++++please input num++++++++++++++++++++++++++++++ ++++default system centos66.x86_64+++++++++++++ centos66.x86_64-------------------------------->1 centos66.x86- ------------------------------->2+++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Ok,tftpboot modification completed.

2, modify the storage System directory

[email protected] kickstart]# ls centosinstall/centos66_32 centos66_64

Copy the 64-bit system files to centos66_64, each system directory has a ks.cfg file, and the NFS-specified path is different:

NFS--server=192.168.2.11--dir=/kickstart/centosinstall/centos66_64

3. NFS Modification

[Email protected] kickstart]# cat/etc/exports/kickstart/centosinstall/centos66_64 * (rw,sync)/kickstart/ CENTOSINSTALL/CENTOS66_32 * (Rw,sync)

4. Restart the service:

You can write a simple shell script:

[email protected] kickstart]# cat kickstart.sh #!/bin/shcase instatus)/etc/init.d/xinetd STATUS/ETC/INIT.D/DHCPD Status/etc/init.d/nfs status;; Start)/etc/init.d/xinetd START/ETC/INIT.D/DHCPD Start/etc/init.d/nfs start; Stop)/etc/init.d/xinetd STOP/ETC/INIT.D/DHCPD stop/etc/init.d/nfs stop;; Restart)/etc/init.d/xinetd RESTART/ETC/INIT.D/DHCPD restart/etc/init.d/nfs Restart; Esac

./kickstart.sh Restart

5. Testing

Boot after input: "1" return

Start installing 64-bit CentOS ... (I moved the CENTOS65 directly over).
