centos8自定義光盤安裝_kickstart

1.安裝軟件包
yum install genisoimage pykickstart -y

2.新建數(shù)據(jù)目錄，復(fù)制安裝包
mount /dev/cdrom /media/cdrom
mkdir -p /data/os
rsync -a /media/cdrom/ /data/os/

cd /data/os/
cp /root/ks.cfg ./isolinux/ks.cfg

3.編寫ks文件
[root@test os]# more /data/os/isolinux/ks.cfg
#version=RHEL8
# Partition clearing information
clearpart --none --initlabel
# Use graphical install

4.驗(yàn)證ks文件
[root@test ~]# ksvalidator /root/ks.cfg

5.編輯引導(dǎo)配置文件
[root@test ~]# cat /data/os/isolinux/isolinux.cfg

label linux
?? menu label ^Install CentOS Linux 8.0.1905
?? kernel vmlinuz
?? append initrd=initrd.img inst.stage2=hd:LABEL=CentOS-8-BaseOS-x86_64 quiet

label custom
?? menu label ^Install CentOS 8 autoinstall
?? kernel vmlinuz
?? append initrd=initrd.img inst.stage2=hd:LABEL=CENTOS8 inst.ks=cdrom:/isolinux/ks.cfg

[root@test ~]# cat /data/os/EFI/BOOT/grub.cfg

menuentry 'Test this media & install CentOS Linux 8.0.1905' --class fedora --class gnu-linux --class gnu --class os {
???????? linuxefi /images/pxeboot/vmlinuz inst.stage2=hd:LABEL=CentOS-8-BaseOS-x86_64 rd.live.check quiet
???????? initrdefi /images/pxeboot/initrd.img
}
menuentry 'Install CentOS 8 custom autoinstall' --class fedora --class gnu-linux --class gnu --class os {
???? linuxefi /images/pxeboot/vmlinuz inst.ks=cdrom:/isolinux/ks.cfg inst.stage2=hd:LABEL=CENTOS8 quiet
???? initrdefi /images/pxeboot/initrd.img
???? }

6.制作iso

cd /data/os/

genisoimage -v -cache-inodes -joliet-long -R -J -T -V CENTOS8 -o /root/centos-8.0-x86_64.iso -input-charset utf-8 -c isolinux/boot.cat??? -b isolinux/isolinux.bin -no-emul-boot -boot-load-size 4 -boot-info-table -eltorito-alt-boot??? -b images/efiboot.img??? -no-emul-boot? .
