1.安装软件包

yum install genisoimage pykickstart -y

2.新建数据目录&＃xff0c;复制安装包

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.编写ks文件

[[email protected] os]# more /data/os/isoLinux/ks.cfg

4.验证ks文件

[[email protected] ~]# ksvalidator /root/ks.cfg

5.编辑引导配置文件

[[email protected] ~]# cat /data/os/isoLinux/isoLinux.cfg

label Linux

menu label ^Install CentOS Linux 8.0.1905

kernel vmlinuz

append initrd&＃61;initrd.img inst.stage2&＃61;hd:LABEL&＃61;CentOS-8-BaseOS-x86_64 quiet

label custom

menu label ^Install CentOS 8 autoinstall

kernel vmlinuz

append initrd&＃61;initrd.img inst.stage2&＃61;hd:LABEL&＃61;CENTOS8 inst.ks&＃61;cdrom:/isoLinux/ks.cfg

[[email protected] ~]# cat /data/os/EFI/BOOT/grub.cfg

menuentry &＃39;Test this media & install CentOS Linux 8.0.1905&＃39; --class fedora --class gnu-Linux --class gnu --class os {

Linuxefi /images/pxeboot/vmlinuz inst.stage2&＃61;hd:LABEL&＃61;CentOS-8-BaseOS-x86_64 rd.live.check quiet

initrdefi /images/pxeboot/initrd.img

}

menuentry &＃39;Install CentOS 8 custom autoinstall&＃39; --class fedora --class gnu-Linux --class gnu --class os {

Linuxefi /images/pxeboot/vmlinuz inst.ks&＃61;cdrom:/isoLinux/ks.cfg inst.stage2&＃61;hd:LABEL&＃61;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  .
