四、修改 isolinux.cfg 配置文件，指定 ks 路径
注意，编辑这个文件，需要强制保存。 :wq!
[root@linuxidc ~]# vi ./iso/isolinux/isolinux.cfg
default vesamenu.c32
#prompt 1
timeout 600
display boot.msg
menu background splash.jpg
menu title Welcome to CentOS 6.5!
menu color border 0 #ffffffff #00000000
menu color sel 7 #ffffffff #ff000000
menu color title 0 #ffffffff #00000000
menu color tabmsg 0 #ffffffff #00000000

menu color hotkey 7 #ffffffff #ff000000

label linux
menu label ^Install or upgrade an existing system
menu default

append initrd=initrd.img ks=cdrom:/isolinux/ks.cfg # 仅修改这里即可

append initrd=initrd.img rescue

menu label Boot from ^local drive

append -
五、生成iso镜像，并生成 MD5校验码
## 注意所在的目录
[root@linuxidc ~]# pwd
/root
[root@linuxidc ~]# cd iso
[root@linuxidc iso]# pwd
/root/iso
[root@linuxidc iso]# mkisofs -o CentOS-6.4_64.iso -input-charset utf-8 -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -T -joliet-long /root/iso
