制作centos6的启动光盘boot.iso

1、将光盘isoliunx目录复制到data/myiso目录下，ks6-mini.cfg文件复制到/data/myiso/ksdir下，结构如下：
[root@Centos6 ~]# tree /data/myiso
/data/myiso
├── isolinux
│?? ├── boot.cat
│?? ├── boot.msg
│?? ├── grub.conf
│?? ├── initrd.img
│?? ├── isolinux.bin
│?? ├── isolinux.cfg
│?? ├── memtest
│?? ├── splash.jpg
│?? ├── TRANS.TBL
│?? ├── vesamenu.c32
│?? └── vmlinuz
└── ksdir
└── ks6-mini.cfg
2 directories, 12 files

2、修改isolinux.cfg文件
cd isolinux/
vim isolinux.cfg
内存检测删掉
本地安装留下，且留作默认项（重要）
救援模式删掉
增加桌面安装
label desktop
kernel vmlinuz
append initrd=initrd.img ks=cdrom:/ksdir/ks6_desktop.cfg
增加最小化安装
label mini
kernel vmlinuz
append initrd=initrd.img ks=cdrom:/ksdir/ks6_mini.cfg 效果如下：

[root@Centos6 isolinux]# vim isolinux.cfg
default vesamenu.c32
#prompt 1
timeout 600

display boot.msg

menu background splash.jpg
menu title Welcome to CentOS 6.10!
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 unsel 0 #ffffffff #00000000
menu color hotsel 0 #ff000000 #ffffffff
menu color hotkey 7 #ffffffff #ff000000
menu color scrollbar 0 #ffffffff #00000000

label linux
menu label ^Install or upgrade an existing system
menu default
kernel vmlinuz
append initrd=initrd.img
label vesa
menu label Install system with ^basic video driver
kernel vmlinuz
append initrd=initrd.img nomodeset
label local
menu label Boot from ^local drive
localboot 0xffff
label desktop
kernel vmlinuz
append initrd=initrd.img ks=cdrom:/ksdir/ks6_desktop.cfg
label mini
kernel vmlinuz
append initrd=initrd.img ks=cdrom:/ksdir/ks6_mini.cf

3、.生成boot.iso文件
mkisofs -R -J -T -v --no-emul-boot --boot-load-size 4 --boot-info-table -V "CentOS 6.9 x86_64 boot" -b isolinux/isolinux.bin -c isolinux/boot.cat -o /root/boot.iso /data/myiso/ 效果如下：
[root@Centos6 ~]# mkisofs -R -J -T -v --no-emul-boot --boot-load-size 4 --boot-info-table -V "CentOS 6.9 x86_64 boot" -b isolinux/isolinux.bin -c isolinux/boot.cat -o /root/boot.iso /data/myiso/

4、将boot.iso文件导出系统，新开一台虚拟机，挂载boot.iso，并设置光盘引导启动，在root下可以找到 boot.iso
[root@Centos6 isolinux]# ls /root
anaconda-ks.cfg boot.iso install.log install.log.syslog
sz boot.iso到桌面，
在虚拟机电源处点击“打开电源时进入固件”，即可设置，
5、开机成功,显示我们通过isolinux.cfg修改过的菜单选项，默认本地安装，选择其他选项将进行对应系统的自动安装
