目录
将/mnt/下的所有文件复制到新的目录/tmp/mycentos
kickstart可以实现根据配置自动安装操作系统，本文主要讲解如何让机器读取到iso文件后自动完成操作系统的安装
将待制作的centos iso文件挂载到/mnt/目录
[root@zyq mnt]# mount CentOS-7-x86_64-Minimal-1810.iso /mnt/
将/mnt/下的所有文件复制到新的目录/tmp/mycentos
[root@zyq mnt]# cp -r /mnt/* /tmp/mycentos/
创建kickstart文件
用专门的工具自动生成kickstart文件
[root@zyq mnt]# system-config-kickstart
根据需求配置即可， 此处不一一展开，配置好的kickstart文件保存到/tmp/mycentos，文件内容如下：
[root@zyq mycentos]# cat ks.cfg
#platform=x86, AMD64, or Intel EM64T
#version=DEVEL
# Install OS instead of upgrade
install
# Keyboard layouts
keyboard 'us'
# Root password
rootpw --iscrypted $1$syqbVAdn$mnphjnVzy6uga9UJoemO91
# System language
lang en_US
# Firewall configuration
firewall --disabled
# System authorization information
auth --useshadow --passalgo=sha512
# Use CDROM installation media
cdrom
# Use graphical install
graphical
# SELinux configuration
selinux --disabled
# Do not configure the X Window System
skipx
# Reboot after installation
reboot
# System timezone
timezone Asia/Shanghai
# System bootloader configuration
bootloader --location=mbr
# Partition clearing information
clearpart --all
# Disk partitioning information
part / --fstype="xfs" --grow --size=10240
%packages

%end
%post
#!/bin/bash
touch /tmp/zyq
%end
kisckstart文件详解请参考以下连接
修改启动文件
isolinux/isolinux.cfg原文件中的内容
[root@zyq mnt]# cat isolinux/isolinux.cfg
...
label linux
menu label ^Install CentOS 7
kernel vmlinuz
append initrd=initrd.img inst.stage2=hd:LABEL=CentOS\x207\x20x86_64 quiet
...修改isolinux/isolinux.cfg中的以上内容为以下内容
[root@zyq mycentos]# cat isolinux/isolinux.cfg
...
label linux
menu label ^Install CentOS 7
kernel vmlinuz
append initrd=initrd.img inst.stage2=hd:LABEL=MYCENTOS inst.ks=hd:LABEL=MYCENTOS:/ks.cfg quiet
...“MYCENTOS”可以任意命名，后面mkisofs时候保持一致就好
重新制作ISO文件
[root@zyq mycentos]# mkisofs -o mycentos.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 -V MYCENTOS /tmp/mycentos/
genisoimage 1.1.11 (Linux)
