centos7 封装ks文件到iso
作者：互联网
一、步骤整理
1、挂载镜像
mkdir /mnt/cdrom mount -o loop CentOS-7-x86_64-Minimal-2009.iso /mnt/cdrom
2、安装工具
yum -y install anaconda createrepo mkisofs rsync syslinux
3、 同步/mnt/cdrom/下的文件到/ISO/路径下，除了Packages和repodata文件夹
/usr/bin/rsync -a --exclude=Packages/ --exclude=repodata/ /mnt/cdrom/ /ISO/
4、 在/ISO/文件夹下新建Packages和repodata文件夹
mkdir -p /ISO/{Packages,repodata}
5、cp 全部 rpm 包
# 以下内容为，缩减rpm包数量，减少不必须的安装文件
# 问题：这类做法安装时提示--Error Checking Software Selection--导致安装失败
# 预估为安装包不完整，当把/mnt/cdrom/Packages下全部的rpm包放到/ISO/Packages中，安装完成
cat > copy_rpm.sh <<EOF
#!/bin/bash
cd /root
rpm -qa > package.txt
DVD='/mnt/cdrom/Packages'
NEW_DVD='/ISO/Packages'
while read LINE
do
cp \${DVD}/\${LINE}*.rpm /\${NEW_DVD} || echo "\$LINE don't cp......."
done < package.txt
rm -rf package.txt
EOF
chmod +x copy_rpm.sh
./copy_rpm.sh
# 全部rpm包
###定制化安装docker、ansible，把相关的离线依赖rpm包也移动到/ISO/Packages/
cp /mnt/cdrom/Packages/* /ISO/Packages/
6、制作ks文件

cp /run/install/repo/game_driver/* /mnt/sysimage/usr/bin

%end
reboot
7、更改三个文件，指定镜像标签和KS文件，都是在镜像挂载目录
修改isolinux.cfg
cd /ISO/isolinux chmod 644 isolinux.cfg vi isolinux.cfg
修改的部分内容如下：
label linux menu label ^Install moqi-CentOS7.9 kernel vmlinuz append initrd=initrd.img inst.stage2=hd:LABEL=CentOS7 inst.ks=cdrom:/isolinux/ks.cfg quiet
-
inst.ks为ks.cfg文件位置；
-
inst.stage2为安装介质位置，hd:LABEL为介质标签，例如CentOS7。这个和后续生成ISO镜像文件的命令genisoimage的参数
-V有关。 -
modprobe.blacklist=nouveau; 禁用nouveau驱动安装，用于NVIDIA驱动的安装准备工作；
-
net.ifnames=0 biosdevname=0； 用于禁用centos7的”一致性网络设备命名法”.
chmod 444 isolinux.cfg
修改 /ISO/isolinux/grub.conf
#debug --graphics default=1 splashimage=@SPLASHPATH@ timeout 60 hiddenmenu title Install CentOS 7 findiso kernel @KERNELPATH@ @ROOT@ quiet inst.ks=cdrom:/isolinux/ks.cfg initrd @INITRDPATH@ title Test this media & install CentOS 7 findiso kernel @KERNELPATH@ @ROOT@ rd.live.check quiet initrd @INITRDPATH@
修改 /ISO/EFI/BOOT/grub.cfg
### BEGIN /etc/grub.d/10_linux ###
menuentry 'Install CentOS 7' --class fedora --class gnu-linux --class gnu --class os {
linuxefi /images/pxeboot/vmlinuz inst.ks=hd:LABEL=CentOS7:/isolinux/ks.cfg inst.stage2=hd:LABEL=CentOS7 quiet
initrdefi /images/pxeboot/initrd.img
}
8、制作comps.xml文件
cp /mnt/cdrom/repodata/*-minimal-x86_64-comps.xml /ISO/comps.xml
添加定制rpm安装包

<description xml:lang="zh_TW">installation chenjianrpm sofeware</description>
<default>false</default>
<uservisible>false</uservisible>
<packagelist>
<packagereq type="default">PyYAML</packagereq>
<packagereq type="default">ansible</packagereq>
<packagereq type="default">libtomcrypt</packagereq>
<packagereq type="default">libtommath</packagereq>

<packagereq type="default">libselinux-python</packagereq>
<packagereq type="default">libselinux-utils</packagereq>
</packagelist>
</group>
omps文件以
group来区分包，以environment来区分环境，例如centos的mini版本为minimal，其核心包为core。类似于其格式，可定制自己的rpm包，建立自己的group id和name，包含自己的language及描述，最重要的是packagelist，类型default为默认的，mandatory为强制的。将定制的rpm安装包放到/ISO/Packages/中。这里需要注意rpm包的依赖性，可以通过以下命令来获得依赖，例如以下需要perl安装rpm，然后同样添加到comps.xml中
最后在minimal环境中添加定制的groupid
<environment>
<id>minimal</id>
<name>Minimal Install</name>
<name xml:lang="as">নূন্যতম ইনস্টল</name>
...
<description xml:lang="zh_CN">基本功能。</description>
<description xml:lang="zh_TW">基本功能。</description>
<display_order>5</display_order>
<grouplist>
<groupid>core</groupid>
<groupid>core</groupid>
<groupid>chenjianrpm</groupid>
</grouplist>
</environment>
由comps.xml生成repodata包。注意当有新包加入，或者更新comps.xml文件，均需要重新生成repodata文件夹
cd /ISO createrepo -g comps.xml . Spawning worker 0 with 17 pkgs Spawning worker 1 with 17 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete
9、制作ISO文件
genisoimage -joliet-long -V CentOS7 -o CentOS7-moqi-v2.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -cache-inodes -T -eltorito-alt-boot -e images/efiboot.img -no-emul-boot /ISO/
10、Hybird模式
采用“hybird模式”（混合模式），操作系统可以直接刻录成物理光盘，也可以直接做成可引导的U盘。
isohybrid -v CentOS7-moqi-v2.iso
二、可用案例
#version=DEVEL # System authorization information auth --enableshadow --passalgo=sha512 # Use CDROM installation media cdrom # Use graphical install graphical # Run the Setup Agent on first boot firstboot --enable ignoredisk --only-use=sda # Keyboard layouts keyboard --vckeymap=us --xlayouts='us' # System language lang en_US.UTF-8 # Network information network --bootproto=static --device=ens33 --gateway=192.168.40.254 --ip=192.168.40.118 --nameserver=114.114.114.114 --netmask=255.255.255.0 --ipv6=auto --activate ##指定网卡静态IP信息 network --hostname=moqi # Root password rootpw 1qazXSW2 # System services
