--- title: '[Kvm]Centos6自动安装镜像制作' category: Linux tag: Linux date: 2019-01-01 00:00:00 --- 制作自动化安装的 centos6 ISO镜像 # 前提以及注意事项 1. 操作环境是centos-6.10 2. 网络dhcp 3. 时区 Asia/Shanghai 4. 默认密码是: sdfsdf 5. 基于 `CentOS-6.10-x86_64-minimal.iso` 制作(从官网或者国内镜像站下载) # 环境准备 1. 安装工具 ```bash yum -y install anaconda repodata createrepo mkisofs rsync ``` 2. 创建原挂载目录, 自定义ISO目录 ```bash mkdir -p /mnt/cdrom #原ISO挂载目录 mkdir -p /data/ISO #自定义修改ISO目录 ``` 3. 挂载原ISO文件 ```bash mount -o loop CentOS-6.10-x86_64-minimal.iso /mnt/cdrom ``` 4. 拷贝原ISO文件内容到自定义目录 ```bash rsync -a --exclude=Packages/ /mnt/cdrom/ /data/ISO/ rm -rf /data/ISO/repodata mkdir -p /data/ISO/{Packages,repodata} ``` # 开始制作 1. 拷贝软件包 ```bash #!/bin/bash cd /root awk '/Installing/{print $2}' install.log | sed 's/^*://g' > package.txt PACKAGES='/mnt/cdrom/Packages' PACKDIR='/root/package.txt' NEW_PACKAGES='/data/ISO/Packages' while read LINE do cp ${PACKAGES}/${LINE}.rpm /${NEW_PACKAGES} || echo "$LINE don't cp......." done < package.txt rm -f package.txt ``` 2. 编辑 `/data/ISO/isolinux/ks.cfg` 文件 ```bash firewall --disabled install cdrom #默认的密码 rootpw --plaintext sdfsdf auth --useshadow --passalgo=sha512 keyboard us lang en_US selinux --disabled network --onboot=yes --device=eth0 --bootproto=dhcp --noipv6 skipx logging --level=info reboot timezone --isUtc Asia/Shanghai bootloader --location=mbr zerombr clearpart --all --initlabel #设置boot分区500M part /boot --fstype="ext4" --size=500 part swap --fstype="swap" --size=2048 part / --fstype="ext4" --grow --size=1 %packages --nobase @core %end reboot ``` 3. 编辑 `/data/ISO/isolinux/isolinux.cfg` 文件 ```bash default vesamenu.c32 #prompt 1 timeout 50 ##等待时间 display boot.msg menu background splash.jpg menu title Hello Centos 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 PowerSoft OS menu default kernel vmlinuz append ks=cdrom:/isolinux/ks.cfg initrd=initrd.img label vesa menu label Install system with ^basic video driver kernel vmlinuz append initrd=initrd.img xdriver=vesa nomodeset label rescue menu label ^Rescue installed system kernel vmlinuz append initrd=initrd.img rescue label local menu label Boot from ^local drive localboot 0xffff label memtest86 menu label ^Memory test kernel memtest append - ``` 4. 创建软件仓库 ```bash cd /data/ISO declare -x discinfo=$(head -1 .discinfo) cp -r /mnt/cdrom/repodata/*.xml repodata/ createrepo -g repodata/*.xml ./ ``` 5. 生成新的ISO文件 ```bash mkisofs -o CentOS-6.10-KS.iso -b /data/ISO/isolinux/isolinux.bin -c /data/ISO/isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -T ../ISO ``` 或者是下面这样制作也行 ```bash genisoimage -v -cache-inodes -joliet-long -R -J -T -V asika -o /root/centos.iso -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 . ``` 新生成的 ISO 文件存放在 /root 目录
