CentOS自动化安装实战

作者:佚名 来源:网络整理 2015-8-14

   定制自动化安装盘

  # 安装所需要的软件包:

  代码如下:

  yum -y install createrepo mkisofs isomd5sum

  # 生成精简后的rpm列表

  代码如下:

  awk '/安装/{print $2}' install.log |sed 's/^[0-9]*://g' >/root/packages.list //我的是中文环境具体看log里是什么

  # 约束目录结构

  代码如下:

  mkdir -p /mnt/cdrom

  mkdir -p /data/OS

  mount /dev/cdrom /mnt/cdrom

  rsync –a --exclude=Packages /mnt/cdrom/* /data/OS

  mkdir /data/OS/Packages

  # 将精简后的rpm文件 拷贝到新的系统目录里

  # 拷贝到新的系统目录方法很多,这里省事儿就用了替换命令 但是结果都一样啊 呵呵

  复制代码

  代码如下:

  cp /mnt/cdrom/Packages/libgcc-4.4.7-3.el6.x86_64

  cp /mnt/cdrom/Packages/setup-2.8.14-20.el6.noarch

  安装软件包

  yum -y install createrepo mkisofs

  制作流程

  目录结构

  拷贝CentOS原始镜像内容,不做任何精简

  代码如下:

  mkdir /mnt/centos

  mount /dev/sr0 /mnt/centos

  mkdir /tmp/iso

  cp -r /mnt/centos/* /tmp/iso

  增加Kickstart配置文件

  文件路径和安装方式可自由定义

  生成依赖关系和ISO文件

  注意路径和命令的准确性

  代码如下:

  cd /tmp/iso

  createrepo -g repodata/*comps.xml .

  mkisofs -o /tmp/CentOS-6.4_64_auto.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -joliet-long -R -J -v -T /tmp/iso/
