定制自动化安装盘

# 安装所需要的软件包:
 

复制代码
代码如下:
yum -y install createrepo mkisofs isomd5sum

# 生成精简后的rpm列表
 

复制代码
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

复制代码
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:

基于Kisckstart的安装

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


复制代码
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
