定制自動化安裝盤

# 安裝所需要的軟件包:

復制代碼

代碼如下:

yum -y install createrepo mkisofs isomd5sum

# 生成精簡后的rpm列表

復制代碼

代碼如下:

awk '/安裝/{print $2}' install.log |sed 's/^[0-9]*://g' >/root/packages.list //我的是中文環境具體看log里是什么

＃約束目錄結構

復制代碼

代碼如下:

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

# 將精簡后的rpm文件拷貝到新的系統目錄里

# 拷貝到新的系統目錄方法很多,這里省事兒就用了替換命令但是結果都一樣啊呵呵

復制代碼
