批量安装linux脚本

自己抽时间写了个批量安装linux操作系统的脚本，生产环境中使用过。只要将光盘或iso镜像安装好，运行脚本即可进行批量安装linux操作系统，系统centos 5.*版本都实际测试使用过，6.0以上的版本未测试，应该可以直接使用的。

自定义自己的ks.cfg文件包，能让其自动编译安装需要的软件：

#########################################################################

上文中，ks.cfg已经是个完整的，这里补充一下如何能自动编译安装软件,加到ks.cfg后面就行了：

%post --nochroot
wget ***.tar.gz
tar xvf ***.tar.gz
cd ***
make && make install
echo "*/1 * * * * /usr/sbin/ntpdate 210.72.145.44" >>/tmp/cront.txt
crontab /tmp/cront.txt
rm -rf /tmp/cront.txt
%end
