一键制作kickstart无人值守安装环境

前提：插上光盘，eth0有IP，安装完后root密码：redhat

脚本：

#!/bin/sh
#
service iptables save
service iptables stop
setenforce 0
ip=`ifconfig eth0|grep -o "addr:[^[:space:]]\{1,\}"|cut -d: -f2`
ifconfig eth0 $ip/16 up
#read -t 5 -p "Enter your ip addr: " ip
if [ ! -d /meida/Packages ] ;then
mount /dev/cdrom /media &>/dev/null

rm -rf /etc/yum.repos.d/*.repo

说明：

1，安装出现下面情况说明，磁盘空间不够大

解决方案：1，换个大的。2，调整脚本的分区那几行改小点

2，安装出现下面情况说明，客户机没有分到IP，如果是用的这个脚本应该是不会的

  除非eth0原先没有IP

解决方案：给eth0一个IP，然后重新执行脚本

3，安装出现下面情况说明，分配出去的IP和服务器不在同一网段

解决方案：在填“your dhcp network:” 的时候就不要填了保持默认，重新执行脚本

这个图是因为服务器的 netmask 为 255.255.255.0 分出去的却是255.255.0.0

在centos6.5上测试过可行，每次配置挺麻烦的，收藏一下吧
