克隆之后需要修改IP、删除Mac地址、修改主机名
1.IP
因为IP存在于/etc/sysconfig/network-scripts/ifcfg-eth0
使用sed -i “linec”替换IP--line实际写具体数字
如果存在HWADDR，将删除HWADDR
2.删除Mac地址
rm -rf /etc/udev/rules.d/70-persistent-net.rules
3.永久修改主机名
vi /etc/sysconfig/network
将里面的HOSTNAME修改
4.重启网卡
service network restart
5.重启服务器
reboot

---------------
copy正常的linux时：2d、8c、9c
copy的是克隆的linux：
因为没有2.HWADDR，就不用删除2d
替换是改为7c-替换IPADDR,8c--替换GATEWAY
