同时添加多个IP

 

#! /bin/bash
NUM=1    #计数器，可以做为相对应该的网卡名字
while read LINE
do
  echo "DEVICE=eth0:$NUM" > /etc/sysconfig/network-scripts/ifcfg-eth0:$NUM
  echo "ONBOOT=yes" >> /etc/sysconfig/network-scripts/ifcfg-eth0:$NUM
  echo "BOOTPROTO=static" >>/etc/sysconfig/network-scripts/ifcfg-eth0:$NUM
  echo "IPADDR=$LINE" >> /etc/sysconfig/network-scripts/ifcfg-eth0:$NUM
  echo "NETMASK=255.255.255.0" >> /etc/sysconfig/network-scripts/ifcfg-eth0:$NUM
  NUM=`expr $NUM + 1`
done < ip.txt
#下边为填加完后的验证，安各自人来。
if [ $? = 0 ]
then
   echo "configratulation,the IP are added successful!"
