#!/bin/bash
#配置ip地址参数脚本
NET=/etc/sysconfig/network-scripts/ifcfg-ens33
if grep -E "BOOTPROTO=dhcp"  $NET
then

   read -p "请输入ip地址：" ip1
   read -p "请输入netmask：" net1
   sed "1a$ip1" $NET
   sed "2a$net1" $NET
   systemctl restart network
elif grep -E "BOOTPROTO=static" $NET
then
   read -p "请输入ip地址：" ip2
   read -p "请输入netmask：" net2
   sed -i "s/IPADDR=.*/IPADDR=$ip2/g" $NET
   sed -i "s/NETMASK=.*/NETMASK=$net2/g" $NET
echo "正在配置你所输入的IP地址，请耐心等待,一会就可以登录了亲(づ￣3￣)づ╭～"
   systemctl restart network
