###version 1.1####
if [ `whoami` = "root" ];then
echo "user:root"
else
echo "you need root."
exit

####获取IP，NETMASK，GATEWAY等信息###
read -p  "please input IPaddr:" IPaddr
read -p  "please input netmask:" Netmask
read -p  "please input gateway:" Gateway

###关闭NetworkManager###
systemctl stop NetworkManager.service
systemctl disable NetworkManager.service
echo "NetworkManager.service have stopped"

####获取两个网卡的名称和MAC####
cd /etc/sysconfig/network-scripts/
eth=`ls | grep ifcfg | grep e | awk 'NR==1'| cut -b 7-9`
eth_1=`ifconfig -a | grep $eth  | awk -F: '{print $1}' | awk 'NR==1'`
eth_2=`ifconfig -a | grep $eth  | awk -F: '{print $1}' | awk 'NR==2'`
eth_1_MAC=`ifconfig -a | grep ether | awk '{print $2}' | awk 'NR==1'`
eth_2_MAC=`ifconfig -a | grep ether | awk '{print $2}' | awk 'NR==2'`
