shell脚本自动化--bond

shell没什么基础，有客户要求需实现自动化配置bond的shell脚本，自己测试了好多次。#!/bin/bash

###version 1.1####

if [ `whoami` = "root" ];then

echo "user:root"

else

echo "you need root."

exit

fi

####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'`

####写入配置文件######

#####alias###########

echo "alias bond0 bonding"  >> /etc/modprobe.d/bond0.conf

#####重启network服务####

echo "system will reboot the network....."

chkconfig network on

/etc/init.d/network restart

echo "you need to reboot your system!"
