自动生成linux网卡配置脚本分享

补充：这是对于第一次添加的网卡有效，如果需要重复添加和删除后自动配置，需要更改脚本，改为根据ip a命令的信息来修改。

复制代码

代码如下:

#!/bin/bash

#update:2013-02-25

#author:ihuotui

#version 0.1

cdate=$(date +%Y%m%d)

num=$(ifconfig -a | grep eth | wc -l)

echo “ethX=” $num >> ethX

for ((n=1;n<${num};n++))

    do

if [ -e /etc/sysconfig/network-scripts/ifcfg-eth${n} ] ; then

           sed -i /HWADDR/d /etc/sysconfig/network-scripts/ifcfg-eth${n}

ifconfig -a | grep “eth${n}” | awk {print “HWADDR=””$5″””} >> /etc/sysconfig/network-scripts/ifcfg-eth${n}

      else

touch /etc/sysconfig/network-scripts/ifcfg-eth${n}

ifconfig -a | grep “eth${n}” | awk {print “HWADDR=””$5″””} >> /etc/sysconfig/network-scripts/ifcfg-eth${n}

echo NM_CONTROLLED=””yes”” >> /etc/sysconfig/network-scripts/ifcfg-eth${n}

           echo ONBOOT=””yes”” >> /etc/sysconfig/network-scripts/ifcfg-eth${n}

echo TYPE=””Ethernet”” >> /etc/sysconfig/network-scripts/ifcfg-eth${n}

echo BOOTPROTO=””dhcp”” >> /etc/sysconfig/network-scripts/ifcfg-eth${n}

echo UUID=””2460e474-fad8-4b46-baba-da6f45ae158″${n}””” >> /etc/sysconfig/network-scripts/ifcfg-eth${n}

echo DEVICE=””eth”${n}””” >> /etc/sysconfig/network-scripts/ifcfg-eth${n}

           continue

       fi

    done
