redhat linux下更改网卡逻辑名的脚本

chinaab

　　#!/bin/bash
#this scripts will change your network card logic name!
#copy this scrips input your /bin,named with changnet.sh
#chmod +x /bin/changnet.sh
#usage:changnet.sh firstcardnumber  secendcardnumber
#create date:2010/8/18
#auth:Jarson(at)gmail.com
#stop nic
ifdown eth$1
ifdown eth$2
#rename network card configure file !
cd /etc/sysconfig/network-scripts
sed -i -e "s/eth$1/eth$2/" ifcfg-eth$1
sed -i -e "s/eth$2/eth$1/" ifcfg-eth$2
mv ifcfg-eth$1 ifcfg-eth$2.tmp
mv ifcfg-eth$2  ifcfg-eth$1
mv ifcfg-eth$2.tmp ifcfg-eth$2
#switch alias in modprobe.conf
DRIVER1=`grep eth$1 /etc/modprobe.conf|awk '{print $3}'`
DRIVER2=`grep eth$2 /etc/modprobe.conf|awk '{print $3}'`
if
[ $DRIVER1 != $DRIVER2 ]
then
sed -e "/alias eth$1/d" -e "/alias eth$2/d" /etc/modprobe.conf>/etc/modprobe.conf.tmp.1
echo "alias eth$1 $DRIVER2">>/etc/modprobe.conf.tmp.1
echo "alias eth$2 $DRIVER1">>/etc/modprobe.conf.tmp.1
rm /etc/modprobe.conf
mv /etc/modprobe.conf.tmp.1 /etc/modprobe.conf
else
:
fi
将上面的代码复制到一个文件，changnet.sh文件，将其设置成可执行。
执行的方法是  changnet.sh  0 1    （这个是将eth0改成eth1)
