###修改网卡配置文件名称
function net () {
b0=-1
cat /proc/net/dev |grep ":" | grep -v "lo" | cut -d: -f1 | sort >> /tmp/net_name.txt
do
c0=$line
b0=`expr $b0 + 1`
mv /etc/sysconfig/network-scripts/ifcfg-$c0 /etc/sysconfig/network-scripts/ifcfg-eth$b0
##修改网卡模式为static
sed -i "s/dhcp/static/g" /etc/sysconfig/network-scripts/ifcfg-eth$b0
##删除包含IPV6的行
sed -i "/IPV6/d" /etc/sysconfig/network-scripts/ifcfg-eth$b0
##修改网卡DEVICE为eth.
sed -i "s/"$c0"/eth"$b0"/g" /etc/sysconfig/network-scripts/ifcfg-eth$b0
done < /tmp/net_name.txt
}
###重新配置grub配置并更新内核
function grub () {
sed -i "s/crashkernel=auto rhgb quiet/crashkernel=auto net.ifnames=0 biosdevname=0 rhgb quiet/g" /etc/default/grub
grub2-mkconfig -o /boot/grub2/grub.cfg
}
###修改网卡创建命名规则
function rules () {
b0=-1
/sbin/lspci | awk "/net/ || /less/ { print $1 }" | sort | while read line
do
c0=$line
b0=`expr $b0 + 1`
echo "ACTION=="add", SUBSYSTEM=="net", BUS=="pci", ID=="0000:"$c0"", NAME="eth"$b0""" >>/etc/udev/rules.d/70-persistent-net.rules
done
}
net
grub
rules
