Centos7环境将网卡地址修改为eth0

#!/bin/bash


#1. 修改grub配置文件
sed -i.bak 's/quiet/quiet net.ifnames=0 biosdevname=0/g' /etc/default/grub

#/etc/sysconfig/grub与/etc/default/grub路径内容一样
#sed -i.bak 's/quiet/quiet net.ifnames=0 biosdevname=0/g' /etc/sysconfig/grub

#2. 重新生成grub配置文件
grub2-mkconfig -o /boot/grub2/grub.cfg

#3. 修改网卡配置
mv /etc/sysconfig/network-scripts/ifcfg-e* /etc/sysconfig/network-scripts/ifcfg-eth0

cat >/etc/sysconfig/network-scripts/ifcfg-eth0 << EOF
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=dhcp
TYPE=Ethernet
IPADDR=
NETMASK=
GATEWAY=
DNS1=
DNS2=
EOF

#4. 重启系统
