centos7修改网卡名称为eth0

1.编辑网卡信息
[root@localhost~]# cd /etc/sysconfig/network-scripts/ #进入网卡目录
[root@localhost network-scripts]# mv ifcfg-eno16777728 ifcfg-eth0 #重命名网卡名称
[root@localhost network-scripts]# vim ifcfg-eth0 #编辑网卡名称eno16777728 为eth0
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
NAME=eth0  #name修改为eth0
ONBOOT=yes
IPADDR=192.168.1.12
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=192.168.1.1

2.修改grub
[root@localhost~]# vim /etc/sysconfig/grub #编辑内核信息,添加(net.ifnames=0 biosdevname=0)


GRUB_TIMEOUT=5
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="vconsole.keymap=us crashkernel=auto  vconsole.font=latarcyrheb-sun16 net.ifnames=0 biosdevname=0 rhgb quiet"
GRUB_DISABLE_RECOVERY="true"

[root@linux-node2~]# grub2-mkconfig -o /boot/grub2/grub.cfg #生成启动菜单

Done

3.验证是否修改成功
[root@localhost~]# reboot #必须重启系统生效
[root@localhost~]# ip add #查看网卡名是否是 eth0

或者安装net-tools ，使用 ifconfig命令
[root@localhost~]# yum install -y net-tools #默认centos7不支持ifconfig 需要看装net-tools包
[root@localhost~]# ifconfig eth0 #查看网卡名是否为eth0
