1.编辑网卡信息
[root@linux~]# cd /etc/sysconfig/network-scripts/ #进入网卡目录
[root@linux~network-scripts]# mv ifcfg-eno16777728 ifcfg-eth0 #重命名网卡名称
[root@linux network-scripts]# cat ifcfg-eth0 #编辑网卡信息
TYPE=Ethernet
BOOTPROTO=static
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
NAME=eth0 #name修改为eth0
ONBOOT=yes
IPADDR=10.70.18.21 #定义ip地址
NETMASK=255.255.255.0 #定义子网掩码
GATEWAY=10.70.18.1 #网关定义
DNS1=114.114.114.114 #DNS定义
2.修改grub
[root@linux-node2 ~]# cat /etc/sysconfig/grub #编辑内核信息,添加红色字段的
GRUB_TIMEOUT=5
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="crashkernel=auto rhgb net.ifnames=0 biosdevname=0 quiet"
GRUB_DISABLE_RECOVERY="true"
[root@linux-node2 ~]# grub2-mkconfig -o /boot/grub2/grub.cfg #生成启动菜单

3.验证是否修改成功
[root@linux-node2 ~]# reboot #必须重启系统生效
[root@linux-node2 ~]# yum install net-tools #默认centos7不支持ifconfig 需要看装net-tools包
[root@linux-node2 ~]# ifconfig eth0 #在次查看网卡信息
