在使用vmare workstation或者vsphere的环境下安装centos7的时候，会把网卡名称默认调整为ens167，满足一致性命名，而非eth0等。有时候需要修改网卡名称，满足一般配置运维寻求
CentOS7修改网卡为eth0
.编辑网卡信息
# cd /etc/sysconfig/network-scripts/ #进入网卡目录
# mv ifcfg-eno16777728 ifcfg-eth0 #重命名网卡名称
# 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=192.168.56.12
NETMASK=255.255.255.0
GATEWAY=192.168.56.2
DNS1=192.168.56.2修改grub
[[email protected]~]# 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=autorhgb net.ifnames=0 biosdevname=0 quiet"
GRUB_DISABLE_RECOVERY="true"
[[email protected]~]# grub2-mkconfig -o /boot/grub2/grub.cfg #生成启动菜单

Done验证是否生效
[[email protected]~]# reboot #必须重启系统生效
[[email protected]~]# yum install net-tools #默认centos7不支持ifconfig 需要看装net-tools包
[[email protected]~]# ifconfig eth0 #在次查看网卡信息
