安装完Centos7系统，网卡命名跟之前发生了变化，例如！

就是看着不爽也不会影响使用，只是个网卡名称而已。

eno16777736

先编辑网卡的配置文件将里面的NAME DEVICE项修改为eth0

vim /etc/sysconfig/network-scripts/ifcfg-eno16777736

重命名该配置文件。

[root@localhost yum.repos.d]# cd /etc/sysconfig/network-scripts/
[root@localhost network-scripts]# mv ifcfg-eno16777736 ifcfg-eth0

3.
禁用该可预测命名规则。对于这一点，你可以在启动时传递“net.ifnames=0 biosdevname=0 ”的内核参数。这是通过编辑/etc/default/grub并加入“net.ifnames=0 biosdevname=0 ”到GRUBCMDLINELINUX变量来实现的。

[root@localhost network-scripts]# vim /etc/default/grub

运行命令grub2-mkconfig -o /boot/grub2/grub.cfg 来重新生成GRUB配置并更新内核参数。

[root@localhost network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg

5.重新启动机器，启动完之后网卡名称就变成了Eth0

[root@localhost network-scripts]# init 6

重启完之后，验证！

重启系统，验证！

技术一般水平有限还望以后大家多多指点！
