可以发现网卡名称eno16777736,现在想要修改名称
/etc/sysconfig/network-scripts/ifcfg-eno16777736
打开文件，修改内部的DECIVE为eth0,保存退出
重命名，将文件ifcfg-eno16777736文件名修改为eth0
cd /etc/sysconfig/network-scripts/
mv ifcfg-eno16777736 ifcfg-eth0
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。
gedit /etc/sysconfig/grub
原内容：
GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed ‘s, release .*$,,g‘ /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet" GRUB_DISABLE_RECOVERY="true"
修改后：
GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed ‘s, release .*$,,g‘ /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet net.ifnames=0 biosdevname=0" GRUB_DISABLE_RECOVERY="true"
构建新的img文件

重新启动服务器
[root@localhost ~]# reboot
重新查看ip地址：
不要打我，我这边报Mac地址冲突，但是网上很多人这么操作是成功的，后面再尝试！
