实验环境：
操作系统：CentOS Linux release 7.5.1804 (Core)
虚拟机：VMware 10.0.1
1.先编辑网卡的配置文件将里面的NAME DEVICE项修改为eth0
[root@localhost /]# vi /etc/sysconfig/network-scripts/ifcfg-ens33
TYPE="Ethernet"
PROXY_METHOD="none"
BROWSER_ONLY="no"
BOOTPROTO="dhcp"
DEFROUTE="yes"
IPV4_FAILURE_FATAL="no"
IPV6INIT="yes"
IPV6_AUTOCONF="yes"
IPV6_DEFROUTE="yes"
IPV6_FAILURE_FATAL="no"
IPV6_ADDR_GEN_MODE="stable-privacy"
NAME="ens33"
UUID="9f75af90-bd5d-467e-b433-216456e4a49e"
DEVICE="ens33" #修改成DEVICE="eth0"
ONBOOT="yes"
2.重命名该配置文件。
[root@localhost network-scripts]# mv ifcfg-ens33 ifcfg-eth0
3.过编辑/etc/default/grub并加入“net.ifnames=0 biosdevname=0 ”到GRUB_CMDLINE_LINUX变量来实现
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.ifname=0 biosdevname=0
GRUB_DISABLE_RECOVERY="true"
4.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
/etc/default/grub:行6: net.ifnames=0: 未找到命令
原因：加入的代码放到双引号内
GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos/root rd.lvm.lv=centos/swap rhgb quiet net.ifname=0 biosdevname=0”
[root@localhost network-scripts]# grub2-mkconfig -o /boot/grub2/grub.cfg

5.重启服务器
#shutdown -r now
检验效果：
