解决方法
1:检查网卡
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33 是不是配置正确
2.重命名网卡配置文件ifcfg-ens33为ifcfg-eth0
mv ifcfg-ens33 ifcfg-eth0
3.编辑/etc/default/grub并加入“net.ifnames=0 biosdevname=0 ”到GRUBCMDLINELINUX变量

[root@localhost network-scripts]# vi /etc/default/grub 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 net.ifnames=0 biosdevname=0 rhgb quiet" 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。
