1. vim /etc/sysconfig/grub 编辑/etc/sysconfig/grub文件

添加 net.ifnames=0 biosname=0

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=cl/root rd.lvm.lv=cl/swap rhgb quiet net.ifnames=0 biosname=0"   #添加
GRUB_DISABLE_RECOVERY="true"

2. grub2-mkconfig -o /boot/grub2/grub.cfg 生成新的grub.cfg文件

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