sudo vi /etc/udev/rules.d/70-persistent-net.rules


# This is a sample udev rules file that demonstrates how to get udev to
# set the name of IPoIB interfaces to whatever you wish.  There is a
# 16 character limit on network device names though, so don't go too nuts
#
# Important items to note: ATTR{type}=="32" is IPoIB interfaces, and the
# ATTR{address} match must start with ?* and only reference the last 8
# bytes of the address or else the address might not match on any given
# start of the IPoIB stack
#
# Note: as of rhel7, udev is case sensitive on the address field match
# and all addresses need to be in lower case.

#ip link 发现网卡名称改变：

sudo vi /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="biosdevname=0"
GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"


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

sudo reboot
