方法一：禁用该可预测命名规则
1、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。

cat
/etc/sysconfig/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=
"ipv6.disable=1 crashkernel=auto rhgb quiet net.ifnames=0 biosdevname=0"
GRUB_DISABLE_RECOVERY=
"true"

2、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。
3、reboot
方法二：修改rules文件
1、文件没有的话可以手动创建，后缀是.rules，按照顺序将MAC地址与网卡名称绑定

cat

/70-persistent-ipoib
.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.
#
# ACTION=="add", SUBSYSTEM=="net", DRIVERS=="?*", ATTR{type}=="32", ATTR{address}=="?*00:02:c9:03:00:31:78:f2", NAME="mlx4_ib3"
ACTION==
"add"
, SUBSYSTEM==

, ATTR{address}==
"?*00:0c:29:7a:1e:16"
, NAME=

2、修改网卡配置文件，配置DEVICE和NAME，并加入HWADDR
注：DEVICE、NAME和HWADDR 要和.rules 里面相对应
