centos7 更改成自己想要的網路卡名稱

當我們使用 centos7 時網路卡名子過長，我們需要更改成自己想要的名字，過程如下：
1 、備份並修改/etc/default/grub

[root@controller03 ~]# cp /etc/default/grub /etc/default/grub.bk

2 、 let’s disable the predictable naming rule. For that, you can pass “net.ifnames=0” kernel parameter during boot. This is achieved by editing /etc/default/grub and adding “net.ifnames=0” to GRUB_CMDLINE_LINUX variable

[root@controller03 ~]# cat  /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 rd.lvm.lv=root_vg01/lv_01 net.ifnames=0 rhgb quiet”
GRUB_DISABLE_RECOVERY=”true”

3 、 run this command to regenerate GRUB configuration with updated kernel parameters

[root@controller03 ~]# cp /boot/grub2/grub.cfg /boot/grub2/grub.cfg.bk
[root@controller03 ~]# sudo grub2-mkconfig -o /boot/grub2/grub.cfg

4 、修改 vim  /etc/udev/rules.d/70-persistent-net.rules 根據 MAC 對應 自己想要定義的網路卡的名字

[root@controller03 ~]# cat  /etc/udev/rules.d/70-persistent-net.rules
SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”,
ATTR{address}==”52:54:00:57:1a:ef”, ATTR{type}==”1″, KERNEL==”eth*”,
NAME=”ens4″

#SUBSYSTEM==”net”, ACTION==”add”, DRIVERS==”?*”,
ATTR{address}==”52:54:00:37:dc:e0″, ATTR{type}==”1″, KERNEL==”eth*”,
NAME=”eth1″

5 、最後重啟系統即可！
