ubuntu 网卡名称重命名

ubuntu 网卡名称重命名

参考：https://blog.csdn.net/hzj_001/article/details/81587824

biosdevname 和 net.ifnames 两种命名规范
---------------------------------------
net.ifnames 的命名规范为:   设备类型+设备位置+数字

设备类型：
en 表示Ethernet
wl 表示WLAN
ww 表示无线广域网WWAN

实际的例子:
eno1 板载网卡
enp0s2  pci网卡
ens33   pci网卡
wlp3s0  PCI无线网卡
wwp0s29f7u2i2   4G modem
wlp0s2f1u4u1   连接在USB Hub上的无线网卡
enx78e7d1ea46da pci网卡

---------------------------------------

biosdevname 的命名规范为：

实际的例子:
em1 板载网卡
p3p4 pci网卡
p3p4_1 虚拟网卡

修改 grub 引导参数

# 查看 GRUB_CMDLINE_LINUX 变量
$ cat /etc/default/grub | grep GRUB_CMDLINE_LINUX

# 修改 GRUB_CMDLINE_LINUX 变量
$ sudo sed -i 's/^.*GRUB_CMDLINE_LINUX="".*$/GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"/g' /etc/default/grub

# 更新grub引导
$ sudo update-grub

# 重启系统
$ sudo reboot
