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
