这个方法用于解决Ubuntu下更换网卡后,新网卡变更为eth1,并且源网卡的名称eth0,无法给新网卡用的情况。也可以用于为网卡更名。
网卡MAC地址改变之后,在Linux中找到网卡,新的网卡会被识别为eth1或者更为靠后的网卡写入到/etc/udev/rules.d/70-persistent-net.rules这个文件中,修改/etc/udev/rules.d/70-persistent-net.rules这个文件,将eth0的MAC地址修改为改变后的地址就可以。

/etc/udev/rules.d/70-persistent-net.rules
root@shangyuan-laptop:/etc/udev/rules.d# more 70-persistent-net.rules
# This file maintains persistent names for network interfaces.

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1e:ec:0f:79:f

# PCI device 0x8086:0x4222 (iwl3945)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1f:3c:48:70:b

将其中的eth0,改为eth1,保存后重启系统即可
