修改网卡的名称--注意：容易导致服务器连接失败

方法一：

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。

编辑

/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.

# See udev(7) for syntax.

#

# Entries are automatically added by the 75-persistent-net-generator.rules

# file; however you are also free to add your own entries.

# PCI device 0x14e4:0x1713 (tg3)

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

6", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x8086:0x4222 (iwl3945)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:1f:3c:48:70:b

1", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0"

将其中的eth0,改为eth1,保存后重启系统即可

方法二

sudo nano /etc/default/grub

找到GRUB_CMDLINE_LINUX=""

改为GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

然后sudo grub-mkconfig -o /boot/grub/grub.cfg
重启后，网卡名称果然变成了eth0和wlan0
