Rename Network interface eth2 to eth1

電腦小知識

vi /etc/udev/rules.d/70-persistent-net.rules

You may have something like:

# PCI device 0x14e4:0x165a (tg3)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:22:19:07:90:e4″, ATTR{dev_id}=="0x0″, ATTR{type}=="1″, KERNEL=="eth*", NAME="eth0″

# PCI device 0x10ec:0x8139 (8139too)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0a:79:b8:72:7d", ATTR{dev_id}=="0x0″, ATTR{type}=="1″, KERNEL=="eth*", NAME="eth1″

# PCI device 0x10ec:0x8169 (r8169)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:24:a5:84:de:62″, ATTR{dev_id}=="0x0″, ATTR{type}=="1″, KERNEL=="eth*", NAME="eth2″

Remove the line ending with NAME="eth1″ and rename eth2 to eth1 as such:

# PCI device 0x14e4:0x165a (tg3)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:22:19:07:90:e4″, ATTR{dev_id}=="0x0″, ATTR{type}=="1″, KERNEL=="eth*", NAME="eth0″

# PCI device 0x10ec:0x8169 (r8169)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:24:a5:84:de:62″, ATTR{dev_id}=="0x0″, ATTR{type}=="1″, KERNEL=="eth*", NAME="eth1″

reboot
