可以通过修改/etc/udev/rules.d/z25_persistent-net.rules来实现
/etc/udev/rules.d/z25_persistent-net.rules的内如如下：
# This file was automatically generated by the /lib/udev/write_net_rules
# program, probably run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single line.
# MAC addresses must be written in lowercase.
# PCI device 0x10ec:0x8139 (8139too)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:e0:4c:39:a4:99",
# PCI device 0x10ec:0x8167 (r8169)
SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:16:17:c0:a3:66",
如果更改eth0和eth1的顺序，把两个名字对换下就可以了，然后重启，很简单吧。
