故障现象:
Linux的网卡由eth0变成了eth1，如何修复？ 解决方案:
在linux中，udev记录网络规则的脚本为：/etc/udev/rules.d/70-persistent-net.rules
如下操作：
[user@localhost ~]$ vi /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single line.
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:5a:6c:73", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:a9:22:9d", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
