首先，打开/etc/udev/rules.d/70-persistent-net.rules内容如下面例子所示： # 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, and change only the value of the NAME= key. # PCI device 0x1022:0x2000 (pcnet32) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8f:89:9 7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" # PCI device 0x1022:0x2000 (pcnet32) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:bd:1 7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" 记录下，eth1网卡的mac地址00:0c:29:50:bd:17 接下来，打开/etc/sysconfig/network-scripts/ifcfg-eth0 # vi /etc/sysconfig/network-scripts/ifcfg-eth0 将 DEVICE="eth0"  改成  DEVICE="eth1"  , 将 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址  HWADDR="00:0c:29:50:bd:17" 最后，重启网络 # service network restart 或者 # /etc/init.d/network restart 正常了。

、如果上面的不起作用     (1), ifconfig 查看HWADDR的值     (2), /etc/sysconfig/network-script/ifcfg-eth1中修改ifconfig中查出的HWADDR值；
