我在百度上看的不知道對你有沒有用，你試試吧

解決辦法：

首先，打開/etc/udev/rules.d/70-persistent-net.rules內容如下面例子所示：

# 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"

記錄下，eth1網卡的mac地址00:0c:29:50:bd:17

接下來，打開/etc/sysconfig/network-scripts/ifcfg-eth0

# vi /etc/sysconfig/network-scripts/ifcfg-eth0

將 DEVICE="eth0"? 改成? DEVICE="eth1"? ,
將 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址? HWADDR="00:0c:29:50:bd:17"

最后，重啟網絡

# service network restart
或者

# /etc/init.d/network restart

正常了。
