在VMware里克隆出来的[CentOS][] Linux。。

ifconfig...没有看到eth0.。然后重启网卡又报下面错误。

故障现象：

service network restart  
Shutting down loopback insterface:                                                                                                     \[  OK  \]  
Bringing up loopback insterface:                                                                                                          \[  OK  \]

Bringing up interface eth0:  Device eth0 does not seem to be present,delaying initialization.                    \[FAILED\]

![Center][]

解决办法：

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。
