CentOS Linux解决Device eth0 does not seem to be present

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]

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==ð*&, NAME=ð0&
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM==&net&, ACTION==&add&, DRIVERS==&?*&, ATTR{address}==&00:0c:29:50:bd:1
7&, ATTR{type}==&1&, KERNEL==ð*&, NAME=ð1&

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=ð0&  改成  DEVICE=ð1&  ,
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。
