在VMware里克隆出来的CentOS Linux。。

ifconfig...没有看到eth0.。然后重【rán hòu chóng】🔥启网卡【qǐ wǎng kǎ】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【dǎ kāi】😛/etc/udev/rules.d/70-persistent-net.rules内容如【nèi róng rú】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【wǎng kǎ de】mac地址00:0c:29:50:bd:17

接下来【jiē xià lái】，打开📢/etc/sysconfig/network-scripts/ifcfg-eth0

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

将【jiāng】🤝 DEVICE="eth0"  改成  DEVICE="eth1"  ,
将【jiāng】🤝 HWADDR="00:0c:29:8f:89:97" 改成上【gǎi chéng shàng】面的😔mac地址  HWADDR="00:0c:29:50:bd:17"

最后，重启网络

# service network restart
或者【huò zhě】😕

# /etc/init.d/network restart

正常了。
