CentOS Linux解决网卡报错Bringing up interface eth0.....

问题描述：
在VMware里克隆出来的CentOS Linux，开机执行命令：ifconfig...没有看到eth0网卡。然后重启网卡又报以下错误：
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内容如下面所示：

?

1 2 3 4 5 6 7 8 9 10 11 12

# 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网卡配置文件

?

1 2 3

# 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

?

1	# /etc/init.d/network restart

正常了。
