CentOS Linux解决网卡启动时候报Device eth0 does not seem to be present错误

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=="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。
