CentOS Linux解決Device eth0 does not seem to be present

一，問題描述

在VMware裡克隆出來的CentOS Linux。。

ifconfig...沒有看到eth0.。然後重啟網卡又報下面錯誤。

故障現象：

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]

二，解決辦法

首先，打開/etc/udev/rules.d/70-persistent-net.rules內容如下面例子所示：

# 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"

記錄下，eth1網卡的mac地址00:0c:29:50:bd:17

接下來，打開/etc/sysconfig/network-scripts/ifcfg-eth0

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

將 DEVICE="eth0"  改成  DEVICE="eth1"  ,

將 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址  HWADDR="00:0c:29:50:bd:17"

最後，重啟網絡

# service network restart

或者

# /etc/init.d/network restart

正常了。

2；

刪除/etc/udev/rules.d/70-persistent-net.rules文件，重啟系統。

3；

如果上面的不起作用

(1), ifconfig 查看HWADDR的值

(2), /etc/sysconfig/network-script/ifcfg-eth1中修改ifconfig中查出的HWADDR值；
