CentOS Linux解決Device eth0 does not seem to be present

一，問題描述

在VMware裡複製出來的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

1.

首先，開啟/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:89:97", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"# PCI device 0x1022:0x2000 (pcnet32)SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:bd:17", 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，開啟/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，重啟網路# service network restart或者# /etc/init.d/network restart正常了。

2.

刪除/etc/udev/rules.d/70-persistent-net.rules檔案，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；
