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
