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
