CentOS Linux解决Device eth0 does not seem to be present

故障现象:

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。

、删除/etc/udev/rules.d/70-persistent-net.rules文件,重启系统

、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HWADD
