CentOS Linux解决Device eth0 does not seem to be present

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 vi    /etc/udev/rules.d/70-persistent-net.rules内容如下面例子所示：

# 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}=="00:11:22:33:44:55", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x1022:0x2000 (pcnet32)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="aa:bb:cc:dd:ee:ff", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

其次，分别更改NAME="eth0" 为NAME="eth1"   ,  NAME="eth1" 为NAME="eth0".

再次，reboot。

一切OK。。
