Device eth0 eth0 does not exist.

ifconfig...没有看到eth0.。然后重启网卡又报下面错误。

Ifconfig... no eth0. Then reboot the card and report the following error.

故障现象：

解决办法：

Solutions #xff1a;

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

First xff0c; opening/etc/udev/rules.d/70-persistent-net.rules as follows: xff1a;

# 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

Record #xff0c; eth1 net card mac address 00:0c:29:50:bd:17

接下来，打开/etc/sysconfig/network-scripts/ifcfg-eth0

Next #xff0c; open/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"

For DEVICE61; 34; eth034; 34; 34; 3; 34;
replace HWADR& #61; 34; 00:0c:29:8f:89:97#34; replace with mac?HWADR= 34; 00:0c:29:50:bd:17#34;

最后，重启网络

Last & #xff0c; reboot network

# service network restart
或者

# Service network restart #br/ # or

# /etc/init.d/network restart

正常了。

Normal.
