CentOS Linux解决Device eth0 does not seem to be present

前端之家收集整理的这篇文章主要介绍了CentOS Linux解决Device eth0 does not seem to be present前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

故障现象如下:

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",ATTR{address}=="00:0c:29:50:bd:1
7",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。
