Centos 配置eth0 提示:Device does not seem to be present,delaying initialization. [FAILED]

manon 2017-9-11 19:11 Linux/Unix 抢沙发 259人打酱油 打开侧边栏| 关闭侧边栏
问题现象:
[root@node1 ~]# 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]


问题原因:
造成这样问题的原因更多可能是因为在虚拟机(Vmware或Vbox)中移动了Centos系统对应的文件,导致重新配置时,网卡的MAC地址变了,输入ifconfig -a, 找不到eth0......


安装完一个centos虚拟机,又拷贝一份,开机后网卡无法正常启动,报错:Device eth0 does not seem to be present, delaying initialization

解决办法-1:
[root@node1 ~]# rm -rf /etc/udev/rules.d/70-persistent-net.rules
[root@node1 ~]# reboot ………………
[root@node1 ~]# service network restart
Shutting down loopback insterface:                                                         [   OK   ]
Bringing up loopback insterface:                                                             [   OK   ]
Bringing up interface eth0:                                                                    [   OK   ]
[root@node1 ~]#

解决方法-2:

# mv /etc/sysconfig/network-scripts/ifcfg-eth0  sysconfig/network-scripts/ifcfg-eth1

# vim sysconfig/network-scripts/ifcfg-eth1 【修改DEVICE="eth0" 为DEVICE="eth1"】

# service network restart
正文部分到此结束

怎么考虑把代码抽象化, 它到底比硬编码好在哪?
使用yum给Centos安装locate搜索工具
