故障现象:
[root@c1node01 ~]# 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]
原因分析:
造成这样的原因,是因为在虚拟机(Vmware)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
我这里是因为当前虚拟机是克隆的另外一台虚拟机安装完一个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
解决办法一:
[root@c1node01 ~]# rm -rf /etc/udev/rules.d/70-persistent-net.rules
[root@c1node01 ~]# reboot
[root@c1node01 ~]# service network restart
Shutting down loopback insterface: [ OK ]
Bringing up loopback insterface: [ OK ]
Bringing up interface eth0: [ OK ]
解决办法二
# 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"
可删掉uuid、物理地址
然后重启启动网卡尝试下
