Centos 配置eth0 提示Device does not seem to be present

一、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]

二、解决方法一：

删除/etc/udev/rules.d/70-persistent-net.rules文件

[root@c1node01 ~]# rm -rf /etc/udev/rules.d/70-persistent-net.rules[root@c1node01 ~]# reboot ………………[root@c1node01 ~]# service network restartShutting down loopback insterface:             [OK]                         Bringing up loopback insterface:               [OK]                                            Bringing up interface eth0:                    [OK]                                                          [root@c1node01 ~]#

三、解决方法二

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

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：# mv /etc/sysconfig/network-scripts/ifcfg-eth0 sysconfig/network-scripts/ifcfg-eth1vim 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
