CentOS eth0 提示Device does not seem 和Device eth1 has different MAC address than expected, ignoring

第一次碰到在VMware中安装的CentOS用ifconfig查看只有lo没有eth0,但用ifconfig -a 显示eth1和lo并且用PUTTY无法连接的问题,经百度查询,用service network restart重启网卡后显示:

[[email protected] ~]# 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]

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-eth1

vim  sysconfig/network-scripts/ifcfg-eth1

修改DEVICE="eth0" 

为DEVICE="eth1"

可删掉uuid、物理地址

然后重启网卡尝试了下发现报错又变成:Device eth1 has different MAC address than expected, ignoring.

问题原因:

配置文件里的MAC地址和实际的MAC不一样。

配置文件:含有MAC信息的配置文件是/etc/sysconfig/network-scripts/ifcfg-eth1

实际MAC:查看本机实际MAC的命令是 ifconfig eth1

发现配置文件中的MAC与实际的MAC不同

解决方法:

把配置文件中的HWADDR的MAC改成本机实际的MAC地址,保存后重启网卡后解决。
