centos 双网卡 eth0 eth1 配置

复制了一个eth0 的网卡 内容为eth1

但是在service network restart 重启的时候

出现

　　

[root@ssc ~]# service network restart
Shutting down interface eth0:                              [  OK  ]
Shutting down loopback interface:                          [  OK  ]
Bringing up loopback interface:                            [  OK  ]
Bringing up interface eth0:  
Determining IP information for eth0... done.
                                                           [  OK  ]
Bringing up interface eth1:  Device eth1 does not seem to be present, delaying initialization.
                                                           [FAILED]

解决方法如下：

打开文件

vim /etc/udev/rules.d/70-persistent-net.rules

查看eth2 的MAC地址

将 DEVICE="eth0"  改成  DEVICE="eth1"  ,
将 HWADDR="xx:xx:xx:xx:xx:xx" 改成上面的mac地址  HWADDR="xx:xx:xx:xx:xx:xx"

重启网卡 解决
