service network restart

如果出现

[root@localhost ~]# service network restar

Shutting down interface eth0:  Device eth0 has MAC address 00:0C:29:C1:30:2A, instead of configured address 00:0C:29:F6:52:E4. Ignoring.

                                                           [FAILED]

查看mac地址 cat /sys/class/net/eth0/address

编辑网卡配置文件vi /etc/sysconfig/network-scripts/ifcfg-eth0

修改HWADDR为执行cat /sys/class/net/eth0/address的结果

保存再重启网卡service network restart

[root@localhost ~]# service network restart
