1. 错误现象

报错信息如下:

No suitable device found for this connection (device lo not available because device is strictly unmanaged).

执行systemctl restart network错误信息如下:

Starting network (via systemctl):  Job for network.service failed because the control process exited with error code. See "systemctl status network.service" and "journalctl -xe" for details.

2. 解决方法

执行下列命令

chkconfig NetworkManager off
service NetworkManager stop
chkconfig network on
service network start

3. 确认排除故障

此时应该已经可以正常获取IP地址了
