CentOS报错：No suitable device found for this connection device lo not available because device is strictly unmanaged

执行命令： ifup  lo  时，Centos 无法获取IP报错：No suitable device found for this connection device lo not available because device is strictly unmanaged

1. 错误现象
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
执行下面命令

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

 

3. 确认排除故障

ip  addr  

此时应该已经可以正常获取IP地址了。
