centos7网卡报错,ip地址丢失不见等问题解决方法

问题出现:

ip地址丢失不见,网卡报错,当重启网卡时

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

按照提示输入systemctl status network.service查看报错如下

Failed to start LSB: Bring up/down networking.

 

解决办法:

系统自带的NetworkManager这个管理套件出错，关掉.

关掉方法:

systemctl stop NetworkManager

systemctl disable NetworkManager

重新启动网络：

systemctl start network.service
