[系统运维]centos7.5重启网络服务，网卡ip先显示后消失

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.

具体现象如图所示：

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 netwok
