centos7 ---network.service 网络服务没法启动

配置ip地址, 重启网络服务时报错:

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

network 与 NetworkManager 服务可能会发生冲突, 致使 network 服务没法启动, 能够停用 NetworkManager

# 中止 NetworkManager 系统服务
systemctl stop NetworkManager

# 禁用该服务
systemctl disable NetworkManager

这时能够重启 network 服务

systemctl restart network
