service network restart 执行时报错

环境：centos7

异常：

执行 service network restart 时报错

按提示键入“systemctl status network.service” 查看报错信息

network.service - LSB: Bring up/down networking
Loaded: loaded (/etc/rc.d/init.d/network; bad; vendor preset:disabled)

解决方法：

1、执行 ip addr flush dev eth0  

因机器而异，此处执行的是 ip addr flush dev enp0s31f6

可查看 /etc/sysconfig/network-scripts/ 下的 ifcfg-xxx 文件，xxx 即上述命名中的变量

2、关闭网络管理器

systemctl stop NetworkManager

systemctl disable NetworkManager

3|、然后就可以重启网络了

systemctl start network.service

service network restart
