现有一台redhat7.2操作系统，配置有双网卡绑定，但是配置不生效，经检测配置有误，做了以下三点修改后，问题解决。

1、关闭NetworkManager-dispatcher、NetworkManager两个服务的开机启动

systemctl disable NetworkManager-dispatcher.service

systemctl disable NetworkManager.service

2、停止NetworkManager-dispatcher、NetworkManager两个服务

systemctl stop NetworkManager-dispatcher.service

systemctl stop NetworkManager.service

3、启用network服务

systemctl restart network
