原因：

在CentOS系统上，目前有NetworkManager和network两种网络管理工具。如果两种都配置会引起冲突，而且NetworkManager在网络断开的时候，会清理路由，如果一些自定义的路由，没有加入到NetworkManager的配置文件中，路由就被清理掉，网络连接后需要自定义添加上去。

解决方法：

1.将networkmanager服务停了

systemctl stop NetworkManager
    systemctl disable NetworkManager
    
       
        
       
        
         1
         2

2.重启网卡，就ok了

systemctl restart network
    systemctl status network
    
       
        
       
        
         1
         2

\#查看所有已安装服务  
systemctl list-units --type=service
