What to do if CentOS network connection fails

It may be related to the NetworkManager package that comes with the network card, just close it.

systemctl stop NetworkManager
systemctl disable NetworkManager #(设置设置NetworkManager服务开机不启动)
service network restart
Copy after login

On CentOS systems, there are currently two network management tools: NetworkManager and network. If both are configured, conflicts will occur, and NetworkManager will clear the routes when the network is disconnected. If some customized routes are not added to the NetworkManager configuration file, the routes will be cleared and need to be customized after the network is connected. Add it.

The current version of NetworkManager on CentOS is relatively low and is more suitable for systems with desktop environments, so just keep the network service on the server, close NetworkManager, and prohibit startup.
