If mysql The server has changed , So all direct connections mysql All applications need to change the configuration, and then package and go online , Coupling is too strong .

DNS shortcoming ： Unable to sense service downtime and fail over

How does it end ？ Through the mysql Register with the registry nacos in , The application connects directly to the configuration of the registry ,

mysql How to register ？ My general idea is ： Turn on... In the application actor monitor , Scan through scheduled tasks mysql service

What is the up, still down, If it is down Then we can modify the configuration in the registry
