The error is as follows. After repeated uninstallation and reinstallation, once it stops, that's it.
I tried various methods, such as modifying the attribute login, modifying the my.ini file, deleting the data to initialize the database, etc. . . .
Later, I thought that if there is an existing Mysql, install another Mysql on this machine, and the newly installed Mysql can be started and stopped at will on the service.
