Question 2: Failed to uninstall and reinstall MySQL?
This problem is usually caused by the related information not being completely cleared when MySQL is uninstalled.
Solution : delete the previous installation directory. If the service installation directory has not been specified separately in the previous installation, the default installation directory is " C:\Program Files\MySQL", completely delete this directory. At the same time, delete the MySQL Data directory. If the data directory has not been specified in the previous installation, the default installation directory is "C:\ProgramData\MySQL", which is generally a hidden directory. After deleting, reinstall it.
