Solve MySQL installation error: initializing database prompts an error when installing mysql

when we install MySQL database, we report an error in initializing database because MySQL has not been completely uninstalled before. We can solve it according to the following methods:

1. First stop the original MySQL service

-Right click my computer
– select “management”
– click “service”
– find MySQL
– right click to close the service

2. Enter the control panel to uninstall mysql

in the panel, right-click Mysql to uninstall, and then follow the steps prompted to uninstall

3. Go to MySQL installation directory and delete relevant files

generally, the database is on Disk C by default. Open it in the file browser, and then check the “hidden items” to open the following three files

– Program Files
– Program Files (x64)
– ProgramData

delete the MySQL directory under these three folders

4. Clean the registry and completely delete the MySQL service

Press and hold the windows key + r on the keyboard to open the command line, enter regedit to enter the registry
and find it in turn:

HKEY_ LOCAL_ MACHINE——SYSTEM——ControlSet001——services——eventlog——Application——MySQL

right click the MYSQL to delete it. If there are still the following directories:

HKEY_ LOCAL_ MACHINE——SYSTEM——ControlSet002——services——eventlog——Application——MySQL

you can also right-click to delete. If not, it will be ignored
