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
5. Restart the system
