Completely remove MySQL

Install the MySQL database. The final step of apply SECURITY settings always fails. Feeling very depressed. Surf the internet to find a tutorial, there are four steps, one after another, found or not. Recently found that the path over the environment variable has not been uninstalled cleanly. Perhaps I am looking for the tutorial is Win7, the system does not automatically configure the path of MySQL, need to manually configure. So record, comfort me so many times uninstall the installation.

The correct installation completion interface should be the case. But I've installed it before and it's not clean. It is easy to create the fourth step of apply SECURITY settings failure. If someone fails the second step, there may be a problem with the installation path: For example, there are Chinese, there are spaces, and so on. A different installation directory is recommended.

OK, now say how to properly uninstall MySQL.

Take the WIN10 system as an example.

Step One: Right-click My computer → select manage → select services and apps → Double-click services → stop MySQL backend service.

Step two: Shortcut keys win + X Select programs and features F (or Find "control Panel" → "Programs and Features") to uninstall the MySQL program.

Step three: Remove all files from the MySQL installation directory. Crtl+a→crtl+d

Fourth step: Open My Computer → view → check the hidden items. Then go to C drive → Open parogramdata→ delete mysql. (Delete the directory for MySQL in the C-drive Programdata hidden directory.) ）

Fifth step: Right-click My computer → select Properties → select advanced system settings → select environment variables → Double-click path→ in the system environment variable to delete D:\Program Files (x86) \mysql\bin

All done.
