After the system reload, the MySQL database reloads the original database

I believe it's not just me. A problem that causes the MySQL database to be unusable after reinstalling the system. Although you can reinstall a MySQL server program on your computer, how can you restore the previous database as well?

Today, I found a way to solve it.

First, the MySQL server program has a data directory that is primarily used to store information about the entities (tables, etc.) in the database and database.

Also part of the installation of the server program, you will be asked to choose the location of the data, here I put D:\MySQL datafiles.

So whenever you reinstall the MySQL server program, you also select the path where the data is stored. Then copy the files from the original data folder to the new data merge. This restores the original database.
