How to restore mysql after reinstalling the system

After the system is reinstalled, how can mysql be restored? In the 2003 + 5.0 tutorial, we only need to restore the DATA directory. We can also see that many people are still unable to record the DATA directory, this will cause the wordpress database to become invalid. Thank you for installing the same version and the original directory. After stopping the database, copy all the files and start the database again.
