Log in to MySQL first.

Take windows as an example:

1. Shut down the running MySQL service.

two。 Open the DOS window and change to the mysql\ bin directory.

3. Enter mysqld-skip-grant-tables to enter. -skip-grant-tables means to skip authorization table authentication when starting the MySQL service.
