  • Next, you need to grant the user permissions to the database by running the following command:
  • GRANT ALL PRIVILEGES ON mydatabase.* TO ‘username’@’localhost’;

You can then connect to the MySQL server by running the following command:

  • mysql -u ‘username’ -p mydatabase

where ‘username’ is the username you created and ‘password’ is the password you set.
