    sudo mysql_secure_installation
    
    # Now enter whatever lines (one at a time) to create a database and user, in this example, WordPress:
    mysql -u root -p <enterPassword>
    CREATE DATABASE wordpress;
    CREATE USER "wordpressuser"@"localhost" IDENTIFIED BY "password";
    GRANT ALL PRIVILEGES ON wordpress.* TO "wordpressuser"@"localhost" IDENTIFIED BY "password";
