3. Enter the database, enter: use mysql;

4. View root user information: select host, user, authentication_string, plugin from user;

5. Update the root user information and set the password to an empty string: update user set authentication_string='' where user='root';

The third step is to exit mysql; comment out the skip-grant-tables at the end of the /etc/my.cnf file; restart: sudo service mysqld restart
