grant privileges. here are some good commands to remember:
create user `airports`@`localhost` identified by 'my-password'
grant usage on airports.* to `airports`@`localhost`;
grant all privileges on `airports`.* to `airports`@`localhost`;
select user,host from mysql.user where user like 'airports';
+----------+-----------+
| User | Host |
+----------+-----------+
| airports | % |
| airports | localhost |
+----------+-----------+
flush privileges;
debugging:
select user()
select current_user()
