Answer 1

Please check the Bind address

( https://dev.mysql.com/doc/refman/5.1/en/server-options.html#option_mysqld_bind-address ) to see if you have altered the my.cnf|ini configuration file on mysql correctly.

Also if you are trying to connect using different machine then you have to create a user and grant him privileges like this to make the database available remotely

CREATE USER 'jeffrey'@'%' IDENTIFIED BY 'mypass';

GRANT ALL ON db1.* TO 'jeffrey'@'%';

Wildcard % is used to give access to any IP connecting your machine.
