No connection could be made because the target machine actively refused it.

and this is my code where I want to connect to .nf.biz database :

Answer 1

Your MySQL server is only accepting connections on *nix socket (/var/run/mysqld/mysqld.sock if you're running Ubuntu) or for localhost only.

You have to edit your my.cnf (on Ubuntu again is located in /etc/mysql/my.cnf) and change the following:

bind-address = 0.0.0.0

And comment out the following

#skip-networking

Finally restart MySQL.

Be careful with that, if your MySQL machine is accessible from public Internet will be accepting connections from everybody!
