Rails：无法连接到远程MySQL数据库

Question

I have problem with connection with my remote database.

Steps, which i did:

1) In GemFile added :

gem 'mysql2'

2) in database.yml:

development:
adapter: mysql2
database: myname
username: myuser
password: mypass
host: myhost.nazwa.pl
port: 3305 

3) then in console i typed:

rake db:migrate

Communicat which i got:

Mysql2::Error: Can't connect to MySQL server on 'myhost.nazwa.pl' (4)

I wanted to try if I can connect with this database using small php script:

<?php 
$host = 'myhost.nazwa.pl';
$database = 'myname';
$username = 'myuser';
$password = 'mypass';

if ( mysql_connect($host,$username,$password) ) {
echo 'connect to mysql server *** ';
}

if ( mysql_select_db($database) ) {
echo 'open database';
}

if ( !mysql_close() ) {
echo 'cannot close connection';
exit (0);
}
?> 

And there is no problem. I can connect, create tables, add data etc.

Could you advise me something? Where can be problem? I will be very thankful. Regards :)

MySQL's default port is 3306 , and you've got 3305 in your configuration for some reason. Unless you're using a custom port, leave the port: argument out of your configuration file.
