Node.js MySQL – Error: connect ECONNREFUSED

I use Node.js server side. I tried my code on localhost and everything works fine. I bought a server and installed Apache and node.js on it and test my web application there. I correctly changed the MySQL connection configurations from localhost to the server configurations.

I test my web application with this configuration:

var mysql      = require('mysql');
var mysqlConnection;
function new_mysqlConnection() {
    mysqlConnection = mysql.createConnection({
      host     : 'myurl.at',
      user     : 'myusername',
      database : 'mydatabase',
      password : 'mypassword'
    });
}

I start the node.js server with:

$ node server.js

When I load the page, it’s correctly displayed, but when Node.js try to connect to the database I always got the following error:

Error: connect ECONNREFUSED
    at errnoException (net.js:905:11)
    at Object.afterConnect [as oncomplete] (net.js:896:19)
