Codeigniter与主机的连接（数据库错误）

Question

I got this error when I was uploading my files to my host server, particularly when I started uploading my models.

SQLSTATE[HY000] [2002] Connection refused

Filename: controllers/Arena.php

Line Number: 13

I am using codeigniter as the php framework and 000webhost.com for my free hosting needs.

example of my model

<?php
class Image_model extends CI_Model{

    function get_image_data(){
        $this->load->database();

        $this->db->select('nuotrauka,id,kalba');
        $this->db->where('kalba', 'lt');
        $query = $this->db->get('events');

        return $query->result();
    }
}

my controller

<?php
class Arena extends MY_Controller{

    public function display(){

        $this->load->model('Image_model');
        $data['images'] = $this->Image_model->get_image_data();

        $this->load->view('includes/head');
        $this->load->view('includes/header', $data);
        $this->load->view('includes/footer');
    }
}

and my database.php

    $db['default'] = array(
    'dsn'  => 'mysql:host=files.000webhost.com; dbname=id692581_name; charset=utf8;',
    'hostname' => 'files.000webhost.com',
    'username' => 'id692581_username',
    'password' => 'password',
    'database' => 'id692581_name',
    'dbdriver' => 'pdo',
    'dbprefix' => '',
    'pconnect' => FALSE,
    'db_debug' => (ENVIRONMENT !== 'production'),
    'cache_on' => FALSE,
    'cachedir' => '',
    'char_set' => 'utf8',
    'dbcollat' => 'utf8_general_ci',
    'swap_pre' => '',
    'encrypt' => FALSE,
    'compress' => FALSE,
    'stricton' => FALSE,
    'failover' => array(),
    'save_queries' => TRUE
);

I'm sitting on this error for the second day and it is making me crazy

Answer 1

i used 000webhost before just change 'hostname' => 'files.000webhost.com', to the ip in phpmyadmin what i mean go to phpMyAdmin and copy the ip in page in paste it like this: 'hostname' => '164.50.60.70',

OR do this You have go to our members' area, enter the control panel and click on the 'MySQL' icon. Your MySQL hostname will be listed there.

Important! Never use 'localhost' as your MySQL hostname here or you will get access denied errors!
