Codeigniter Error Message on Live server : mysqli::real_connect(): (HY000/2002): Connection refused

I am creating a website using Codeigniter(version:3.05),php(version: 5.6.24), mysql(version: 10.1.16 mariaDB). At local server: operating system=OSX, php version=5.6.24, mysql version=10.1.16 mariaDB. At Hosting server: operating system=FreeBSD(unix), phpversion= 5.6.30, mysql version=:5.5.38-log. The site works fine on local server. But it gives error on live server as shown below.

    A PHP Error was encountered

    Severity: Warning

    Message: mysqli::real_connect(): (HY000/2002): Connection refused

    Filename: mysqli/mysqli_driver.php

    Line Number: 202

I have been checking my database file(database.php) several time, but I didn't find any error there regarding hostname,username,password, database name.

database.php file

$db['default'] = array(
        'dsn'   => '',

Try like this.For local server.

$active_group = 'default';
$query_builder = TRUE;

$db['default'] = array(
    'dsn'      => '',
    'hostname' => 'localhost',
    'username' => '<user>',
    'password' => '<password>',
    'database' => '<database>',
    'dbdriver' => 'mysqli',
    '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
);

Use 'hostname' => 'localhost' instead of 'hostname' => 'testurl.com'. Even though you upload your code on live server, hostname remains "localhost" only.

In your database.php instead of putting "localhost" try putting "127.0.0.1". This works for most of the cases.

If you still get error then post you database.php file.
