codeigniter database error while upload to cpanel

Question

I am trying to upload my codeigniter website to cpanel But, I am getting following error:

A Database Error Occurred
Unable to connect to your database server using the provided settings.
Filename: core/Loader.php
Line Number: 346

I have uploaded all my files in directory: /home/mycpanelusername/public_html/

And,

database name = mycpanelusername_db_databasename
databae username = mycpanelusername_fajs
database password = mydbpassword

and I granted all privileges to my database

My database.php file is like this:

$db['default']['hostname'] = 'http://myurl.org';
$db['default']['username'] = 'mycpanelusername_fajs';
$db['default']['password'] = 'mydbpassword';
$db['default']['database'] = 'mycpanelusername_db_databasename';
$db['default']['dbdriver'] = 'mysql';
$db['default']['dbprefix'] = '';
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = '';
$db['default']['char_set'] = 'utf8';
$db['default']['dbcollat'] = 'utf8_general_ci';
$db['default']['swap_pre'] = '';
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;

Thank you, If it's not clear please ask me

give $db['default']['hostname'] as ip address

$db['default']['hostname'] ="254.000.0.0";

Try with localhost like

$db['default']['hostname'] = 'localhost';
