Error establishing database connection

I set up database and user, I type the url

http://blog.jim.com/wp-admin/install.php

And get the response

Error establishing a database connection

* Are you sure you have the correct username and password?
* Are you sure that you have typed the correct hostname?

Yes, I am sure I have the correct username and password.

I went to cpanel/MySql Databse, created a database and user, added the user to the database, whereupon cpanel/Mysql displayed:

Database Users
echeque_Wordpress echeque_word

and my wp-config.php file says:
define(‘DB_NAME’, ‘echeque_wordpress’); // The name of the database
define(‘DB_USER’, ‘echeque_word’); // Your MySQL username
define(‘DB_PASSWORD’, ‘EpC8Q5bg’); // …and password
define(‘DB_HOST’, ‘localhost’); // 99% chance you won’t need to change this value
define(‘DB_CHARSET’, ‘utf8’);
define(‘DB_COLLATE’, ”);
