Before you can install any application, that is using a database,it is strongly recommended that you create a Database with the proper Username, and Password fromyour control panel.
You also need to setup the proper hostname (Please, check the bottom of this article for IMPORTANT information on hostname) for your database, more information which is available at the bottom of this article.
Failing to setup the right database settings will often result in MySQL error such as:
"Error establishing database connection" - which will be displayed in your web browser.
In order to setup your database correctly , you can use the tutorials listedbelow:
Create Database, User and Password in cPanel (Linux Accounts)
1. Database Host
2. Database Name
3. Database Username
4. Database Password
All those attributes must be specified correctly in order toproperly connect the Database to the application used.
Below you will find samples of the Connection strings of Joomla!and Wordpress, that will give you idea of a properly set configuration.
Joomla! : Connection string is located in configuration.php
public $host = 'database_host_here';
// This is the DB host
public $user = 'username_here';
// DB username
public $password = 'password_here';
// DB password
public $db = 'database_name_here';
// DB database name
WordPress : Connection string is located in wp-config.php
/** The name of the database for WordPress */
/** MySQL database username */
/** MySQL database password */
/** MySQL hostname */define('DB_HOST', 'database_host_here');
Please note that in most cases, both Linux and Windows based shared hosting plans are using External Database servers and you should NOT leave your database hostname to "localhost". For VPS/Cloud based accounts you might be able to use the default "localhost" as database server, but this needs to be verified using the information below.
For Linux based plans, you will find the EXACT Databasehostname under the Database section (Click on MySQL Databases) in cPanel control panel or Plesk panel (VPS/Cloud users using Plesk panel).
For Windows based plans, you will find the Databasehost in the Space summary or in Plesk control panel for Windows based VPS/Cloud users that are using Plesk instead of SolidCP.
