WordPress requires access to a MySQL database to store information. So you need a database.
You can create a new database if:
- You do not have one already created on the server.
- The company that offers you hosting service give you access to manage the creation and configuration of a database.
It is not essential to create a new database for each installation of WordPress.
If you intend to use the same database for multiple WordPress installations, be sure to edit the wp-config.php file to ensure that each installation has a unique prefix database table.
$table_prefix = ‘wp_’;
If you configure a new database to a new blog, edit wp-config.php, and make sure to have the right information for the database.
