We will install a fresh copy of Joomla on your hosted server.
Access Needed: WHM and FTP access.
We will download and unzip the WordPress package.
Create a database for WordPress on your web server, as well as a MySQL (or MariaDB) user who has all privileges for accessing and modifying it.
(Optional) Find and rename wp-config-sample.php to wp-config.php, then edit the file (see Editing wp-config.php) and add your database information.
Upload the WordPress files to the desired location on your web server:
If you want to integrate WordPress into the root of your domain (e.g. http://example.com/), move or upload all contents of the unzipped WordPress directory (excluding the WordPress directory itself) into the root directory of your web server.
If you want to have your WordPress installation in its own subdirectory on your website (e.g. http://example.com/blog/), create the blog directory on your server and upload the contents of the unzipped WordPress package to the directory via FTP.
Run the WordPress installation script by accessing the URL in a web browser.
