I was afraid to use WordPress because I thought it might be very difficult and downloaded dozens of eBooks to get me started but never actually read event one of them because of there sizes. However somehow i managed to install WordPress and that got me started to learn WordPress by itself . It was never difficult.
These setting are for WordPress.org not .com
Step 1: Download and unzip the WordPress package from http://wordpress.org/download/.
Step 2: Buy a Domain and Hosting
Step 3: Open your Web server setting panel (e.g cpanel - this will be emailed to you after buying hosting)
> Go to SQL Database Setting
> Create New Database (just name it anything)
> Add New User and Password
> Finally add user to database
> Check all privileges and save it
Step 4: Upload the WordPress files in the desired location on your web server (use web root) e.g. http://example.com/
> make permissions to 775
Step 5: Run the WordPress installation script by accessing wp-admin/install.php in a web browser.
> If you installed WordPress in the root directory, you should visit: http://example.com/wp-admin/install.php
> If you installed WordPress in its own subdirectory called blog, for example, you should visit: http://example.com/blog/wp-admin/install.php
> Configure Database settings (just add the username, user and password)
Its done ! you have installed Wordpress. for complete details visit http://codex.wordpress.org/Installing_WordPress#Using_cPanel
