At this point things might get a little tricky for the novice, but I have faith in you so pay close attention and we’ll get you through the next step. Inside the control panel on your web host will be a link to MySQL Databases. WordPress is built on a SQL database – every post, title, comment, category and tag is stored into a record in this database and that text is dynamically called upon via php code to render the blog (don’t worry if that didn’t make much sense, sometimes I get carried away). So now you are within the MySQL section of your control panel on your web host – now it’s time to create a database. You will need to remember the name of the database, the username and the password. This information will be necessary in the next step of the process.
It’s time to jump back to your FTP client and edit the wp-config-sample.php file. The first step will be renaming the file by right clicking /rename, followed by right clicking and choosing edit. This should open a text editor (notepad is my personal favorite) and allow you to change the fields. If you are confused about any of the fields, WordPress.org has put together this handy guide here.
