How To Install Joomla
Installing Joomla is just as simple as installing Drupal or WordPress, but it’s still nice to have some images to help out a new webmaster. For this tutorial you should download the latest stable Joomla; for this tutorial I am using Joomla 1.0.12 but webmasters interested in the 1.0.x versions shouldn’t worry as the diferences between the installers are small.
Let’s start the tutorial:
1. Go to Joomla.org and download the latest Joomla package (the 1.0.12 or the 1.5 beta, whichever you want).
2. Log in to CPanel and click the “File Manager” icon.
3. Browse through the folders to the place where you want to install Joomla and then click on the “Upload file” link.
4. Click on “Browse”, select the Joomla package and then click the Upload button under the dialog boxes.
5. After the archive is uploaded click on its file name and then click on “Extract File Contents” link that appears in the top right part of the browser window.
6. Now it’s time to go back to the main CPanel interface and create the database. Click on the “MySQL Databases” icon.
7. Create a new database.
8. Create a new user and password from the same page.
9. Add the user to the database you created earlier.
10. Ok, now it’s time for the last part of the install. I just hope you remembered the details for the database connection 
! Go to the URL where Joomla is located, which should automatically take you to the installer.
Now, somethings might not be all green but it’s not a disaster unless it’s an important part. For example, if PHP register_globals is set to ON it might be a really big security problem so you might want to contact your hosting company and ask them if it is possible to set the register_globals to OFF.
Also, all the files and directories that are not writable should be set that way. That is done through the CPanel File Manager by clicking the file or directory that you need to change and click the “Change permissions” link that appears on the right of the browser window. To set the permissions as writable for everybody check all the boxes (CHMOD 777) and then click “Change”.
11. If you want to read the license do it now (if you don’t know what GNU/GPL is, I recommend that you do read it) and then click the “Next” button.
12. Here you enter your database details; if you are unfamiliar with Joomla I suggest you leave the “Install Sample Data” box checked – it will help you learn Joomla faster than without the data.
13. Enter a site name for your Joomla installation. Don’t worry if you get it wrong, you can hange it later on. Click “Next”.
14. On step 3 you should verify that all the data is correct and enter an administration password. Click “Next”.
15. This is the end of the installation. Before you go to the new Joomla site go back to the CPanel File Manager, browse to the Joomla folder and delete the “installation” folder (it is located at www.example.com/installation).
The last step: go to your new site and start enjoying this great content management system.
