Joomla (TM) is among the most popular Open Source content management systems that exist today, in the company of Drupal and WordPress. If you just need to build a web site for yourself and are unfamiliar with all this HTML stuff, or you develop web sites for other people, or if you’re at the pointy end of developing web-based applications, then Joomla really should be on your evaluation list. It’s easy to install, use, and extend.

Installation
The server requirements for Joomla are fairly minimal. You need a host that supports PHP and MySQL, and an account with at least 50MB of disk space. This allows for the Joomla install, the database, and room for a bit of media. While Joomla can run on earlier versions of PHP, for security reasons your host should be running on the latest version of PHP4 (4.4.9 was the final version of PHP4 after development was halted) or PHP5. Joomla does run better on PHP5 but watch out for buggy versions like 5.0.4. The most desirable version of MySQL to use is version 4. It’s also wise to choose a host that runs PHP in CGI mode as this takes care of a great many annoying problems caused by file permissions. More information on the technical requirements is available on the Joomla web site.
You can download the latest version of Joomla from the Joomla site as well. When a new version comes out you’re able to download incremental patch packages that only contain the changed files between versions, thus saving you a little upload time and bandwidth.
Transfer the files to your server in the normal fashion, either by uploading the package and unpacking on your server, or unpacking first and then uploading all individual files (the latter takes a while). Once that’s done, that’s generally the last time you need to touch your FTP Client; the rest of the set up is done in your browser.


Point your browser to the URL of your site—including any subfolder path if required—where you unpacked all the Joomla files, http://www.example.com/joomla/.
On this screen you can select the language for the installation process (there are over 40 to choose from). Click Next and you come to the Pre-Installation Check screen.
This screen gives you an indication of whether your host has all of the required or desired settings for the Joomla site to run. Assuming all is well, click Next and you will come to the License Information screen. This screen presents you with a copy of the GNU General Public License under which the Joomla source code is released. Peruse at your leisure and click Next. This brings you to the Database Configuration screen.
This is probably the most complicated part of the process because you have to know your database credentials for the site to work properly. Often this is done using Plesk, Cpanel, phpMyAdmin, or the command line if you are a true geek. But if you’re unsure you need to ask your hosting service. I’m going to assume that you already know how to create your database and user account:
The database type is likely to be “mysql” (if you know what “mysqli” is then you probably know if you should select it).
The hostname is likely to be “localhost” but check with your hosting service or IT department.
The username and password will either have been created by you or given to you by your hosting service.
The database name is either one you have created, or if the database user account you have has permissions to create a database, then you can enter a new name.
If this is a first-time install, don’t worry about the Advanced Settings slider. It’s only needed if you are installing over the top of an existing database.
Click Next. There might be a short delay while the database scripts are run and, if no errors were encountered, you will be presented with the FTP Configuration screen. Unless you know you’re going to have problems with file permissions (from previous experience), then you can skip past this screen. Joomla’s “FTP Layer” attempts to address some file permission issues but, as stated before, if the host is running PHP in CGI mode, you’re quite safe to omit this step.
Live on the wild side and just click Next; this will bring you to the Main Configuration screen.
On this screen we set the Site Name and then the Super Administrator email address and password. We can also optionally install some sample data that will produce a fully fledged web site—to give you an example of what you can do—or your can load a migration script from the previous version of Joomla. In this example we’ll bypass loading any sample data because we want a clean site to work with.
Click Next and you’ll be taken to the Finish screen. Now, I told a lie before. You’ll have to use your FTP Client or File Manager to remove the folder called installation. This is really important because the site will fail to work otherwise. Besides, there are some unscrupulous people out there and, armed with a strong knowledge of Joomla, they could well do some nasty things to your site if you leave it there.
Opting to be lazy and just renaming the folder is unwise—make sure you delete it completely. When you have done that click the Site button. You will be presented with a fairly bland site and a Home link. We need to fix this!
