Assumptions

For this material to work, we have made some assumptions about your knowledge.

While we make every attempt to help the reader understand how to perform a

particular task, we limit our coverage of operating systems, web servers, PHP, and

databases, so that we might focus the majority of the content on Joomla

( http://www.joomla.org ) itself. Here are some of the assumptions we make:

• You know what Joomla is—at least enough to understand it is a CMS and it is

used to manage and deliver websites.

• You are using Joomla 1.5, not 1.0. x . If you need 1.0. x covered, please consider

purchasing the first edition of this book.

• You do not expect this material to be comprehensive. Keep in mind it’s a short

cut—not a comprehensive guide. Although we often provide pointers to

features and functionality that we do not cover in detail, it should not be

expected that we mention or cover everything. If you see something you want

to know more about, please check out the Joomla website.

• Once we provide the URL, you can locate the necessary files to download and

install for your system (Windows, Linux, Mac OS X, etc.).

• You have a user account with the necessary permissions to install and configure

these components on your machine. Although it is not required, preferably you

have root or administrative access.

• You have command line (direct, or via telnet or ssh) access to the machine you

are performing the installation on. We also assume you know how to remotely

access the machine, if necessary, and how to use the command line.

• You know how to modify filesystem permissions as needed.

• You have basic networking knowledge, such as understanding how to access

machines on your network via hostname or IP address and port numbers. This

also includes knowledge of terms such as localhost .

• You have a basic understanding of web servers (Apache, IIS, etc.), databases

(MySQL), and PHP to the point of being able to install, configure, and run

them.

Section 1: Installation, Setup, and Initial

Configuration

In 1997, eBay was barely two years old and Google was primarily a research

project for a couple of college students. How times have changed! Today's Internet

boasts online applications, services, and a plethora of tools, assets, and information

that can help anyone do pretty much anything. One area that has seen lots of

attention is the creation of websites.

It would be easy to recount the history of how initial website creation tools were

created, how they forked and evolved into development and Content Management

System (CMS) platforms, but not today. In this Short Cut, we want to talk about a

platform called Joomla that can be used to power very sophisticate websites

quickly. If you have used a commercial or homegrown CMS before, such as those

by Vignette, then Joomla will come as a welcome alternative.

The first section has you install the prerequisites and Joomla and then perform the

initial setup and configuration. With Joomla up and running you can begin setting

up your Sections and Categories, which will be used to classify your content.

You’re exposed to templates and extensions, as these two features help lay the

foundation for what is possible in terms of site functionality.

So, let’s get started.

Satisfying the Prerequisites

Before we can get started working with Joomla directly, make sure your computer

has the required software and components to run the system. It would be very easy

for us to spend numerous pages talking you through the individual installation

steps for each of the prerequisites, but in the interest of time we are going to make

some assumptions about what you already have installed. They are as follows:

• You have a web server, such as Apache’s HTTP Server

( http://httpd.apache.org ) or Microsoft Internet Information Services (IIS)

( http://www.iis.net ), to serve the pages.

• You have PHP ( http://www.php.net ), which is the web development language

that has been used to create Joomla and is required to process requests.

• You have MySQL ( http://www.mysql.com ) database, which is an open source

and freely available package.

• You have Joomla ( http://www.joomla.org ), the Content Management System

(CMS) we are covering in this Short Cut.

Figure 1-1 provides a look at this from a layout perspective, often referred to as the

stack . In the figure you can see that the Joomla architecture has several core

groups, including Templates, Languages, Components, Modules, and Mambots.

We will cover these in Section 4 of the Short Cut.

WAMP, MAMP, and LAMP—An Alternative

Before we dive into each of the individual requirements you need to run Joomla,

let us first point out there is an alternative—one of the AMP (Apache, MySQL,

and PHP) distributions. In a nutshell, so many applications need these three

components today, that people have started bundling them into a single installation

which can be run on Windows, Mac OS X, or Linux— thus the references to

WAMP ( http://www.wampserver.com ), MAMP ( http://www.mamp.info ) , and

LAMP ( http://en.wikipedia.org/wiki/LAMP_%28software_bundle%29 ). To

even further the case, there is a distribution called XAMPP

( http://www.apachefriends.org ) , which adds Perl to the mix (the second P) and

provides distributions for Linux, Windows, Mac OS X, and Solaris.

Note

For the purposes of this Short Cut, when we refer to XAMPP, you can assume we

literally mean an XAMPP distribution or any similar WAMP, MAMP, or LAMP

distributions unless otherwise specified. In general, take it to mean a distribution

with Apache HTTP Server, MySQL Database, and PHP.

From a Short Cut perspective, these distributions are definitely the way to go to get

started with Joomla. By installing one of these distributions, you can quickly meet

all the Joomla requirements without having to install and configure separate

packages. The purists in the world would rather install and configure them

individually, which is fine too. At the same time, if you are planning on running

Joomla in a production environment then you will also want to install and

configure these individually.

Web Server

Like most web-based applications, a web server is required by Joomla to handle

requests from a web browser and return the results. For many operating systems

today, a web server is provided. Mac OS X and most Linux distributions come

with a version of Apache HTTP Server, while Windows generally come with some

flavor of IIS. If you decide to use a built-in web server rather than one from

XAMPP, be sure to check your system documentation on how to configure and run

the service.

Be sure to check to make sure your web server is up and running before

proceeding. A check, by pointing your web browser to the host, will show if it is

working. If you are running your browser on the same machine you are running the

web server, then you can simply go to http://localhost to access the site. A freshly

installed Apache HTTP Server will return something like Figure 1-2.
