Abstract

Of all the web servers on the market today, Apache is most popular

because it supplies basic web server functionality right out of the

box. Yet, many customers want a more sophisticated website, one

with SQL database functionality, search capabilities, and server-side

scripting. The complexity and interdependencies of these packages

make it difficult for independent software vendors, solution

developers, and website administrators to put together a solution.

Customizing the Apache server with additional functionality can be

complex on the Linux platform. The solutions for extending

functionality are just not obvious.

This technical guide demonstrates how to integrate PHP, MySQL,

and ht://Dig with the Apache server. Independent software vendors,

solution developers, programmers, and website administrators can

use this guide to plan and deploy advanced Apache web servers on

the Linux platform.

1 Solution Overview

This document describes how to install, configure, and deploy a sophisticated Apache website on

the Linux operating system. Such a website includes the powerful, server-side scripting language,

PHP3, access to the full-featured SQL database, MySQL and the ht://Dig search engine. All of

the software packages described in this document are open source applications.

What makes open source software so attractive? First of all, it is free. Secondly, you get copies of

the software source code, which frees you to control the software to meet your short-term and

long-term requirements.

The key points of open source software restrictions are that no one:

Distributes the product without the source code (or, a list of differences between the modified

version and the original) and a copy of all related documentation

Charges for the software itself (only for its distribution)

Can impose restriction on its distribution

For more information on licensing, refer to the regulations defined by the Open Source Initiative

organization at: http://www.opensource.org/osd.html .

1.1 Apache Web Server

Apache is more widely used than all other web servers combined. A survey by Netcraft in

September 2000 substantiates this claim. After polling over 21 million sites for web server

software usage on Internet-connected computers, they found that over 61% of all Internet

websites run on the Apache server. (For updates, see http://www.netcraft.com/survey/ ) .

Clearly, the Apache Software Foundation is meeting its goal “to provide a secure, efficient, and

extensible server that keeps its HTTP services in step with HTTP standards.”

The Apache Web Server Project homepage contains versions of the Apache server and

corresponding documentation that you can download. The official website for the Apache Web

server is http://www.apache.org/ .

Getting Support on Apache

In addition to online documentation and a list of frequently asked questions, the Apache site

maintains a number of mailing lists. To receive mail from other Apache developers about code

releases, bug fixes, security fixes, and other information, join one, such as announce@apache.org.

Locate the mailing list at http://www.apache.org/announcelist.html.

1.2 PHP3 Scripting Language

The PHP (originally Personal Home Page) scripting language supports the creation of dynamic,

customized websites. With PHP, developers embed scripts within web pages. The web server

calls PHP to perform the script operations, and then the server returns the page to the user.

Functionally, PHP and the Microsoft Active Server Page (ASP) scripting language are quite

similar.
