After two articles on installing Apache, lets take a look at installing and configuring lighttpd web server on a linux system. lighttpd (pronounced “lighty”) is a web server designed to be secure, fast, standards-compliant and flexible while having a low memory footprint.

Before installation, a few points to remember. These instruction are not for a production environment – this is for a development environment. To install the software, you need root access. You can get that using this command…

su -
[Enter root password]

or by prefixing ‘sudo‘ before each command.

Installing the Server

First install lighttpd and PHP – use your distro’s package management(yum, apt-get) system to do this.

Install lighttpd

You can use this command in Red Hat based systems(Fedora, Cent OS, etc.) to install lighttpd. Debian/Ubuntu systems might the same package name – could someone post the package name of lighttpd in the comments?

yum install lighttpd lighttpd-fastcgi

Install PHP

If you don’t have PHP, you can install it using the command…

yum install php php-cli php-common

In Debian/Ubuntu systems, the command is…

apt-get install php5-cli php5-common php5-cgi

You can make sure you have php-cgi(needed for working with lighttpd) by running this command…

php-cgi -v

Installing MySQL

If MySQL is not yet installed, use this command to install it…

yum install mysql-server php-mysql mysql mysql-libs

Debian/Ubuntu Command…

apt-get install mysql-client mysql-common mysql-server php5-mysql

Configuring lighttpd

lighttpd configuration is done by editing the text file ‘/etc/lighttpd/lighttpd.conf’.

Enable some lighttpd modules by removing the comment character(#) from the beginning of the line. I have enabled the following modules…

server.modules              = (
                                "mod_rewrite",
                                "mod_redirect",
                                "mod_access",
                                "mod_fastcgi",
                                "mod_accesslog" )

Configure lighttpd’s document root – if you already have Apache, I would recommend using the same document root as Apache(applicable for development servers only).

server.document-root        = "/var/www/"

I find it helpful to enable folder listing in my server.

## virtual directory listings
dir-listing.activate       = "enable"

Turn On FastCGI PHP Support

Now, make sure lighttpd works with PHP – first get the path of php-cgi using the command..

$ whereis php-cgi
php-cgi: /usr/bin/php-cgi #Might be different on your system.

Then add the path to the configuration file of lighttpd…

#### fastcgi module
## read fastcgi.txt for more info
## for PHP don't forget to set cgi.fix_pathinfo = 1 in the php.ini
fastcgi.server             = ( ".php" =>
                               ( "localhost" =>
                                 (
                                   "socket" => "/tmp/php.socket",
                                   "bin-path" => "/usr/bin/php-cgi"
                                 )
                               )
                            )

Make sure you uncomment the above lines by removing the ‘#’ characters.

After you are done, save the file. Time to try out the server.

Starting the lighttpd Server

First stop Apache if it is running…

/etc/init.d/httpd stop

Now start lighttpd using the command

/etc/init.d/lighttpd start

Go to your document root(/var/www) and create a php files called ‘info.php’ and put this code inside it…

<?php
phpInfo();

Now fire up a browser and go to localhost – you should see a file listing page with a ‘info.php’ in the list. Click on that link – if you see a PHP information page, your web server is setup correctly.

To make sure MySQL-PHP connection is working, install phpMyAdmin – or write a database connection script – whatever is easier for you.

Web 2.0 – almost everyone have heard the term – but few are sure about its meaning. Unfortunately, it cannot be defined easily. People in different fields have their own unique definitions for the term. In this article, I will attempt to define the term at three different level – the Philosophy, the Technology and the Design.

Disclaimer: Before anyone reacts violently to the term Web 2.0, let me make myself very clear…
Web 2.0 is an ambiguous buzz word. It has been used and abused so many times that it does not have a consistent meaning – so people are free to interpret it as they see fit. And this is how I interpret it.

Philosophy

The design philosophy of a web site can make it a Web 2.0 site. This is perhaps the key difference between a Web 1.0 site and a Web 2.0 site…

Web 1.0 is a web site where there is a one way communication between the web master to the visitor. A Web 2.0 site is a site where the visitors can communicate with each other.

For example, compare the Encyclopedia Britannica to Wikipedia. In Encyclopedia Britannica, the web master creates the content and gives it to the visitor – the visitor has no way of talking back. But in Wikipedia, the visitor create the content for other visitors.

Technology

The keyword here is “Internet as a platform”. In Web 2.0, the net became the platform rather than just a data transfer mechanism. For a simple example, when you visit a site, the videos in it come from YouTube, the images from Flickr, the search is done using Google API and you can bookmark pages using the API from del.icio.us.

Some technologies that are described as Web 2.0…

• Ajax
• Valid Markup
• Microformats
• Tagging, Tag Clouds
• APIs
• Feeds
• Mashups

Some features that makes a technology Web 2.0…

Speed

For example, Ajax makes simple tasks much faster.

Ease of Use

A good example of this is Tagging. It is a much easier approach when compared to hierarchies.

Enabling Mashups

APIs, Feeds, etc. makes this possible.

Bringing Web Apps closer to the Desktop

Ajax, AIR, etc.

Design

This is perhaps the only area where the term Web 2.0 can be defined with a reasonable level of accuracy. A site with a Web 2.0 design is one that has at least some of these elements…

Simple Design

Lots of white space

Nice Icons

Violators/Badges/Star Flashes

Big Fonts

Gradients

Reflections

Shadows

And More…
