To install Drupal just follow these simple steps:
1. Download files

Get your domain hosted on a server (say from vpsland.com).I personally use virtual private server from a service provider like vpsland.My site is hosted on www.mplstutorial.com domain and is linked to subdirectory in the root directory.

Download Drupal archive from http://drupal.org/files/projects/drupal-5.0.tar.gz and unpack it into the target directory.The alternate way could be download files on a local machine and transfer it to server through ftp.

a) Connect to your server using ssh client

b) Download the files from drupal.org wget http://drupal.org/files/projects/drupal-5.1.tar.gz

c) Unpack files to the directory drupal-5.0
tar -zxvf drupal-5.1.tar.gz

2. Create and initialize the database

Drupal uses Mysql database to store its content.Open command window.

cd \xampp\mysql\bin

mysql -uroot -ppassword

create database myDB;

3. Go to your browser and type www.mysite.com/install.php.Create the first login which is theadministrator's login.
