System requirements:
A minimum installation requires 15 Megabytes. 60 MB is needed for a website with many contributed modules and themes installed. Keep in mind you need much more for the database, files uploaded by the users, media, backups and other files.
Web server:
Apache, Nginx, or Microsoft II.
I prefer Apache. Apache is the most commonly used web server for Drupal.
Database:
MySQL 5.0.15 or higher with PDO, PostgreSQL 8.3 or higher with PDO, SQLite 3.3.7 or higher
PHP:
Drupal 7: PHP 5.2.5 or higher (5.4 or higher recommended).
Download and Extract:
Visit: https://www.drupal.org/start and download Drupal latest version in your local PC. Extract it and also rename it as your project (Like – drupal_tutorial_project).
