After the launch of Drupal 8, there is now an incessant need for converting existing Drupal 7 modules to Drupal 8 compatible versions. Due to the substantial changes in Drupal 8 from its previous versions, developers find it hard and time consuming to migrate from D7 to D8. This is mainly because Drupal 8 is object oriented and much closer to an MVC (Model View Controller) architecture, Drupal is no longer a PAC (Presentation Abstraction Control) architecture framework, Drupal follows the PSR-4 folder structure in compatible with symfony component which Drupal 8 uses.
The radical changes that Drupal 8 brought forward have been reflected in Drush 7 as well. Drush 7 now uses composer to download its dependencies. Before installing Drupal 8 you must make sure that Drush 7 has been installed. This is because Drupal 8 can be downloaded and installed using Drush like in the previous versions of Drush and also, Drupal 8 only supports Drush 7. Unlike earlier versions, Drush 7 cannot be installed using "sudo apt-get install drush" nor can it be updated by running "drush self-update" because that will result in updating to Drush 6 and no more. Hence the purpose of this article.
Drush is a powerful tool to manage routine tasks in a Drupal site. Downloading, installing or enabling modules, running cron and much more can be accomplished using Drush. This is why its important to have Drush 7 before a Drupal 8 installation. Drupal 8 requires minimum version of PHP 5.4. Apache requirements haven't been mentioned, but I recommend apache2.4. After this we can begin installing Drush 7.
Installing Composer
YAML is a data serialization language which is easily readable to both humans and computers. It is for this very reason that YAML is being used in Drupal 8. YAML stands for YAML Ain't Markup Language.
