To install and run Drupal 8 at your web server must meet certain minimum requirements. Most of the web hosting companies meet these 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.
Apache, Nginx, or Microsoft IIS
- MySQL 5.5.3/MariaDB 5.5.20/Percona Server 5.5.8 or higher with PDO and an InnoDB-compatible primary storage engine,
- PostgreSQL 9.1.2 or higher with PDO,
- SQLite 3.6.8 or higher
- Drupal 8: PHP 5.5.9 or higher
Now there are some basic steps to install Drupal 8:
1.Download the latest version of Drupal 8
You can download the files from https://www.drupal.org/node/2627402 and extract them into your local development manually.
2.Extract the distribution in your Apache
3.Create a database to hold the content from the site
4.Create the files directory and settings.php
Drupal will create the settings.php and services.yml files during installation, but if it can’t, it will prompt you to do so manually. If you do get this prompt, it’s highly likely that your web server does not have permissions to write to the sites/default folder.
5.Run the install script
Visit the site where you installed the files.
The first screen guides you to pick the language you want to use. Click the Save and Continue button to move on to the next step.
Next, you will choose the profile you want to install. There are two, standard and minimal.
Click on Save and Continue to move on.
Enter the database name, database user, and password for the database you created in the previous step.
The configuration will now proceed. You will see a progress bar as it works in this step. Once completed, you will see a screen with a few details to complete. These are for your site admin.
This will complete your installation and you can now visit your new Drupal site directly!
