System requirements

Note: this page should not be edited without first discussing the changes in a Drupal Core issue as the requirements for each version of Drupal are decided upon by the Drupal Core developers.
To install and run Drupal your web server must meet certain minimum requirements. Most web hosting companies meet these requirements. However, a few stand out by also actively supporting the Drupal community. If you need hosting, consider selecting one of these web hosts.

Disk space

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 IISMore details about web server requirements.

Database

Drupal 6: MySQL 4.1 or higher, PostgreSQL 7.1,
Drupal 7: MySQL 5.0.15 or higher with PDO, PostgreSQL 8.3 or higher with PDO, SQLite 3.3.7 or higher
Drupal 8: MySQL 5.0.15/MariaDB/Percona/equivalent or higher with PDO and an InnoDB-compatible primary storage engine, PostgreSQL 8.3 or higher with PDO, SQLite 3.3.7 or higher
Microsoft SQL Server and Oracle are supported by additional modules.More details about database requirements.

PHP

Drupal 6: PHP 5.2.x only. Warning: support for PHP 4.x has been dropped. PHP 5.3 and later may produce errors or unexpected behaviour.
Drupal 7: PHP 5.2.5 or higher (5.3 recommended).
Drupal 8: PHP 5.4 or higher.More details about PHP requirements, including PHP memory.
