In addition to the MediaWiki software itself, you need:

  • PHP to run MediaWiki.

In addition, there are various optional dependencies which are required if you want to use certain advanced features (see below).

If your website is hosted (i.e. you don't have direct control over it) then contact your server administrator or hosting company to ensure these software packages are installed and available.

To run MediaWiki maintenance scripts, you will need command line access.

One-download installation

If you are using Linux, it's best to install the Apache web server, PHP, and the MariaDB database server using your package manager. On Debian and Ubuntu, do the following:

sudo apt-get install php php-apcu php-common php-intl php-json php-mbstring php-mysql php-xml mariadb-server apache2

Software bundles

On other operating systems, use a software bundle like XAMPP from to install and configure all of the important packages – Apache web server, PHP, and MariaDB – with only one download. It is available for Linux, Windows, Mac and Solaris. As of januari 2021, the latest version of XAMPP includes PHP 8.0 (MediaWiki requires at least 7.4.3).

Alternatively, if you run Mac OS, you can use MAMP, which is the equivalent to XAMPP. MAMP includes the ability to run the Apache web server and a MySQL database. It is available for both Windows and Mac, but is generally used on Mac instead of Windows.

Web server

In order to serve wiki pages to browsers, MediaWiki requires some web server software. Often you will not have a choice of which software to use – it will be the one provided by your hosting provider.

MediaWiki is broadly compatible with all major web servers that can invoke a compatible version of PHP. Most installations use the Apache HTTPD web server. Nginx (configuration example) is a good choice as well.


PHP is the programming language in which MediaWiki is written, and is required in order to run the software.

  • For the latest stable version of MediaWiki, at least PHP 7.4.3 is required.

See the page on Compatibility for further information.

MediaWIki är inte kompatibelt med 7.4.0 - 7.4.2 på grund av en relaterad bugg. Använd PHP 7.4.3+ istället. Läs ärende T246594 för mer information.
Använder du PHP8 rekommenderar vi att du använder MediaWiki 1.38.4+ eller 1.39. PHP8 används inte på Wikimedias wikier och testas därför mindre men andra grupper använder MediaWiki med PHP8 utan problem. Skulle du stöta på buggar när du använder MediaWiki med PHP8 får du gärna rapportera dem. Se ärende T248925 för mer information.
  • Normally all of these are enabled in PHP by default.

But some host providers may only provide basic LAMP or LNMP environment. In that case you should install these extensions manually.

    • In Debian/Ubuntu, the following command can install PHP and the extensions listed above: sudo apt install php php-calendar php-dom php-fileinfo php-intl php-json php-mbstring php-xml php-xmlreader
  • If using graphical hosting control panel software such as cPanel, you can often use "Select PHP Version" (PHP Selector) to check and enable extensions. (example error message: "You are missing a required extension to PHP that MediaWiki requires to run. Please install: intl")
  • On most Debian/Ubuntu-based distros the php-mysql package is required if you want MediaWiki to use MySQL.
  • Some features of MediaWiki may require PHP functions that execute external processes, like image thumbnailing, that some cheap hosts usually disable.

Please take this into consideration if you plan to install MediaWiki on a shared host.

  • MediaWiki extensions may require additional PHP features, e.g. VisualEditor requires libcurl support (php-curl on Debian/Ubuntu-based distros).

If you need to compile PHP from source, then see PHP configuration for compilation options that affect MediaWiki.

Database server

MediaWiki stores all the text and data (content pages, user details, system messages, etc.) in a database, which it is capable of sharing with other web-based applications (phpBB, etc.). You will need one of the following database servers to run the latest version of MediaWiki:

Using MariaDB or MySQL is recommended as Wikimedia uses MariaDB. Any other database servers are less tested and you may likely run into some bugs.

Sen 1.34 stöder vi inte längre användningen av Oracle och Microsoft SQL Server .

Some users find it helpful to install additional control panel software such as phpMyAdmin (MySQL/MariaDB) or phpPgAdmin (PostgreSQL) to help administer the database server. Some Webbhotell also provide such software.

Hardware requirements

The recommended minimum requirements are 256MB of RAM for a single-computer website and 85MB of storage, although this will not suffice for a busy public site or a site with uploading enabled. Some users have reported running MediaWiki on computers with as little as 48MB of RAM.

The install size can be reduced to around 50MB for a developer install and to around 26MB for a non-developer, end-user install. See Manual:Reduce size of the installation .

Optional dependencies

  • TeX is required for inline display of mathematical formulae.

In most Debian/Ubuntu-based distros, this is in the texlive package.

  • GNU diff3 can be provided to automatically resolve conflicts.
