Manual:Installation requirements/da

Ud over selve softwaren, forudsætter en standard MediaWiki-installation følgende systemkrav:


 * En webserver til at sende de genererede sider til din webbrowser.
 * PHP for at køre softwaren.
 * En database-server for at gemme sider og webstedsdata.

Derudover er der forskellige valgfrie krav, som er forudsat ved brug af visse avancerede funktioner (se nedenfor).

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:

Software bundles
On other operating systems, use a software bundle like XAMPP from https://www.apachefriends.org 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, the latest version of XAMPP includes PHP 8.0 (MediaWiki requires at least ).

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.

Webserver
For at sende de genererede sider til din browser, kræver MediaWiki noget webserver-software. Ofte har du ikke noget valg mellem hvilken software der skal bruges - det vil være den, der leveres af din webhotel-udbyder.

MediaWiki is broadly compatible with all major web servers that can invoke a compatible version of PHP. De fleste installationer bruger [//httpd.apache.org Apache] webserver, som kan hentes på [$apachedownload den officielle download side]. Nginx (configuration example) is a good choice as well.

PHP
PHP er programmeringssproget, som MediaWiki er skrevet i og som kræves for at køre softwaren.

See the page on for further information.
 * Til den seneste stabile version af MediaWiki kræves [$phpdownload PHP version eller nyere].

Bemærk, at alle disse er aktiveret i PHP som standard. But some host providers may only provide basic LAMP or LNMP environment. In that case you should install these extensions manually. Please take this into consideration if you plan to install MediaWiki on a shared host.
 * Følgende udvidelser er påkrævet:
 * Perl Compatible Regular Expressions (PCRE)
 * sessions
 * spl
 * openssl
 * json (MediaWiki 1.22+)
 * mbstring (required since 1.27, recommended for earlier versions)
 * fileinfo (required since 1.30)
 * intl (required since 1.36)
 * calendar (required since 1.33)
 * xml
 * If using graphical hosting control panel software such as cPanel, you can often use "Select PHP Version" (PHP Selector) to check and enable extensions. (e.g. error message: You are missing a required extension to PHP that MediaWiki requires to run. Please install: intl)
 * På Ubuntu er (bl.a.) php5-mysql pakken påkrævet, hvis du vil have MediaWiki til at bruge MySQL.
 * Some features of MediaWiki may require PHP functions that execute external processes, like image thumbnailing, that some cheap hosts usually disable.
 * 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 for compilation options that affect MediaWiki.

Database-server
MediaWiki gemmer al tekst og data (indholdssider, brugerdetaljer, systembeskeder osv.) i en database, som det er i stand til at dele med andre webbaserede applikationer (phpBB, etc.). Du skal bruge én af ​​de følgende database-servere til at køre den nyeste version af MediaWiki:


 * + eller +
 * +

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.

Hardwarekrav
De anbefalede minimumskrav er 256 MB RAM for en enkelt-computer hjemmeside og 80 MB lagerplads, selv om dette ikke vil være tilstrækkeligt til et flittigt besøgt offentligt websted eller et websted med upload aktiveret. Nogle brugere har rapporteret, at de kører MediaWiki på computere med så lidt som 48 MB 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. Se.

Valgfrie krav

 * ImageMagick eller GD kræves for.
 * TeX kræves for in-line visning af matematiske formler. In most Debian/Ubuntu-based distros, this is in the  package.
 * Shell adgang kræves for at køre ; opgradering kan være mere vanskeligt uden det.
 * via the server itself requires a message transfer agent (MTA).
 *  can be provided to automatically resolve conflicts.
 *  can be used for object caching.
