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.

= == Simple one-download installation == =

If you are using Linux, it's best to install apache, php and MariaDB using your package manager. On Debian and Ubuntu, do the following:

On other operating systems, use 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 have an Apple computer, you can use MAMP, which is the equivalent to XAMPP. MAMP currently 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. It is currently running the latest versions of php and MySQL.

= == 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.

De fleste installationer bruger [//httpd.apache.org Apache] webserver, som kan hentes på den officielle download side. * MediaWiki er også blevet testet under [//microsoft.com/iis IIS 6.0], [//0x50.org/ Cherokee], [//hiawatha-webserver.org/ Hiawatha], [//litespeedtech.com/litespeed-web-server-downloads.html Litespeed Standard] (kræver et trick for math/da) og [//lighttpd.net lighttpd].

= == PHP == =

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

Bemærk at selvom MediaWiki udgives med installations-script der leverer web-baseret konfiguration af de vigtigste elementer, er et vist kendskab til PHP nødvendig for mere detaljerede tilpasninger.

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. 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
 * 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 MariaDB +
 * + Se Manual:Installing MediaWiki#Postgres for flere detaljer.

Nogle brugere finder det nyttigt at installere en ekstra software pakke såsom [//phpmyadmin.net phpMyAdmin] (MySQL/MariaDB) eller [//phppgadmin.sourceforge.net phpPgAdmin] (Postgres) til at hjælpe med at administrere database-serveren.

= == 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 == =

Other software

 * 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.
 *  can be provided to automatically resolve conflicts.
 *  can be used for object caching.

Sending emails
If email notifications are enabled via, a functional configuration of a message transfer agent (MTA) is required. Common local mail transfer agent software for sending messages on Linux systems are Postfix, Sendmail, or Exim.

Once a local mail transfer agent is installed, you must set the  variable in the file   to point to the correct executable file of your mail server software. See the PHP documentation.

Alternatively you can use to connect MediaWiki to an email provider, no local mail transfer agent needed.

VisualEditor
In MediaWiki version 1.34 and earlier, the extension (and also the StructuredDiscussions extension, formerly known as "Flow") required the  web service, which was implemented using Node.js. Node.js is not provided by most shared-hosting companies (HostGator, Bluehost, Dreamhost, etc.). For performance and security reasons, it is better to use a dedicated hosting solution such as a Virtual private server ("VPS").

Scribunto
If you want to invoke Lua modules (see those on this wiki) from wiki pages and templates, your wiki will also require Scribunto.
