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 == =

Use XAMPP from http://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 August 2016, the latest version of XAMPP includes PHP 7.0 (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.

Most installations use the Apache web server, available at the official download page. However, MediaWiki has also been tested under IIS 7.0, Cherokee, Hiawatha, LiteSpeed, nginx (configuration example), and 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.

Bemærk, at alle disse er aktiveret i PHP som standard. I Debian & Ubuntu er dette indbygget i php5-intl-pakken.
 * For the latest stable version of MediaWiki, PHP version or later is required.
 * If you are unable to upgrade to PHP, then you can use MediaWiki 1.23.13, which requires PHP version 5.3.2 or later
 * Følgende udvidelser er påkrævet:
 * Perl Compatible Regular Expressions (PCRE) (v4.0+, MediaWiki 1.23 requires PCRE 7.2+ which may not be available in earlier PHP packages)
 * Session
 * Standard PHP Library
 * JSON (since 1.22)
 * mbstring (required since 1.27, recommended for earlier versions)
 * MediaWiki's installer will warn if you don't have the optional PHP intl extension "to handle Unicode normalization".
 * På Ubuntu er (bl.a.) php5-mysql pakken påkrævet, hvis du vil have MediaWiki til at bruge MySQL.
 * Hvis du installerer MediaWiki på CentOS 5.6 skal du bruge php53 pakken i stedet for php, som indeholder PHP 5.1.x, der ikke er foreneligt med den nyeste version af MediaWiki.
 * If you are installing MediaWiki on Red Hat Enterprise Linux 6.4 (CentOS 6.4), you will need to install the php-xml package in addition to the normal php package.
 * Some features of MediaWiki may require PHP functions that execute external processes, like image thumbnailing, that some cheap hosts usually disable. This has surfaced specially in MediaWiki 1.23 on file uploads . 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 (php5-curl on Debian/Ubuntu-based distros).

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


 * Some servers may also require the equivalent database module and session management module be installed. See individual operating system instructions for more information.
 * When installing on Windows using the Microsoft installer, add the extension for your database of choice (MySQL/MariaDB or Postgres) to the features to be installed.

= == 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:


 * MySQL/da [//mysql.com eller nyere]*
 * PostgreSQL/da [//postgresql.org 8.1 eller nyere] (supporteres siden MediaWiki 1.8) Se manualen for flere detaljer.
 * 3
 * Microsoft SQL Server 2008 R2 or later is supported for LTS releases and is not guaranteed to work for non-LTS releases

Supported in the past, currently unsupported:


 * (unsupported on the latest MediaWiki versions due to open blocking bugs)

Some users find it helpful to install an additional software package such as phpMyAdmin (MySQL/MariaDB) or phpPgAdmin (Postgres) to help administer the database server.

MySQL 5 har været et krav siden MediaWiki 1.19. MySQL 4 support har været et krav siden MediaWiki 1.6. (Hvis du bruger en gammel version af MySQL og kan ikke opgradere så er du nødt til at bruge MediaWiki 1.5.8. Bemærk at denne version understøttes ikke længere.)

= == 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. See Manual:Reduce size of the installation

= == Valgfrie krav == =

Other software

 * ImageMagick eller GD kræves for image thumbnailing/da.
 * TeX kræves for in-line visning af matematiske formler. In most Debian/Ubuntu-based distros, this is in the texlive package.
 * Sendmail kræves, for at systemet skal være i stand til at sende e-mails.
 * Shell adgang kræves for at køre maintenance scripts/da, opgradering kan være mere vanskeligt uden det.

For yderligere information om de ovennævnte punkter, se installing third-party tools/da.

VisualEditor
The VisualEditor extension (and also the Flow extension) requires the Parsoid web service, which is 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.
