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:
sudo apt-get install apache2 mariadb-server php php-intl php-mbstring php-xml php-apcu php-curl php-mysql
- 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 januar 2021, the latest version of XAMPP includes PHP 8.0 (MediaWiki requires at least 8.1.0).
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 Apache webserver, som kan hentes på [$apachedownload den officielle download side]. Nginx (configuration example) is a good choice as well.
PHP
PHP er programmeringssproget, som MediaWiki er skrevet i og som kræves for at køre softwaren.
- Til den seneste stabile version af MediaWiki kræves [$phpdownload PHP version 8.1.0 eller nyere].
See the page on Compatibility for further information.
- Følgende udvidelser er påkrævet:
- The following extensions are recommended in addition to the required ones:
Bemærk, at alle disse er aktiveret i PHP som standard.
If your hosting provider provides a basic LAMP environment without these, you may need to install or enable these manually.
- In Debian/Ubuntu, the following command installs all recommended PHP extensions listed above:
sudo apt-get install php php-intl php-mbstring php-xml php-apcu php-curl
- In Debian/Ubuntu, the following command installs all recommended PHP extensions listed above:
- At hosting providers with a control panel such as cPanel, you can often use "Select PHP Version" (PHP Selector) to enable these extensions. (For example, after seeing "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.
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 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:
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.
Valgfrie krav
- ImageMagick eller GD kræves for Special:MyLanguage/Manual:Image_administration#Image_thumbnailing.
- Shell adgang kræves for at køre Maintenance scripts ; opgradering kan være mere vanskeligt uden det.
- Sending email notifications via the server itself requires a message transfer agent (MTA).
- GNU diff3 can be used to automatically resolve conflicts.
- memcached can be used for object caching.
