Manual:Installation requirements/es

Además del software en sí mismo, una instalación estándar de MediaWiki tiene los siguientes requisitos:


 * Un servidor web para enviar las páginas generadas al navegador web.
 * PHP para ejecutar el software.
 * Un servidor de bases de datos para archivar las páginas y los datos.

Existen otras dependencias opcionales necesarias si quieres utilizar ciertas características avanzadas (ver más abajo).

Si tu web se encuentra en un host (es decir, si no tienes control sobre ella), contacta con los administradores del servidor o con la compañía de hosting para confirmar que estén instalados.

= == 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 MySQL database – with only one download. It is available for Linux, Windows, Mac and Solaris. As of August 2015, the latest version of XAMPP includes PHP 5.6.12 (MediaWiki requires at least ).

= == 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.

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 es el lenguaje de programación en que está escrito MediaWiki, y se necesita para ejecutar el software.

Ten en cuenta que aunque MediaWiki usa un script de instalación que establece la configuración base de los elementos más importantes, es necesario algún conocimiento de PHP para personalizaciones más detalladas.

 * Para la última versión de MediaWiki, se necesita de la versión o superior de PHP.
 * Si no eres capaz de actualizar a PHP, entonces puedes utilizar la versión de Mediawiki, ya anticuada y sin soporte, que requiere de la versión 4.3.0 o superior de PHP.
 * Se necesitan los siguientes elementos adicionales:
 * JSON (since 1.22).

Ten en cuenta que todo esto está activado en PHP por defecto. In most Debian/Ubuntu-based distros, this is in the php5-intl package.
 * MediaWiki's installer will warn if you don't have the optional PHP intl extension "to handle Unicode normalization".
 * On most Debian/Ubuntu-based distros, either the php5-mysql or php5-mysqlnd package is required if you want MediaWiki to use MySQL.
 * If you are installing MediaWiki on CentOS 5.6, use the php53 package instead of php. The php package contains PHP 5.1.x, which is not compatible with the latest version of 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).

Si necesitas compilar PHP desde código, entonces comprueba en la configuración PHP las opciones que afectan a MediaWiki.


 * Algunos servidores pueden requerir también que el módulo de base de datos equivalente y el módulo de dirección de sesión sean instalados. Mira las instrucciones del sistema operativo pertinente para más información.
 * When installing on Windows using the Microsoft installer, add the extension for your database of choice (MySQL or Postgres) to the features to be installed.

= == 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:


 * MySQL or later* or MariaDB 5.1+
 * PostgreSQL or later (supported since MediaWiki 1.8). See Manual:Installing MediaWiki for more detail.
 * SQLite 3
 * Oracle (Oracle is currently 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) or phpPgAdmin (Postgres) to help administer the database server.

MySQL 5 has been required since MediaWiki 1.19. MySQL 4 was required starting with MediaWiki 1.6. (If you are using an ancient version of MySQL and cannot upgrade then you need to use MediaWiki 1.5.8, but this version is not supported.)

= == 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 == =

Other software

 * ImageMagick or GD is required for image thumbnailing.
 * TeX is required for inline display of mathematical formulae. In most Debian/Ubuntu-based distros, this is in the texlive package.
 * Sendmail is required in order for the system to be able to send e-mails.
 * Shell access is required to run maintenance scripts; upgrading MediaWiki may be more difficult without it.

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.
