Manual:Installing MediaWiki/ca

MediaWiki s'instal·la utilitzant un script d'instal·lació interactiu amb una interfície web. Before you can run this script, you need to do a couple of things: see prerequisites or short installation guide for experts.

MediaWiki pot ser difícil d'instal·lar per a l'usuari mitjà que no té experiència amb Apache, PHP i MySQL/MariaDB. Most users who wish to use wiki software may benefit from using a free MediaWiki host or via a software bundle.

Download MediaWiki software
Download the MediaWiki tar file from the official download page.

Generally, if you're using a production environment, you want to be running the latest stable release, which is MediaWiki.

Extract the MediaWiki software
The downloaded file is in  or in   file format. You need to uncompress this archive file before use. You can uncompress the file locally (and then upload via FTP to the server) or directly on your server. Uncompressing is usually done with software such as 7-Zip (free), WinZip, WinRAR or IZArc (free) on Windows. On Linux and Mac OS X, you can uncompress the file using this command:

tar -xf mediawiki-*.tar.gz

Upload files to your server
If you have not already uploaded the files to your web server, do so now.

Upload the files to your web server's web directory either by:


 * 1) directly copying the unzipped folder or
 * 1) by using an FTP client such as FileZilla (Open Source Software, Windows, OSX and Linux) or Cyberduck (Also OSS, Windows and OSX).
 * 1) by using software already provided by your hosting service, such as the cPanel File Manager

If your upload tool has a "change file names to lowercase" option, then you must disable this.

If you installed Apache, the correct directory is specified in your  file (it's the DocumentRoot directive, typically   or ). Note: This changed in Ubuntu 14.04 with Apache 2.4.7 where the primary configuration file for Apache server settings and directories is.

If you are using a Linux or Unix server you can instead copy the files to any directory on your server and then make a symbolic link to that folder from your web server's web directory.

Rename the uploaded folder to whatever you would like to have in the URL. If your web server is running as  for example, renaming to   directory would mean you would access your wiki at. Do not use  if you want to use it as a Short URL. (And don't set up short URLs until you have run the installation script.)

Create a database
If you already have a database server and know the root password for it, the MediaWiki installation script can create a new database for you. If this is the case, you can skip to the Run the installation script section below. If you don't know the root password, for example if you are on a hosted server, you will have to create a new database now. Currently, you must use SQLite, MariaDB/MySQL or PostgreSQL to store the actual contents of your wiki. If you're unsure which database to choose, use MariaDB as it is the one best supported by MediaWiki.

SQLite
SQLite is a stand-alone database library that stores the database contents in a single file. If PHP has the  module, no further setup is required.

On the installation page, you will need to choose a database name (which can be anything) and the SQLite database directory. For the database directory, the installer will attempt to use a subdirectory outside of the document root and create it if needed. If this directory is not safe (for example, web-readable), change it manually to avoid making it accessible to everyone on the web.

MariaDB/MySQL
MediaWiki will ask you for database and user name and will attempt to create them if they don't already exist. If doing so from MediaWiki is impossible, you can do this using various control panels such as PhpMyAdmin, which are often available from shared hosts, or you may be able to use ssh to login to your host and type the commands into a MySQL prompt. See the corresponding documentation. Alternatively, contact your host provider to have them create an account for you.

If your database is not running on the same server as your web server, you need to give the appropriate web server hostname &mdash; mediawiki.example.com in the example below &mdash; as follows:

PostgreSQL
If you are using PostgreSQL, you will need to either have a database and user created for you, or simply supply the name of a PostgreSQL user with "superuser" privileges to the configuration form. Often, this is the database user named postgres.

Here's one way to do most of the setup. This is for a Unix-like system. In this example, we'll create a database named my_wiki, owned by a user named wikiuser. From the command-line, as the postgres user, perform the following steps.

createuser -S -D -R -P -E wikiuser (then enter the database password) createdb -O wikiuser my_wiki

or as superuser (default postgres) execute the following commands at the database prompt:

Beware of the list of known issues when running MediaWiki with PostgreSQL.

Run the installation script
Next, complete the installation of MediaWiki by going to the URL of your MediaWiki installation in your web browser: Follow the instructions in.
