Manual:Installing MediaWiki/it

MediaWiki si installa con uno script di installazione interattivo web-based. Prima di poter eseguire questo script, è necessario fare un paio di cose: vedere i prerequisiti oppure la breve guida all'installatione per esperti.

Per l'utente medio che non ha esperienza con Apache, PHP e MySQL l'installazione di MediaWiki può presentare delle difficoltà. La maggior parte degli utenti che desiderano utilizzare un software wiki possono trarre beneficio dall'utilizzo di un host MediaWiki gratuit oppure attraverso un software bundle.

Download del software MediaWiki
Scaricare il file tar MediaWiki dalla pagina ufficiale di download. Generalmente, se si utilizza un ambiente di produzione, si vuole eseguire l'ultima versione stabile, che è MediaWiki.

Extract the MediaWiki software
I file scaricati sono nel formato  o. You need to uncompress this archive file before use. È possibile decomprimere il file localmente (e poi caricarlo via FTP sul server) o direttamente sul server. In Windows puoi farlo con programmi come 7-Zip (libero), WinZip, WinRAR o IZArc (libero). Su Linux e Mac OS X, puoi decomprimere il file utilizzando questo comando:

tar -xf mediawiki-*.tar.gz

Caricare i file sul server
Se non ancora sono stati caricati i file sul web server, procedere ora.

Caricare i file nella directory web del server web tramite:


 * 1) Copiando direttamente la cartella decompressa oppure
 * 2) Mediante un client FTP come FileZilla (Software open Source, Windows, OSX e Linux) o Cyberduck (OSX).
 * 3) utilizzando il software già fornito dal servizio di hosting, come cPanel File Manager

Se il tuo strumento per il caricamento ha un'opzione "modifica i nomi file in minuscolo", lo devi disabilitare.

Se hai installato Apache, la directory corretta è specificate nel tuo file  (è la direttiva DocumentRoot, tipicamente    oppure ). Nota: Questo è cambiato in Ubuntu 14.04 con Apache 2.4.7 dove il file di configurazione principale per le impostazioni del server Apache e delle directory è.

Se stai utilizzando un server Linux o Unix, puoi anche copiare i file su qualsiasi directory del server e dopo creare un link simbolico alla cartella dalla directory del server web.

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.)

This (renamed) folder will now be referred as.

Creare un 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 wikidb, 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 password) createdb -O wikiuser wikidb

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
Once all of the above steps are complete, you can complete the installation through a web browser by going to the index.php URL in your browser — check the instructions mentioned in.

The installation tool will prompt you to download the file, and to save this as.

Alternatively, you can run the command-line installer or CLI:  adding the appropriate configuration parameters.
