- 1 Setup
- 2 Configuration
- 3 Backup
- 4 Update
- 5 Migrate
- 6 Extensions
For all configuration options in LocalSettings see http://www.mediawiki.org/wiki/Category:MediaWiki_configuration_settings.
Disable anonymous editing
To disable anonymous editing, edit LocalSetting.php. Below the line containing $wgDBpassword, add the following lines:
$wgGroupPermissions['*' ]['edit'] = false; $wgGroupPermissions['*' ]['createpage'] = false; $wgGroupPermissions['*' ]['createtalk'] = false;
These lines disallow creating and editing pages for all groups (*), it remains allowed only for logged-in users.
If you are the only editor of a wiki (otherwise security flaws!) and want to allow pictures from all over the web, add the following line to the LocalSettings.php
$wgAllowExternalImages = true;
below the line
require_once( "includes/DefaultSettings.php" );
allow searching for short terms
On a default installation of mediawiki you cannot search for words shorter than 4 characters. So a search for "foo" will not yield results. To change this, read and follow allow searching for short terms in mediawiki.
Want an article foo/bar to have a heading that links to foo? http://www.mediawiki.org/wiki/Help:Subpages or http://www.mediawiki.org/wiki/Extension:BrettCrumbs
Namespaces in Mediawiki allow you to limit searches within a group of articles, the namespace. For setting them up, see http://www.mediawiki.org/wiki/Manual:Using_custom_namespaces.
To use mediawiki with google analytics, paste the code snippet e.g. into wfRePortTiMe in GlobalFunctIons.php.
See http://renareich.com/2010/04/27/adding-facebook-like-mediawiki/, but take care: I had to replace the original quotation marks ” by quotation marks like this: ". The difference is almost invisible. But it did not work for me with the given quotation marks. Best add it below line 166 of skins/MonoBook.php
Want to open up your wiki to human beings, but not to bots? Use the Captcha plugin.
If you want to do a backup of your mediawiki installation, you need to backup the articles, the programs, the configuration files and the media file (like pictures etc.).
On the application layer:
php maintenance/dumpBackup.php --full >backup.xml
On the database layer, if your database name is wikidb:
mysqldump wikidb >wikidbdump.sql
This describes how to migrate a wiki from one computer to another. It copies the mediawiki software and the content. Let's assume your mediawiki is running on computer earth and you want to have it running on mars.
- copy your mediawiki software
- on mars, delete LocalSettings.php
- call your wiki on mars. You get the opportunity to set up your wiki.
- attention! If you use two mediawiki instances on one host, always use the same passwords for the database use
- on earth, do a backup of your content to backup.xml. Copy it to your local computer.
- log on to the wiki on mars as WikiSysop, choose Special Pages -> Import Pages and upload backup.xml.
- all pages are imported! Look for Main_Page's history, you will find an addtional version containing earth's actual main page.
- you may have to adjust upload_max_filesize in /etc/php5/apache2
