MediaWiki ist ein freies Wiki-Softwarepaket, welches für die Wikipedia geschrieben worden ist. Es wird als Grundlage der Non-Profit-Organisation der Wikimedia Foundation und viele andere Wikis genutzt, einschließlich dieser Webseite.

http://www.mediawiki.org/

Folgende Erweiterungen bzw. Konfixx waren/sind relevant:

Konfiguration

404/Seite existiert nicht

Ist ein Systemtext: MediaWiki:Noarticletext 

Diese Seite enthält momentan noch keinen Text. Du kannst sie <span class="plainlinks">[{{fullurl:{{FULLPAGENAME}}|action=edit}} bearbeiten]</span>, ihren Titel auf anderen Seiten [[Special:Search/{{PAGENAME}}|suchen]] oder die zugehörigen <span class="plainlinks">[{{fullurl:{{#special:Log}}|page={{FULLPAGENAMEE}}}} Logbücher betrachten]</span>.

Enabling subpages for a namespace

An easy way to enable subpages for a given namespace is to edit the LocalSettings.php and insert the following: 

#LocalSettings.php
# Enable subpages in the main namespace
$wgNamespacesWithSubpages[NS_MAIN] = true;

Eliminating index.php from the url

Das Wiki läuft direkt unter http://crazylinux.de/. Artikel sind damit unter /, also z.b. http://crazylinux.de/Apache2, erreichbar.
http://meta.wikimedia.org/wiki/Eliminating_index.php_from_the_url 

#LocalSettings.php
$wgScriptPath       = "";
## If using PHP as a CGI module, the ?title= style usually must be used.
$wgArticlePath      = "/$1";

Zusätzlich muss noch mod_rewrite aktiviert werden. Leider funktioniert die Regeln nicht in der .htaccess, deshalb müssen diese in die Apache-Conf 

#/etc/apache2/sites-enabled/mysite.de
RewriteEngine on

#forward old wiki-url to new one
RewriteRule ^/wiki/(.*)$        http://crazylinux.de/$1 [R=301,L]

# forbid bots to spider pages with certain urls that are forbidden in robots.txt anyway.

RewriteRule ^/index.php?.*$ /Hauptseite [L,QSA,gone]

No Anonymous

#LocalSettings.php
# Permission keys given to users in each group.
# All users are implicitly in the '*' group including anonymous visitors;
# logged-in users are all implicitly in the 'user' group. These will be
# combined with the permissions of all groups that a given user is listed
# in in the user_groups table.
#
# This replaces wgWhitelistAccount and wgWhitelistEdit
#
# The following line should be commented, otherwise these settings will
# throw away the settings on DefaultSettings.php (you probably don't want this).
# With this line commented you will only overwrite the settings you explicitly
# define here (that's what you probably want).
#$wgGroupPermissions = array();
$wgGroupPermissions['*'    ]['createaccount']   = false;
$wgGroupPermissions['*'    ]['read']            = true;
$wgGroupPermissions['*'    ]['edit']            = false;

Desweiteren sollten natürlich die 'Actions' ausgeblendet werden: http://www.mediawiki.org/wiki/Manual:FAQ#How_do_I_remove_the_article.2Fedit_etc_tabs_for_users_who_are_not_logged_in.3F

How do I add more buttons on the edit page?

For adding more toolbar buttons above the edit field, you can use JavaScript code to register them in your MediaWiki:common.js. For example, a button for source code: 

var customizeToolbar = function() {
        /* Your code goes here */
$('#wpTextbox1').wikiEditor('addToToolbar', {
                section: 'advanced',
                group: 'format',
                tools: {
                        buttonId: {
                                label: 'Highlight SourceCode',
                                type: 'button',
                                icon: '/skins/common/images/button_image.png',
                                action: {
                                        type: 'encapsulate',
                                        options: {
                                                pre: "<source lang=\"php\">",
                                                peri: "<?php\n\n?>",
                                                post: "

" 

                                       }
                               }
                       }
               }

}); };

/* Check if view is in edit mode and that the required modules are available. Then, customize the toolbar . . . */ if ( $.inArray( mw.config.get( 'wgAction' ), ['edit', 'submit'] ) !== -1 ) { 

       mw.loader.using( 'user.options', function () {
               if ( mw.user.options.get('usebetatoolbar') ) {
                       mw.loader.using( 'ext.wikiEditor.toolbar', function () {
                               $(document).ready( customizeToolbar );
                       } );
               }
       }

);}

Extensions

Auth_RemoteUser

Automatic REMOTE_USER Authentication extension automatically logs users using the REMOTE_USER environment variable. Probably you have to replace REMOTE_USER with PHP_AUTH_USER!

apache.conf 

<Location ~ "Spezial:Anmelden">
                #Turn on IMAP Authentication                        
                Auth_IMAP_Enabled on                                
                AuthUserFile /dev/null                              

                #AllowOverride none
                AuthBasicAuthoritative off
                AuthType Basic            
                AuthName Wiki-Login              
                Auth_IMAP_Authoritative on

                #Set the IMAP Server to which you want to connect (default=localhost):
                Auth_IMAP_Server localhost

                #Set the port on which the imap server is running (default=143):
                Auth_IMAP_Port 143

                #Turn on some extra logging (login attempts, etc.) in Apache's Error Log
                Auth_IMAP_Log off

Extension:SelectCategory

The SelectCategory extension provides three functions:

  • It shows a list of all categories (unless a custom root category is configured) in their hierarchical structure on the edit page.
  • It strips all categories linked within a page upon editing and selects them in the category list list.
  • It adds selected categories from the list to the text body of the page on saving.

Syntax-Highlighting

This extension adds the source tag to present formatted source code.

Last Updates (News)

http://www.mediawiki.org/wiki/Extension:News

broken with 1.12.0, but quick&dirty patch is available. It will use the old Parser-Class. Line $html="<fieldset..."; is optional. 

/www/htdocs/wiki/extensions/News$ diff NewsRenderer.php.orig NewsRenderer.php



86a87
>               $parser = new Parser_oldPP;

<                       $text .= $this->postfix;
<                       $html = $this->templateparser->recursiveTagParse( $text );

550a555
>                       $this->templateparser->mOptions = $this->templateoptions;

to apply the patch save the diff as NewsRenderer.php.patch and execute 

patch NewsRenderer.php <NewsRenderer.php.patch

<fixed>1 of 5 patches will not apply (don't know the reason), so you have to edit NewsRenderer.php manually. See line 337</fixed>

TagCloud

This module is intended to provide a tag cloud control for mediawiki. Each tag represents a mediawiki category, the size of the tag being determined by the number of articles on that category.
http://www.orangedino.org/index.php?name=News&file=article&sid=1
Download the zip archive and unarchive it. Copy the "tag_cloud.php" file to the "extension" folder in your wiki. 

#LocalSettings.php
require_once("extensions/tag_cloud.php");

Define the pages where you are going to add the tag cloud:
Edit the wiki page "MediaWiki:Tagcloudpages". Put one this page all the pages where you have included your tag, one page per line. 

Hauptseite

Add the CSS:
You should include this code into your "MediaWiki:Common.css" to get the default styles. After that you can freely tweak it: 

.tagcloud {
width: 98%;
text-align: center;
background-color: #FDFDFD;
border: 1px solid #EEEEEE;
padding: 15px 10px 15px 10px;
}
.tagcloud a {
color: #0052CB;
margin-left: 10px;
margin-right: 10px;
font-weight: bold;
}

Usage:
The simple way to display the cloud is to add in a page : 

<tagcloud>
</tagcloud>

Sitemap (Google)

http://www.mediawiki.org/wiki/Extension:Google_Sitemap

Note: Since MediaWiki 1.6, the MediaWiki core has a Google site map generator which may be more appropriate than this extension. It is a command-line utility, and it is located at maintenance/generateSitemap.php in your MediaWiki directory. The command line is "php generatesitemap.php sitename" and is run from the maintenance directory at the server's command line interface.

Top10-Pages
