=File Uploading=

To upload files, allowed extensions must be specified in <code>LocalSettings.php</code>, and permission must be given for the web server (i.e., MediaWiki) to create arbitrary directories to store uploaded files.

===Step 1: Modify LocalSettings.php===

Add the following lines to LocalSettings.php to allow uploads of specific extensions:

<pre>
$wgFileExtensions = array('png','gif','jpg','jpeg','doc','xls','mpp','pdf','ppt','tiff','bmp','docx', 'xlsx', 'pptx','ps','odt','ods','odp','odg');
</pre>

or this, to allow uploads of any extensions:

<pre>
$wgStrictFileExtensions = false;
</pre>

===Step 2: Give Web Server Permissions===

Uploaded files go to <code>/www/w/images</code>, so give the webserver (user/group www-data using Ubuntu's defaults) read/write/execute access to images:

<pre>
sudo chown www-data:www-data images/
</pre>

and permissions should be 755 <code>rwxr-xr-x</code>:

<pre>
drwxr-xr-x 5 www-data www-data images/
</pre>

=URL Rewriting=

See this page for details: http://www.mediawiki.org/wiki/Manual:Short_URL/Apache

Getting urls like <code>ethane.siluria.com/wiki/PageName</code> working requires several steps:

===Step 1: Modify LocalSettings.php===

Near the top of LocalSettings.php, the variable <code>$wgScriptPath</code> is defined. Redefine it, along with the <code>$wgArticlePath</code> and <code>$wgUsePathInfo</code> variables:

<pre>
###############################################
#
$wgScriptPath = "/w";
$wgArticlePath="/wiki/$1";
$wgUsePathInfo = true;
#
###############################################
</pre>

which will properly reformat requests from <code>/wiki/$1</code> to MediaWiki.

===Step 2: Modify Apache Configuration File===

Modify the Apache configuration file for a wiki VirtualHost as follows:

<pre>

Alias /wiki /www/w/index.php
Alias /w /www/w
<Directory "/www/w">
# Enable the rewrite engine
RewriteEngine On
# Short url for wiki pages
RewriteRule ^/?wiki(/.*)?$ %{DOCUMENT_ROOT}/w/index.php [L]

Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>

</pre>
