Basic Installation

Follow the instructions at [1]

Bring mediawiki-1.5.7.tar.gz from [2] and unpack it into katlas:/www/html/drorbn. In that directory:

chown -R root:apache *
chmod -R o-rwx *
chmod -R g+rw config
chmod -R g+rw images

Go to [3] to set up the wiki:

 Sysop account: drorbn
 Name of SQL database: drorbn
 DB account: drorbn
 Database table prefix: drorbn_

Move config/LocalSettings.php file into the parent directory.

Go visit the wiki.

Add lines to backup script:

 mysqldump -u drorbn -p*** drorbn > drorbn-backup.sql
 gzip -9 -f drorbn-backup.sql
 cp -f drorbn.sql.gz /www/html/backups

Allow logins on several wikis on the same server: Add the following line to LocalSettings.php after $wgSiteName = ...:

ini_set("", "{$wgSitename}Session" );

See documentation on customizing the interface and the User's Guide for usage and configuration help.

Modifying the navigation box

Edit MediaWiki:Sidebar.

Enable <math></math> processing

First, make the /images directory writable:

chmod -R g+rw images

Next, go to the math directory under the wiki installation, and run make. Finally, edit LocalSettings.php to enable TeX.

Finally, I've enabled \bigcirc and dbnsymb as explained at

Enable image uploads

In LocalSettings.php, uncomment out $wgEnableUploads = true; and add

$wgFileExtensions = array( 'png','jpg','jpeg','ogg','pdf');

Allow us to be framed

Comment out the obvious line in skins/common/wikibits.js.

Spam Protection

Preventing edits that contain 3 or more "http:" string in one line: Add to LocalSettings.php:

$wgSpamRegex="/htp:.*htp:.*htp:|overflow: *auto;|display: *none;/";

(though replace htp's by http's).

Block anonymous edits and account creations

In LocalSettings.php, add

# Prevent new user registrations except by sysops
$wgGroupPermissions['*']['createaccount'] = false;
# Disable anonymous editing
$wgGroupPermissions['*']['edit'] = false;

and then edit MediaWiki:Emailforlost. (see Mediawiki's Manual: Preventing Access.)
