Details

It will not import or "register" images (even if they are in upload directory and there are articles referencing them). You should use the or  scripts to do this.

Using the script
This script must be run from the command line.

Open a terminal or command window and change directories to the maintenance subdirectory of the wiki.

Example
 vi-notebook:/var/lib/mediawiki1.7# cat AdminSettings.php  # Create this file if not exist 

vi-notebook:/var/lib/mediawiki1.7# php maintenance/rebuildall.php Dropping index... Rebuilding index fields for 1426 pages... 1000 Rebuild the index...
 * Rebuilding fulltext search index (if you abort this will break searching; run this script again to fix):

Loading from page and revision tables... Updating links...
 * Rebuilding recentchanges table:

Refreshing link table. Starting from page_id 1 of 1426. 100 200 300 400 500 600 700 800 900 1000 1100 1200 1300 1400 Done.
 * Rebuilding links tables -- this can take a long time. It should be safe to abort via ctrl+C if you get bored.
