How to Setup an I-Name-Enabled Mediawiki

From I-names Development Wiki

Perform the following steps to iname-enable version 1.8 of Mediawiki. Please feel free to add any missing information or provide questions to the Tech FAQs page.

1. Download Mediawiki from http://www.mediawiki.org/wiki/Download.

2. Follow the Mediawiki instructions for uploading and installing Mediawiki, as required.

3. Download the OpenID extension located at http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/OpenID/ into the extensions/OpenID directory of your MediaWiki installation. There is a README file that explains the installation steps.

4. Download the PHP OpenId library from http://www.openidenabled.com/openid/libraries/php. Upload as required.

5. Edit LocalSettings.php, as required.

• Note that for this wiki, LocalSettings.php was edited as follows:

# To prevent anonymous users from editing
$wgGroupPermissions['*']['edit'] = false;

# To change the default login/create account screen with the OpenId prompt.
$wgSpecialPages['Userlogin'] = array('SpecialPage', 'OpenIDLogin');


require_once("$IP/extensions/OpenID/OpenID.php");
$wgOpenIDConsumerDenyByDefault = false;
$wgTrustRoot = 'http://dev.inames.net/wiki/index.php';
$wgOpenIDConsumerStoreType = 'file';
$wgOpenIDServerStoreType = 'file';
$wgOpenIDConsumerStorePath = '/tmp/openid-consumer';
$wgOpenIDServerStorePath = '/tmp/openid-server';

6. Apply the following patch if you configure your mySql database with a prefix.

diff -crN temp/Consumer.php temp2/Consumer.php
*** temp/Consumer.php	2006-12-28 16:15:50.000000000 -0800
--- temp2/Consumer.php	2006-12-28 16:16:07.000000000 -0800
