 $wgScriptPath = "/w";         # Path to the actual files (right part of first rewrite rule). Should already be there
 $wgArticlePath = "/wiki/$1";  # Virtual path (left part of first rewrite rule). MUST be DIFFERENT from the path above!
 $wgUsePathInfo = true;

-and the following lines as well.

 ## This is added by Kevin. {
 # to restrict anonymous users from editing any page: set it false.
 $wgGroupPermissions['*']['edit'] = false;
 
 # to restrict anonymous users from reading any page: set it false.
 # $wgGroupPermissions['*']['read'] = false;
 
 # to I restrict account creation: set it false.
 $wgGroupPermissions['*']['createaccount'] = false;
 
 $wgGroupPermissions['*']['createpage']       = false;
 $wgGroupPermissions['*']['createtalk']       = false;
 $wgGroupPermissions['*']['writeapi']         = false;
 
 $wgAllowUserJs  = true;
 $wgAllowUserCss  = true;
 
 require_once("extensions/SyntaxHighlight_GeSHi/SyntaxHighlight_GeSHi.php");
 
 $wgAjaxSearch   =       true;
 # $wgVariantArticlePath =       true;
 # $wgRedirectSources            =       true;

-Then create wiki.conf file in the /etc/apache2/conf.d directory and add.

# /var/www/w should be the directory where the wiki is installed.
Alias /wiki /var/www/w/index.php 

-the following lines are optional

<Directory /var/www/w/>
        Options +FollowSymLinks
        AllowOverride All
        order allow,deny
        allow from all
</Directory>

# AllowOverride All is to use .htaccess file if the default setup of it is disabled (AllowOverride None).
