Short url of Mediawiki

When I changed my domain name, I planed three subdomains for the future usage: www, blogs and wiki, while unfortunately at that time only the blogs.dbcloudsvc.com had some contents and in fact it was migrated from previous www.lunixdb.com.

Now I have installed the Mediawiki and the wiki.dbcloudsvc.com is online, so the first thing I want to do is about the permanent link, or short url in Mediawiki world.

Need the following two steps:

1. Update the file LocalSettings.php
   [root@www wiki]# diff LocalSettings.php*
   29,30d28
   < $wgArticlePath = "/$1";
   < $wgUsePathInfo = true;
   [root@www wiki]# ls LocalSettings.php*
   LocalSettings.php  LocalSettings.php.bak

2. Add the rewrite rule for Mediawiki in the nginx configuration file
   # MediaWiki Rewrite
   if ($host = wiki.dbcloudsvc.com) {
   set $nrw W;
   }
   if (!-e $request_filename) {
   set $nrw "${nrw}Y";
   }
   if ($nrw = WY) {
   rewrite ^/([^?]*)(?:\?(.*))? /index.php?title=$1&$2 last;
   }

For me, www and wiki subdomains share the same configuration file, so I have to check which one is accessed.

And I began to write my first installation page on the wiki.
