You can have clean URLs with the one-click install of Mediawiki. Here’s how.
Modify the following in LocalSettings.php after you have set it up:
$wgArticlePath = "/wiki/$1";
In the ROOT directory of www.yourdomain.com, place the following .htaccess file:
uncomment this rule if you want Apache to redirect from www.mysite.com/ to www.mysite.com/wiki/Main_Page
RewriteRule ^/$ /wiki/Main_Page [R]
do the rewrite
RewriteRule ^wiki/?(.*)$ /w/index.php?title=$1 [L,QSA]
[/code]Note that I haven’t tested the redirect RewriteRule, as I use an index.php in my root directory that sends a Location header, so I can more easily take the site down for maintenance.
