Just wanted to help out my fellow slicers who are running nginx+fcgi+php+wordpress. I wanted to get some pretty permalinks using /%category%/%postname%/.
Here's the config snippet:

location / {
root /var/www/directory; <--- change this to your directory
index index.php;
rewrite ^/(.+)/(.+)/$ /?category=$1&name=$2;
if ($request_uri != '/wp-admin/') {
rewrite ^/(.+)/$ /?pagename=$1;
}
}

I don't have any use for archives so I didn't put them in my conf file. This is something just to get you started. The first rewrite takes whatever is in between / and puts them into a query string format. The second rewrite is for pages with the exception of wp-admin so you can still login to your control panel. I haven't tested downloading files but everything else including the admin section seems to work.

Here's a great reference I stumbled across if you're going to make your own query strings:

Okay I finally got it. Sorry for the rough first drafts here it is:

if ($http_user_agent !~ FeedBurner) {
rewrite ^/feed/$ http://feeds.feedburner.com/yourFeed permanent; <----change this
}
if ($http_user_agent !~ FeedBurner) {
rewrite ^/comments/feed/$ http://feeds.feedburner.com/yourFeedComments permanent; <--- change this
}
if (!-e $request_filename) {
rewrite ^/([^.]*[^/])$ http://yoursite.com/$1/ last; <---change this
rewrite ^/wp-admin/$ /wp-admin/ break;
rewrite ^/category/(.+)/$ /?category$1 break;
rewrite ^/(.+)/(.+)/$ /?category=$1&name=$2;
rewrite ^/(.+)/$ /?pagename=$1;
}

Okay the first two if only affect feed urls. The second set check for wp-admin and category and also if trailing slash is not set (thanks fucoder.com).

Now you tell me....lol

Thanks scotty.

I know it’s been a while, but how would I use this concept to enable configuration level redirecting to feedburner for any number of domains being served through the virtual host container?

TIA!
