I made the conversion from apache2 to nginx+php-fpm and got Wordpress to work.

The last piece of the puzzle is WP Super Cache. Somehow it only does the super cache thing for homepage not individual pages.

http://domain.com/ works but
http://domain.com/2001/02/my-blog-post/ doesn't work.

Any idea what may be wrong?

It is amazing people (including me) copy config from internet without understanding it completely.

After rewriting the rewrite rules now it is working beautifully.
