Correct.

Ok, so long as your idea of "load the requested uri" matches nginx's.

According to http://nginx.org/r/try_files, that should probably try to
send you the content of /usr/local/nginx/html/wordpress/index.php or 404.

What does

  curl -v http://whatever/wordpress/

show?

Is your blank page a http 200 with no content, or a http 200 with some
content that the browser shows as blank, or some other http response?

try_files probably doesn't do what you think it does.

The final argument does an internal rewrite. The other arguments are
served as files in the current context, unless they end in "/" in which
case the "index" value is involved.

  curl -v http://whatever/wp-admin/

The logs will show which location is used. Can you see which
file-on-the-filesystem wp-admin.php is returned?

(I don't see anything in your provided config which would associate
wp-admin.php with a request for /wp-admin/. I would have expected the
file /usr/local/nginx/html/wordpress/wp-admin/index.php to be returned.)

The initial request will have a "location" chosen.

A subrequest will have a "location" chosen.

"just serve this file" will not have a "location" chosen.

For info: those two lines probably don't do anything useful here.

Not unless there's a request or subrequest that best-matches this
location.

Good luck with it,
