I'm a Nginx novice, but I have it set up with Wordpress Multisite (subdirectories) and php-fpm, and it's working great as is. This lets me set up Wordpress sites off the web root:
domain.com/site1 - a Wordpress network single site, which renders as expected.
domain.com/site2 - ditto
etc.
Concurrently, I can easily create static files in the web root that don't conflict or interact with Wordpress, and they are also rendered normally.
domain.com/hello.html - rendered normally
domain.com/hello.php - rendered normally, including php processing
domain.com/static/hello.php - rendered normally (along as "static" isn't a WP single site name)
What I'd like to do, and this is where I'm out of my depth with nginx.conf, is create a root directory
domain.com/static
and put static sites in there
domain.com/static/site3
domain.com/static/site4
and have Nginx check the request that comes into the root
request comes in for: domain.com/site3
and before handing off to Wordpress, check to see if it exists in the /static folder
checks: domain.com/static/site3 - static content exists there
and if so, serves that content while maintaining the root URI.
serves: domain.com/site3 (with content from domain.com/static/site3)
if not, it lets Wordpress check if /site3 is a Wordpress single network site as it does now, and the process continues normally.
In nginx.conf, in the server section, I start with this try_files rule:
location / {
try_files $uri $uri/ /index.php?q=$uri&$args;
}
I then include a bunch of Wordpress specific rules as identified at http://codex.wordpress.org/Nginx under the subdirectory section.
I can see that rewrite rules might take care of it easily, but in my experimentation I've only achieved a bunch of looping (/static/static/static, etc.) and managed to bypass Wordpress if the looping stopped. Sorry if this is a very long-winded way of asking a simple question, but I'm definitely learning some of this stuff for the first time.
Thanks!
