Nginx rules for subdomain multisite install (Bedrock)

Question

I'm trying to move an existing Bedrock based multisite instance to nginx and am having difficulty getting a set of nginx rules to mimic the original .htaccess. Bedrock places the crux of the files in a wp/ subdirectory, but the urls still need to be accessible from the root domain.

The .htaccess is here as follows:

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) wp/$1 [L]
RewriteRule ^(.*\.php)$ wp/$1 [L]
RewriteRule . index.php [L]

I need these at least as nginx conf rules or preferably nginx vhost rules.

Answer 1

Ok some wise guy deleted my last post.

The answer, which the above member (@etc) gave to me on another forum, and is working quite fine, is as follows:

# Rewrites for Bedrock Multi-Site Subdomain Setup
rewrite /wp-admin$ $scheme://$host$uri/ last;
rewrite ^/(wp-.*.php)$ /wp/$1 last;
rewrite ^/(wp-(content|admin|includes).*) /wp/$1 last;

He revised his answer but did not post it back here. I simply wanted to update it as I ran across this thread as well.

Answer 2

rewrite /wp-admin$ $scheme://$host$uri/ last;
rewrite ^/(wp-.*.php)$ /wp/$1 last;
rewrite ^/(wp-(content|admin|includes).*) /wp/$1 last;

These are the equivalent rewrite rules that you need. Note, when you use this rewrite, you no longer have to set the site_url as /wp

I need to finish up some testing but will update here with the results.
