Updating nginx config while attempting to invert directory structure - laravel

Question

I am trying to flip the directory structure of a PHP app that contains a Laravel sub-app that currently has the following directory structure:
/-
/directory1-
script1.php
/laravel-
/public-
/css-
some-file.css
... other laravel files ...
What I'm trying to do is now flip the "legacy" code in the parent directory into the Laravel application so that the directory structure now looks like this:
/-
/legacy-
/directory1-
script1.php
/public-
/css-
some-file.css
... other laravel files ...
I'm running into difficulty with the nginx configuration, I am able to successfully run the /legacy scripts and load the static public files in Laravel (such as some-file.css above), but none of my Laravel routes are working correctly. This is complicated by the fact that I don't want any of the legacy paths to change (I still want / to go to the now /legacy/index.php) and I want the Laravel app to be prefixed by /laravel (since I have front-end code calling an API at /laravel/api/v1 that I don't want to update just yet).
Here's what I have for the nginx config for the two different locations:
server {
# ...
root /var/www/legacy;
index index.php index.html index.htm;
location ~ \.php$ {
fastcgi_pass php-upstream;
fastcgi_index index.php;
fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location / {
try_files $uri $uri/ $uri.html $uri.php?$query_string;
}
location /laravel {
fastcgi_index index.php;
include fastcgi_params;
rewrite ^/laravel/public/(.*) /../public/$1;
try_files $uri /../public/index.php?$query_string;
}
}
The error I am getting from nginx is: FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, which I think is talking about the SCRIPT_FILENAME FastCGI param. I tried adding a named location for this, similar to the approach in this answer:
location / {
try_files $uri $uri/ $uri.html $uri.php?$query_string #laravel;
}
location #laravel {
fastcgi_pass php-upstream;
fastcgi_index index.php;
fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;
fastcgi_param SCRIPT_FILENAME /var/www/public/index.php?$query_string;
include fastcgi_params;
}
But this has the same effect. If someone has a solution that will be able to route requests from both /laravel/api/v1/.* and /api/v1/.* to the Laravel app that would also be appreciated.

Assuming the parent directory is www, I think the below config (from this post) will work:
server {
# ...
root /var/www/legacy;
index index.php index.html index.htm;
location / {
try_files $uri $uri/ $uri.html $uri.php?$query_string;
}
location /laravel {
alias /var/www/public;
try_files $uri $uri/ #laravel;
location ~ \.php {
fastcgi_index index.php;
fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $request_filename;
fastcgi_pass php-upstream;
}
}
location #laravel {
rewrite /laravel/(.*)$ /laravel/index.php?/$1 last;
}
location ~ \.php$ {
fastcgi_index index.php;
fastcgi_buffers 16 16k;
fastcgi_buffer_size 32k;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_pass php-upstream;
}
}
To deal with duplicate fastcgi_* declarations, you can either declare them in the server block or copy them in a file and include it, this article explains how inheritance in Nginx works.
