Nginx+Passenger serving assets on sub uri

Question

I'm serving a Rails application under a sub-uri like https://projects.mydomain.com/app1/

But my assets are not loading.

here is my nginx config :

location ~ ^/app1(/.*|$) {
    root /srv/www/app1/current/public;

    passenger_base_uri /app1;
    passenger_app_root /srv/www/app1/current;
    passenger_document_root /srv/www/app1/current/public;
    passenger_enabled on;
}

  location ~ ^/(assets)/ {
    root /srv/www/app1/current/public;
    gzip_static on;
    expires max;
    add_header Cache-Control public;
}

The application is loaded, with all URL/PATHes prefixed for /app1/ but the assets are not loaded.

https://projects.mydomain.com/app1/assets/application-123456.css Does NOT work

When I try the assets path without prefix, i can see the assets exists:

https://projects.mydomain.com/assets/application-123456.css DO work

Any idea ?

UPDATE:

Added error_log /var/log/nginx/error.log debug; Of course this is an edited extract:

As a additionnal information, when in this nginx location directive I try to replace the root directive by an alias one I get a 403.

  location ~ ^/app1/assets {
    alias /srv/www/app1/current/public/assets;
    #root /srv/www/app1/current/public;
    gzip_static on; # to serve pre-gzipped version
    expires max;
    add_header Cache-Control public;
    passenger_enabled on;
  }

I tried regexp like ^/app1/assets/.* but still not working. (403 forbidden for the alias)

UPDATE2:

2015/12/18 15:38:49 [debug] 878#0: *1 open index "/srv/www/app1/current/public/assets/application-123456.css/index.html"

Tried to add an index directive, not working (404).
Tried to add a try_files, still have a /index.html added at the end, therefore having same 404.

Did you try location `/app1/assets/`? If so, please enable the debug error log and show it for an asset request. — gxx, Dec 17 '15 at 21:52
Hi, yes I tried that, and also directives like alias and intern, different regexp using /app1/assets, etc. Nothing do. I'll add a UPDATE section with the debug log. — gdurelle, Dec 18 '15 at 10:19

Got a friend's help. Here is how to works:

server {
  listen *:80;
  listen [::]:80;
  server_name projects.mydomain.com;
  server_tokens off;
  return 301 https://$server_name$request_uri;
}

server{
  listen 0.0.0.0:443 ssl;
  listen [::]:443;
  server_name projects.gdurelle.com;
  server_tokens off;

  location ~ ^/app1(/.*|$) {
    alias /srv/www/app1current/public$1;

    passenger_base_uri /app1;
    passenger_app_root /srv/www/app1/current;
    passenger_document_root /srv/www/app1/current/public;
    passenger_enabled on;
  }

  location ~ ^/app2(/.*|$) {
    alias /srv/www/app2/current/public$1;

    passenger_base_uri /app2;
    passenger_app_root /srv/www/app2/current;
    passenger_document_root /srv/www/app2/current/public;
    passenger_enabled on;
  }
}

The first location seems to have a typo `alias /srv/www/app1current/public$1;` should be `alias /srv/www/app1/current/public$1;` — pauljohn32, Jan 28 '20 at 19:04
