How deploy ruby on rails application on nginx with Passanger

Question

I spent lot of hours and just stuck :(

1. Build app in ruby on rails
2. On dev environment working with Apache
3. Have to install production on Ubuntu 18.04 LTS with nginx and passenger
4. I add Passenger to nginx how it's described by Passenger Library here

App not working and logs showing:

1. 403 forbidden error for root ( https://cennik.leczymed.pl )

   2019/02/08 21:46:19 [error] 4743#4743: *2 directory index of "/var/www/html/cennik/public/" is forbidden, client: XXX.XXX.XXX.XXX, server: cennik.leczymed.pl, request: "GET / HTTP/2.0", host: "cennik.leczymed.pl"

2. 404 not found for others sublinks (ex. https://cennik.leczymed.pl/rtg )

   2019/02/08 21:46:25 [error] 4743#4743: *2 open() "/var/www/html/cennik/public/rtg" failed (2: No such file or directory), client: XXX.XXX.XXX.XXX, server: cennik.leczymed.pl, request: "GET /rtg HTTP/2.0", host: "cennik.leczymed.pl"

My configurations:

/etc/nginx/sites-available/cennik.conf

server {
    listen 80;
    server_name cennik.leczymed.pl;

    include snippets/letsencrypt.conf;
    return 301 https://cennik.leczymed.pl$request_uri;
}


server {
    listen 443 ssl http2;
    server_name cennik.leczymed.pl;

    # Tell Nginx and Passenger where your app's 'public' directory is
    root /var/www/html/cennik/public;

    # log files
    access_log /var/log/nginx/cennik.leczymed.pl.access.log;
    error_log /var/log/nginx/cennik.leczymed.pl.error.log;

    # Turn on Passenger
    passenger_enabled on;
    passenger_ruby /usr/bin/ruby2.5;

    ssl_certificate /etc/letsencrypt/live/cennik.leczymed.pl/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/cennik.leczymed.pl/privkey.pem;
    ssl_trusted_certificate /etc/letsencrypt/live/cennik.leczymed.pl/chain.pem;
    include snippets/letsencrypt.conf;
    include snippets/ssl.conf;

    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;

    location ^~ /assets/ {
     gzip_static on;
     expires max;
     add_header Cache-Control public;
    }

}

All files of application are in /var/www/html/cennik catalog.

All files and catalogs owner is cennik user (as described in recipe).

Catalog /public inside RoR app is with all privileges (chmod 777).

Any ideas guys ?

Update:

passenger-config --ruby-command

passenger-config was invoked through the following Ruby interpreter:
  Command: /usr/bin/ruby2.5
  Version: ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux-gnu]
  To use in Apache: PassengerRuby /usr/bin/ruby2.5
  To use in Nginx : passenger_ruby /usr/bin/ruby2.5
  To use with Standalone: /usr/bin/ruby2.5 /var/lib/gems/2.5.0/gems/passenger-6.0.1/bin/passenger start

The following Ruby interpreter was found first in $PATH:
  Command: /home/artur/.rbenv/shims/ruby
  Version: ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]
  To use in Apache: PassengerRuby /home/artur/.rbenv/shims/ruby
  To use in Nginx : passenger_ruby /home/artur/.rbenv/shims/ruby
  To use with Standalone: /home/artur/.rbenv/shims/ruby /var/lib/gems/2.5.0/gems/passenger-6.0.1/bin/passenger start

So, I think that nginx configuration cennik.conf declare correct place of catalog for ruby : /usr/bin/ruby2.5

Any other ideas how to solve it ?

************************ UPDATE *******************************

Ok. So I found few things which can help others. Problem as mine is only for Ubuntu upgraded to 18.04 from previous versions. Instalation of nginx is not overwrite confs for nginx (this can be solved manually). Bigger problem is that nginx package which is delivered for Ubuntu 18.04 is not compiled with passenger support. So I'm looking now for solution how to compile nginx with passenger module in it and still use it my systemctl functions - installation from sources work, but you can't work with it as a service :(

I found some special receipe for comapiling Ubuntu package with changes inside compilation process but any of my try to put correct add-on for passenger already fail.

Anybody can help me ?

I add Passenger to nginx how it's described by Passenger Library here

Looks like Passenger in not configured. As you're using RVM, you should have another location for ruby executable. To get ruby path, go to application root and run the following command and replace passenger_ruby directive.

> cd /var/www/html/cennik
> passenger-config --ruby-command
# It shows output like this

passenger-config was invoked through the following Ruby interpreter:
  Command: /home/deploy/.rvm/gems/ruby-2.3.5/wrappers/ruby
  Version: ruby 2.3.5p376 (2017-09-14 revision 59905) [x86_64-linux]
  To use in Apache: PassengerRuby /home/deploy/.rvm/gems/ruby-2.3.5/wrappers/ruby
  To use in Nginx : passenger_ruby /home/deploy/.rvm/gems/ruby-2.3.5/wrappers/ruby
  To use with Standalone: /home/deploy/.rvm/gems/ruby-2.3.5/wrappers/ruby /usr/bin/passenger start

Catalog /public inside RoR app is with all privileges (chmod 777).

Making public directory executable isn't good idea. It may contains files uploaded by users. Just set permissions to 755 and chown to user or group running nginx (www-data).
