Rails project located at port 8080 while nginx at port 80

Question

I have deployed my Rails app to VPS (DigitalOcean). I have installed NGINX that will handle all my static css, js and html files.

I have uploaded my project via capistrano.

When I open my page at example.com it shows me page Welcome to NGINX. I can only access to my pages by entering example.com:8080/admin and it does not load css, js and html files.

NGINX does not detect static files, which are generated by Rails.

What did I miss? Why I my rails app is on 8080 port?

My nginx.conf file is:

upstream puma {
  server unix:///var/www/newsapp/shared/tmp/sockets/newsapp-puma.sock;
}

server {
  listen 80 default_server deferred;
  # server_name example.com;

  root /var/www/newsapp/current/public;
  access_log /var/www/newsapp/current/log/nginx.access.log;
  error_log /var/www/newsapp/current/log/nginx.error.log info;

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

  try_files $uri/index.html $uri @puma;
     location @puma {
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_set_header Host $http_host;
     proxy_redirect off;

     proxy_pass http://puma;
  }

  error_page 500 502 503 504 /500.html;
  client_max_body_size 10M;
  keepalive_timeout 10;
}

I'm using Puma. My deploy.rb file:

set :application, 'newsapp'
set :repo_url, 'https://example@bitbucket.org/example.git'
set :linked_dirs, %w(
   bin log vendor/bundle public/system
   tmp/pids tmp/cache tmp/sockets
)
set :puma_bind, "unix:///var/www/newsapp/shared/tmp/sockets/newsapp-puma.sock"
set :puma_state,      "/var/www/newsapp/shared/tmp/pids/puma.state"
set :puma_pid,        "/var/www/newsapp/shared/tmp/pids/puma.pid"
set :puma_access_log, "/var/www/newsapp/shared/log/puma.error.log"
set :puma_error_log,  "/var/www/newsapp/shared/log/puma.access.log"

namespace :deploy do

   after :restart, :clear_cache do
     on roles(:web), in: :groups, limit: 3, wait: 10 do
     # Here we can do anything such as:
     # within release_path do
     #   execute :rake, 'cache:clear'
     # end
     end
   end

end

My config/deploy/production.rb:

server "my.server.ip.here",
   :user => "deployer",
   :roles => %w(web app db)

My nginx.conf file located on VPS /etc/nginx:

user www-data;
worker_processes 4;
pid /run/nginx.pid;

events {
    worker_connections 768;
    # multi_accept on;
}
http {
    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;

    gzip on;
    gzip_disable "msie6";

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

There are a lot of lines which were commented. I have just skipped them.

My var/log/nginx/error.log has that kind of lines:

 2015/07/12 13:25:08 [emerg] 12215#0: open() "/var/www/newsapp/newsapp/current/log/nginx.access.log" failed (2: No such file or directory)

You access to Puma via socket not by port. It seems you have multiple Nginx server blocks that shows it listens more than port 80. Please show whole Nginx config and make sure error_log is empty — Anatoly, Jul 13 '15 at 07:23
@mikhailov Well this is my `nginx.conf` fle that is in my Rails project. You mean config that is located in my VPS? — Mr.D, Jul 13 '15 at 07:32
server unix:///var/www/newsapp/shared/tmp/sockets/newsapp-puma.sock; is wrong...remove all extra forward slashes....and use /var/www/newsapp.... — Milind, Jul 13 '15 at 11:37

I think maybe you do not remove default page in site-enabled.

rm -f /etc/nginx/sites-enabled/default

Next, your nginx access log open failed problem.

Try changing your log file path.

access_log /var/www/newsapp/current/log/nginx.access.log;
  # => /var/www/newsapp/shared/log/ACCESS_LOG_FILENAME.log
error_log /var/www/newsapp/current/log/nginx.error.log info;
  # => /var/www/newsapp/shared/log/ERROR_LOG_FILENAME.log

Maybe I think when nginx have started first, there is no current folder because current folder is generated when app is deployed.
And nginx is not restarted whenever deploying your app. So try restarting nginx or modifying nginx log path to static path not symlink path. (Don't forget to restart nginx after modify conf file)

css, js not loading problem.

Did you execute assets:precompile while deploying ?
Check if there is require 'capistrano/rails' in Capfile.
and then set your :rails_env in deploy.rb.

and deploy again!

In my nginx.conf I have changed my upstream puma to:

upstream puma {
   server 0.0.0.0:8080;
}

In my config/deploy.rb I needed to write this:

set :puma_bind, "0.0.0.0:8080"
