Question

Can NOT run rails application on my server's IP address only runs at localhost:3000

Posted July 28, 2017 16.9k views
Ruby on RailsNginxRubyUbuntu 16.04

I deployed my rails application on the server with capistrano, nginx and puma, following this tutorial-
https://www.digitalocean.com/community/tutorials/deploying-a-rails-app-on-ubuntu-14-04-with-capistrano-nginx-and-puma.

App is running fine in localhost:3000.
I can also run on-> rails server –binding=MyIP
I can see my app in action on-> http://MyIP:3000

When I browse http://My_IP , I saw welcome to nginx screen.
But according to document, when I run -
sudo rm /etc/nginx/sites-enabled/default
sudo ln -nfs “/home/username/apps/appname/current/config/nginx.conf” “/etc/nginx/sites-enabled/appname”
(Ofcourse I changed username and appname)

I can NOT connect to my server’s IP address (says Unable to connect.. can’t establish a connection).

Nginx server is running. I also tried running with systemctl start nginx command.

May be something wrong with Puma? I can NOT connect my Puma web server to the Nginx reverse proxy? I am not sure.

I searched online, some people have puma.rb file but I don’t have(document does not mention). I just have Puma gem in my Gemfile. Do I need config/puma.rb file?

I have-
Rails -v 4.2.5
Ruby -v 2.3.0

So my problem is I can NOT run my application on my servers IP address. App is only running default on localhost:3000
Is it problem with port 80? Puma is not connected to port 80?

I need help running my application in production.

Thank you.

Hi @vishdev

Without seeing the content of the Nginx site configuration that you link to, then it’s difficult to know what’s going on. So post this file:

/home/username/apps/appname/current/config/nginx.conf

And also post the last 10 lines from your Nginx error log:

tail -10 /var/log/nginx/error.log

Hi Hansen,
Thank you for your reply.
Here is my nginx.conf file-

upstream puma {
  server unix:///home/vish/apps/globe3/shared/tmp/sockets/globe3-puma.sock;
}

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

  root /home/vish/apps/globe3/current/public;
  access_log /home/vish/apps/globe3/current/log/nginx.access.log;
  error_log /home/vish/apps/globe3/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;
}

sudo tail -10 /var/log/nginx/error.log

    @vishdev

    Okay, in the Nginx configuration change this:

      listen 80 default_server deferred;
  # server_name example.com;

    To this to make that site available on anything (your IP, a domain):

      listen 80 default_server;
  server_name _;

    Then you need to make sure that Puma is running and using the same socket as you have defined in Nginx:

    /home/vish/apps/globe3/shared/tmp/sockets/globe3-puma.sock

    And then test your Nginx configuration and restart it:

    sudo service nginx configtest
sudo service nginx restart
