RoR Application and nginx with Passenger on Ubuntu

Question

i installed Ruby using RVM on a Ubuntu 13.10 Server. The same thing i do with rubygems and Rails. When i start my application with

rails server

and enter

localhost:3000

in my Browser it works.

Now i want to make the application visible for other users. So i checked rubyonrails.org/deploy-Site and decided to install nginx with Passenger.

gem install passenger
rvmsudo passenger-install-nginx-module

After this i downloaded stuff who was missing and do

rvmsudo passenger-install-nginx-module

again.

Before i runned

sudo service nginx start

i edit my .conf-File in /opt/nginx/conf/nginx.conf

server { 
listen 80; 
server_name example.com; 
passenger_enabled on; 
root /var/www/my_awesome_rails_app/public; 
}

As server name i take the ip-Adress for the domain. The passenger_enabled Line i added and as root i take /home/ServerName/AppName/public

My Problem is that i doesn't see anything when i open the server-ip-page.

When i run 'top' i see that nginx is running. The Ruby on Rails Application is also running.

AND i restartet nginx after editing the .conf-File.

Anybody know i solution OR how i can test nginx?

Thanks

Update - ps aux | egrep '(PID|nginx)'

Answer 1

Now its running.

Port 80 was blocked by the firewall of our university.

After unlocking Port 80 we get the nginx page when running the ip-adress of the server.

Finally we just needed to change the .conf of nginx with the following lines:

location / {
    proxy_pass http://localhost:3000/;
    proxy_redirect off;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_set_header X-NginX-Proxy true;
}

Source: Link

This part is important if you don't want access your Application with ip-adress:3000

The old location-part can be deleted.

Now you can restart/reload the nginx:

sudo service nginx restart

and start the rails server (on Port 3000 - default):

rails server

If you want you can start the rails server i another mode with:

rails server -e ....

Now you can access your RoR-Application.

Good Luck :-)
