Question

I try to deploy my rails app with Nginx, passenger on Ubuntu 12.04 x32. after all things is done, I visit my rails app, but it tell me 'We're sorry, but something went wrong.'.

then I cat /var/log/nginx/error.log, I find this lines:

update: my /etc/nginx/nginx.conf and /etc/nginx/sites-enabled/blog.conf: https://gist.github.com/wall2flower/b3f410317585a8803a27 https://gist.github.com/wall2flower/72316e8b437d654e7070

Answer 1

You sure have some PATH issues. Inside the /etc/nginx/nginx.conf, for passenger, you should be pointing to the ruby version where bundler is installed.

passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
passenger_ruby /home/thomas/.rvm/wrappers/default/ruby;

You can check this with the command

$ which ruby

The output of that command should be the one you should enter for passenger_ruby

If you haven't installed bundler yet go ahead and run gem install bundler

Also make sure that you are setting the environment variable in your server block:

server {
  listen 80 default;
  server_name blog.wall2flower.me;
  root /var/www/blog/current/public;
  passenger_enabled on;
}
