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:

have someone experienced same problem? thanks

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;
}

Answer 2

You need to genarate binstubs to fix the problem:

bundle install --binstubs

Answer 3

try:

bundle exec passenger start ...

Answer 4

As karlingen notes, the issue is the result of PATH issues, however if you are using RVM, you will want to get your path to the correct ruby another way...

Best thing is to follow Passenger's own guide for finding this info:
