Ruby on Rails, nginx, passenger on production server (cannot load such file — rubygems/path_support)

Question

I installed:

• Centos 6
• Ruby 1.9.3-rc1
• Passenger gem and passenger nginx module ( compiled against own source 1.1.6)
• Installed rails 3

Answer 1

In my case, I also met this problem:
( My environment: Centos 5.8, rbenv 1.9.3p327, passenger 3.0.19, nginx( compiled and installed by passenger) . I googled around but didn't find any direct answer ( keyword: rbenv, passenger, cannot load such file -- rubygems/path_support), so I write my solution here.

I have checked and set nginx user to root, not works. and changed all the privileges of gem folder to 777. not works.

finally I got the solution: add these 2 lines of code to your Nginx config file:

passenger_default_user root;
passenger_default_group root;

so now your nginx config file looks like:

# /opt/nginx/config/nginx.conf
user  root;  # seems this line of code doesn't take effect.
http {
  passenger_root /root/.rbenv/versions/1.9.3-p327/lib/ruby/gems/1.9.1/gems/passenger-3.0.19;
  passenger_ruby /root/.rbenv/versions/1.9.3-p327/bin/ruby;

  # these lines are the key!!!
  passenger_default_user root;
  passenger_default_group root;

  server {
    listen 80;
    root ;
    passenger_enabled on;
  }
}
