How to make passenger and rvm work together? - ruby

Question

I've had rvm installed beforehand. And I decided to install passenger from a package (nginx-full and passenger) and would like to use the ruby installed with rvm. But somehow it doesn't work. Here's the test sinatra app I'm using (~yuri/a1/app.rb):
require 'rubygems'
require 'sinatra'
get '/' do
"Hello and Goodbye"
end
~yuri/a1/config.ru:
require 'rubygems'
require 'sinatra'
require './app.rb'
run Sinatra::Application
nginx.conf:
http {
...
passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
# the paths in the above file point out to debian repository's ruby version
server {
server_name a1;
root /home/yuri/a1;
access_log /var/log/nginx/a1-access.log;
error_log /var/log/nginx/a1-error.log;
passenger_enabled on;
passenger_ruby /home/yuri/.rvm/wrappers/ruby-1.9.3-p385#a1/ruby;
}
}
But when I do w3m http://a1 access.log says:
127.0.0.1 - - [12/Sep/2013:21:14:58 +0300] "GET / HTTP/1.0" 403 168 "-" "w3m/0.5.2+cvs-1.1027"
and error.log:
2013/09/12 21:14:58 [error] 27622#0: *1 directory index of "/home/yuri/tr/" is forbidden, client: 127.0.0.1, server: tr, request: "GET / HTTP/1.0", host: "a1"
The app works if I run it as follows: rvm ruby-1.9.3-p385#a1 && ruby app.rb.
Is there a way to track down what's happening there? Or how to make it work?

Answer 1

passenger expects application directories to have a certain layout. Particularly, config.ru must reside up one level relative to the document root. That is:
/etc/nignx/nginx.conf:
...
http {
...
passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
server {
server_name a1;
root /home/yuri/a1/public;
access_log /var/log/nginx/a1-access.log;
error_log /var/log/nginx/a1-error.log;
passenger_ruby /home/yuri/.rvm/wrappers/ruby-1.9.3-p385#a1/ruby;
passenger_enabled on;
}
}
~yuri/a1/app.rb:
require 'sinatra'
get '/' do
"Hello World!"
end
~yuri/a1/config.ru:
require './app'
run Sinatra::Application
And:
$ rvm install 1.9.3-p385
...
$ rvm --create use 1.9.3-p385#a1
...
$ curl http://a1
Hello World!

I just went through setting up passenger 4.0.17 on Ubuntu Precise using the apt approach.
Here is what worked for me.
In the /etc/nginx/nginx.conf
passenger_root /usr/lib/ruby/vendor_ruby/phusion_passenger/locations.ini;
passenger_ruby /usr/local/rvm/wrappers/ruby-2.0.0-p247/ruby;
Try moving the passenger_ruby to outside of the server block.
Good Luck
