Passenger not spawning application

[Steel Fu]

I'm trying to get a Rails 3 app up w/ Ruby 1.9.2-preview3 using RVM.
Host is running Ubuntu 10.04.

I keep getting this error in the logs and I'm not sure where to dig
for more details on whats going on:

[ pid=8505 file=ext/apache2/Hooks.cpp:743 time=2010-06-03
23:37:26.901 ]:
Unexpected error in mod_passenger: Cannot spawn application '/var/
www/myapp/current': The spawn server has exited unexpectedly.
Backtrace:
(empty)


Any ideas?

[Hongli Lai]

Is that the only error? Nothing else?

Which Phusion Passenger version by the way?

RVM also throws this: /home/web/.rvm/bin/passenger_ruby: 2: source:
not found

However if I run passenger_ruby it throws this error but continues to
run properly.

[Joshua Partogi]

I am also getting this error with Ruby Enterprise Edition and
Passenger 2.2.14

Kind regard,
Joshua

Steel Fu, how does your PassengerRuby directive look like?

Joshua, does it happen to you with every request or only for some requests?

Hi Hongli Lai,


I experience this on every request. Maybe because there is a recent
update on Rails 3?

Let's find out what's going on. Can you restart your web server and
type passenger-memory-stats? What do you see?

Ok, so I just re-image'd the server and started from scratch. This
time using 2.2.14.

Got this in the logs:

This error here tells you that Ruby cannot load RubyGems and so the
spawn server (which is written in Ruby) bails out. You need to fix
your RubyGems installation.

Do you get the same error with REE?

What happens when you run gem on the command line?

Everything works fine outside of passenger. I can run the app w/
webrick w/ "rails server" and I it works fine w/ Unicorn.

I'm guessing that your Ruby installation depends on some environment
variables that are set in the shell, but not in Apache/Nginx.
Apache/Nginx are usually started through a different mechanism and
doesn't inherit environment variables from the shell.

Let's compare the load paths between Ruby on the shell and Ruby as
started by the web server.

Can you type this in the shell and paste its output:
$ set
$ irb
>> require 'rubygems'
>> puts $LOAD_PATH
>> exit

Can you also modify
/home/web/.rvm/gems/ruby-1.9.2-preview3/gems/passenger-2.2.14/lib/phusion_passenger/utils.rb?
Just before "require 'rubygems'", insert:

puts ENV.each { |a, b| puts "#{a}=#{b}" }
puts $LOAD_PATH

Then start your web server. That will cause Passenger's environment
and load path to be printed to the web server error log. Can you paste
that?

Actually, now that I think about it, this error message is also highly
suspicious:

"/home/web/.rvm/bin/passenger_ruby: 2: source: not found"

I think this means you didn't set RVM's passenger_ruby script
correctly. Can you re-run 'rvm <some ruby name> --passenger' to have
passenger_ruby regenerated and check whether the problem still occurs?

[Joshua Partogi]

Same here. Everything works fine with webrick, thin and Unicorn. I
even tried using Ruby 1.9.3-dev but caused passenger to fail also. =(

But does it fail for you with the exact same error? Emphasis on
*exact*; depending on the error message the reason why it fails can be
totally different.

Have you tried following the load path and environment check
instructions that I sent to Steel Fu?

OK. Solved.

The "source: not found" looked really odd. After investigating I found
this: http://stackoverflow.com/questions/670191/getting-a-source-not-found-error-when-using-source-in-a-bash-script

RVM's wrapper script started with "#!/usr/bin/env sh", when I changed
it to "#!/bin/bash" it all worked fine.

Thank god, now I can move on with my life. Hope this fixes it for the
other guys as well.

FWIW, this was fixed last week in RVM head: rvm update --head
