I’m trying to get a daemon to work on debian using daemons gem. I
installed daemons
via gems and I’m running version 1.0.3.
I used daemon_generator from
I created a daemon called test and ran it on OSX with no problem,
meaning that
./script/daemons start
and
./script/daemons stop
both work fine.
I moved it to a debian system, modifed test.rb to use the production
environment, and I can’t get it to work. I’ve tried a bunch of things.
It
doesn’t seem to start reliably
On the debian system
./script/daemons start
sometimes works. I see the daemon running, I see the monitor daemon
running, and
messages are going into the production log file.
If I try to stop it with
./script/daemons stop
the test daemon stops but the monitor does not stop. Then I get a log
file for
the test daemon with

Here is lib/daemons/test.rb:
#!/usr/bin/env ruby
#You might want to change this
ENV[“RAILS_ENV”] ||= “production”
require File.dirname(FILE) + “/…/…/config/environment”
$running = true;
Signal.trap(“TERM”) do
$running = false
end
while($running) do
Replace this with your code
ActiveRecord::Base.logger << “This daemon is still running at
#{Time.now}.\n”
sleep 10
end
and here is the ctl file:
#!/usr/bin/env ruby
require ‘rubygems’
require “daemons”
require ‘yaml’
require ‘erb’
require ‘active_support’
options = YAML.load(
ERB.new(
IO.read(
File.dirname(FILE) + “/…/…/config/daemons.yml”
)).result).with_indifferent_access
options[:dir_mode] = options[:dir_mode].to_sym
Daemons.run File.dirname(FILE) + ‘/test.rb’, options
