Lightweight Daemond Scheduler Solution

Run

ruby daemond.rb start

Why not use Daemons.run_proc?

When use Daemons.run, the scheduler will correctly restart once it cashed. But Daemons.run_proc seems not to work at all except restart the process.

daemon.rb

require 'rubygems'
require 'daemons'

Daemons.run 'scheduler.rb', :dir_mod => :write,
                            :dir => "#{File.dirname(__FILE__)}/tmp/pids",
                            :backtrace => true,
                            :monitor => true,
                            :log_output => true

Gemfile

source 'https://rubygems.org'

gem 'rufus-scheduler'
gem 'daemons'

scheduler.rb

require 'rubygems'
require 'rufus-scheduler'

scheduler = Rufus::Scheduler.new

times = 1
log = "#{File.dirname(__FILE__)}/scheduler.log"

scheduler.every '3s' do
    # Do something
    puts "==>times: #{times}"
    File.write( log,"times: #{times}")
    times += 1
end

scheduler.join
