tiny_daemon

• It daemonizes a Ruby block and supports graceful exiting.
• It only supports and guarantee running only one process at any moment

How to use

Please include this into your Gemfile:

gem 'tiny_daemon'

p = TinyDaemon.new("test_process", "pids", "log")

p.stop # Allow only one instance to run at any moment

p.exit do
  is_running = false
  puts "The process #{Process.pid} is being killed gracefully "
end

p.start do
  while is_running
    puts "Test"
    sleep(1)
  end

  puts "The process #{Process.pid} exited gracefully"
end

There will be a pid file at pids/test_process.pid. The log file will be at log/test_process.log.

We can issue kill [pid] in order to exit the process gracefully. Please note that using kill -9 [pid] will terminate the process immediately.
