MultiDaemons

It provides an easy way to run multiple ruby scripts as daemon. Daemon can be controlled by start, stop and restart. It also supports blocks as daemons. It even supports running single daemon process like other popular daemonzing gems.

Installation

Add this line to your application's Gemfile:

gem 'multi_daemons'

And then execute:

$ bundle

Or install it yourself as:

$ gem install multi_daemons

Usage

To run multiple daemons.

# this is server.rb

proc_code = Proc do
  loop do
    sleep 5
  end
end

scheduler = MultiDaemons::Daemon.new('scripts/scheduler', name: 'scheduler', type: :script, options: {})
looper = MultiDaemons::Daemon.new(proc_code, name: 'looper', type: :proc, options: {})
MultiDaemons.runner([scheduler, looper], { force_kill_timeout: 60 })

To run as daemon

ruby server.rb start
ruby server.rb stop
ruby server.rb restart

To run single daemon within a script.

proc_code = Proc do
  loop do
    sleep 5
  end
end
looper = MultiDaemons::Daemon.new(proc_code, name: 'looper', type: :proc, options: {})
looper.start # start daemon
# Do some other activity
looper.stop # stop daemon

To run single daemon.

proc_code = Proc do
  loop do
    sleep 5
  end
end
looper = MultiDaemons::Daemon.new(proc_code, name: 'looper', type: :proc, options: {})
MultiDaemons.runner([looper], { force_kill_timeout: 60 })

Supported options for runner:
