Daemons Rails support (based on http://github.com/dougal/daemon_generator)

To get it work just add dependency to this gem in your Gemfile.

GENERATOR

rails generate daemon <name>

Then insert your code in the lib/daemons/<name>.rb stub. All pids and logs will live in the normal log/ folder. This helps to make things Capistrano friendly.

CONTROL

Individual control script:

./lib/daemons/<name>_ctl [start|stop|restart|status]
rake daemon:<name>[:(start|stop|status)]

Examples:

rake daemon:test - runs lib/daemons/test.rb not daemonized
rake daemon:test:start - start daemon using lib/daemons/test_ctl start
rake daemon:test:stop - stop daemon using lib/daemons/test_ctl stop
rake daemon:test:status - show running status for daemon using lib/daemons/test_ctl status

App-wide control script:

./script/daemons [start|stop|restart]
rake daemons:(start|stop|status)

MONITORING API

Daemons::Rails::Monitoring.statuses - hash with all daemons and corresponding statuses
Daemons::Rails::Monitoring.start("test.rb") - start daemon using lib/daemons/test_ctl start
Daemons::Rails::Monitoring.stop("test.rb") - start daemon using lib/daemons/test_ctl stop
Daemons::Rails::Monitoring.controllers - list of controllers
Daemons::Rails::Monitoring.controller("test.rb") - controller for test.rb application

controller = Daemons::Rails::Monitoring.controller("test.rb")
controller.path # => lib/daemons/test_ctl
controller.app_name # => test.rb
controller.start # => starts daemon
controller.stop # => stops daemon
controller.status # => :not_exists or :running

CHANGES

• 1.0.0 - changed api for Daemons::Rails::Monitoring, fixed path in template for script, improved documentation, added RSpec
