将Ruby程序作为Windows服务运行？

Question

是否可以将ruby应用程序作为Windows服务运行？ 我看到有一个相关的问题讨论将Java应用程序作为Windows服务运行 ，如何使用Ruby应用程序执行此操作？

Answer 1

查看以下库： Win32Utils 。 您可以创建一个简单的服务，您可以在闲暇时开始/停止/重新启动。 我目前正在使用它来管理Windows托管的Rails应用程序的Mongrel实例，它可以完美运行。

Answer 2

在尝试使用Win32Utils时，确实需要研究文档并查看网络，然后才能找到一些简单的工作示例。 这似乎今天工作2008-10-02：

gem install win32-service

更新2012-11-20：根据https://stackoverflow.com/users/1374569/paul，register_bar.rb现在应该是

Service.create( :service_name => 'some_service',
                :host => nil,
                :service_type       => Service::WIN32_OWN_PROCESS,
                :description        => 'A custom service I wrote just for fun',
                :start_type         => Service::AUTO_START,
                :error_control      => Service::ERROR_NORMAL,
                :binary_path_name   => 'c:\usr\ruby\bin\rubyw.exe -C c:\tmp\ bar.rb',
               :load_order_group   => 'Network',
               :dependencies       => ['W32Time','Schedule'],
               :display_name       => 'This is some service'       )

---

bar.rb

创建应用程序/守护程序

LOG_FILE = 'C:\\test.log'

begin
  require "rubygems"
  require 'win32/daemon'

  include Win32

  class DemoDaemon < Daemon

    def service_main
      while running?
      sleep 10
      File.open("c:\\test.log", "a"){ |f| f.puts "Service is running #{Time.now}" } 
    end
  end 

    def service_stop
      File.open("c:\\test.log", "a"){ |f| f.puts "***Service stopped #{Time.now}" }
      exit! 
    end
  end

  DemoDaemon.mainloop
rescue Exception => err
  File.open(LOG_FILE,'a+'){ |f| f.puts " ***Daemon failure #{Time.now} err=#{err} " }
  raise
end

bar.rb是服务，但我们必须先创建并注册！ 这可以通过sc create some_service来完成

但如果我们要使用ruby和win32utils，我们应该做一个

register_bar.rb

 require "rubygems"
require "win32/service"
   include Win32



   # Create a new service
   Service.create('some_service', nil,
      :service_type       => Service::WIN32_OWN_PROCESS,
      :description        => 'A custom service I wrote just for fun',
      :start_type         => Service::AUTO_START,
      :error_control      => Service::ERROR_NORMAL,
      :binary_path_name   => 'c:\usr\ruby\bin\rubyw.exe -C c:\tmp\ bar.rb',
      :load_order_group   => 'Network',
      :dependencies       => ['W32Time','Schedule'],

      :display_name       => 'This is some service'
   )

---

请注意，'c：\\ usr \\ ruby​​ \\ bin \\ ruby​​w.exe -C c：\\ tmp \\ bar.rb'中c：\\ tmp \\ bar.rb之间有一个空格

运行ruby register_bar.rb ，现在可以从Windows服务控制面板启动该服务

sc start some_service

并观看c：test.log充满服务正在运行Thu Oct 02 22:06:47 +0200 2008

为了简单地使用它，更容易删除服务寄存器并创建一个新的服务寄存器而不是修改现有的服务寄存器

unregister_bar.rb

 require "rubygems"
    require "win32/service"
       include Win32

    Service.delete("some_service")

Answer 4

您可以编写（或下载）包装器服务。 包装器可以调用ruby.exe来执行您的程序。 同样的技巧适用于Java，VB等。

Answer 5

您应该能够在IronRuby中完成此任务，因为您将拥有.NET框架。
