Ruby脚本作为服务 [英] Ruby script as service

问题描述

好吧，标题说的一切。我有一个ruby脚本我想运行作为一个服务（一个我可以启动和停止）在我的Linux盒子。我可以在Windows 此处找到如何执行此操作。

Well, the title say it all. I have a ruby script I want running as a service (one I can start and stop) on my Linux box. I was able to find how to do it on Windows here

有些读数指向创建守护程序或cron任务。

Some readings point to creating daemons or cron tasks.

我只需要一些简单的东西，盒的重新启动，并可以停止/开始每当我。我的脚本有一个内部睡眠调用，并运行在永恒循环

I just need something simple I can call on my box's reboot, and can stop/start whenever I please. my script has an internal sleep call, and runs in "eternal loop"

提前感谢

推荐答案

我实际上找到了一个更好的方式，通过使用ruby脚本。

I've actually found a much better way of doing that by using ruby scripts.

这是我做的：

首先，我安装了守护程序

First of all, I installed daemon

gem install daemons

然后我：

require 'rubygems'
require 'daemons'

pwd  = File.dirname(File.expand_path(__FILE__))
file = pwd + '/runner.rb'

Daemons.run_proc(
   'my_project', # name of daemon
   :log_output => true
 ) do
   exec "ruby #{file}"
end

然后我创建一个名为runner.rb的文件，调用我的脚本如：

I then create a file called runner.rb, in which I can call my scripts such as:

require "/var/www/rails/my_project/config/environment"
Post.send('details....')

Daemons是一个伟大的宝石！

Daemons is a great gem!
