Question

我有以下dameon：

#!/usr/bin/ruby
require 'rubygems' unless defined?(Gem)
require 'forever'
require 'mongoid'

ENV["RAILS_ENV"] ||= "production"
require File.expand_path("../../../config/environment", __FILE__)
Mongoid.load!("../../config/mongoid.yml")


Forever.run do
  every 1.minutes do
    @booking = Booking.where(booking_available: false, :created_at.lt => DateTime.now.to_datetime.in_time_zone("Madrid") - 10.minutes).to_a
    @booking.each do |book|
      if book.Ds_Response.nil?
        book.booking_available = true
        book.save
        puts "update #{book.id}"
      end
    end
    puts "#{@booking.count}"
  end
end

这项工作非常适合我的开发环境，但当我尝试在我的服务器上部署此守护程序时，我收到以下错误：

executing "cd /home/web/apps/pre.blabloo.com/current && RACK_ENV=pre bundle exec ruby script/user/booking_release.rb start

我在生产服务器上部署此守护程序时缺少的是什么。

提前感谢您的帮助。

更新

这是我的mongoid.yml文件的路径：

web@app0:~/apps/pre.blabloo.com/current$ cd config
web@app0:~/apps/pre.blabloo.com/current/config$ ls
application.rb  database.yml  deploy_tasks    environments  initializers  mongoid.yml   routes.rb
boot.rb     deploy.rb     environment.rb  facebook.yml  locales   newrelic.yml  unicorn.rb

它上面的守护进程

blabloo/script/user/booking_release.rb

主要问题是配置文件mongoid.yml是用相对路径指定的。

如果查看Mongoid.load!方法的实现，您将看到该文件最终由File.new方法打开。 File.new方法尝试使用进程的当前工作目录来查找配置文件。

示例：

/Users/xxxx/Workspace/sandbox_projects中的文件树：

tmp_20150211 |-- config.rb |-- root | |-- tree | | |-- leaf.rb

档案leaf.rb：

# Returns the actual absolute path of the config.rb file File.expand_path('../../../config.rb', __FILE__) # Returns the path that is used to locate the config.rb file File.expand_path('../../config.rb') File.exists?('../../config.rb')

当我在leaf.rb目录（tmp_20150211）中运行$ ruby root/tree/leaf.rb文件时，无法找到config.rb文件：

File.expand_path('../../../config.rb', __FILE__) #=> /Users/xxxx/Workspace/sandbox_projects/tmp_20150211/config.rb File.expand_path('../../config.rb') #=> /Users/xxxx/Workspace/config.rb File.exists?('../../config.rb') #=> false

但是，当我在leaf.rb目录（tmp_20150211/root/tree）中运行$ ruby leaf.rb文件时，可以找到config.rb文件：

File.expand_path('../../../config.rb', __FILE__) #=> /Users/xxxx/Workspace/sandbox_projects/tmp_20150211/config.rb File.expand_path('../../config.rb') #=> /Users/xxxx/Workspace/sandbox_projects/tmp_20150211/config.rb File.exists?('../../config.rb') #=> true

<强>结论

要解决您的问题，请指定mongoid.yml配置文件，其中包含Mongoid.load!方法的绝对路径。要隐藏mongoid.yml配置文件的相对路径，请使用File.expand_path方法，并使用__FILE__作为dir_string参数。
