我无法运行我的Rails应用程序与守护进程宝石 [英] I can't run my Rails application with daemons gem

问题描述

我想使用Daemons宝石与我的Rails项目，所以我可以轻松地监视它与Monit，这个宝石将允许我创建PID，并使用命令，如开始和停止。

无论如何，我似乎无法使用rails，我创建一个文件并命名为admin：

  require 'rubygems'
 require'daemons'
 
 ROOT_PATH = File.expand_path（＃{File.dirname __FILE __} /../）
 
 require＃ {ROOT_PATH} / config / environment
 
 Daemons.run（＃{ROOT_PATH} / script / rails，
：dir_mode =>：system，
：log_output = > true 
）
  

当我尝试运行它：

  bundle exec ./bin/admin run  -  s 
  

我收到此错误：

  /Users/info/.rvm/gems/ruby- 1.9.3-p286 / gems / rake-0.8.7 / lib / rake / alt_system.rb：32：使用RbConfig代替过时和不推荐使用的配置。 
 =>启动WEBrick 
 => Rails 3.0.5应用程序开始于http://0.0.0.0:3000 
 =>调用-d来分离
 => Ctrl-C关闭服务器
配置/config.ru未找到
退出
  

config.ru文件是肯定的。当我尝试使用命令行手动执行时，我可以运行应用程序，但由于某种原因，我可以对rails应用程序进行后台处理。

我很乐意任何帮助，因为我花了一整天的时间试图解决这个问题。

干杯

解决方案

可能是因为守护程序不在您的应用程序根目录中运行服务器？

更新

要从您的根应用程序目录的另一个路径启动Rails服务器，请使用 -c 选项 rails server 命令需要您的 config.ru 文件的确切路径。

I want to use Daemons gem with my Rails project so I can easily monitore it with Monit, this gem will allow me to create PIDs and use commands like start and stop .

Anyways it seems I can't use it with rails somehow, I create a file and named it admin :

require 'rubygems'
require 'daemons'

ROOT_PATH = File.expand_path("#{File.dirname __FILE__}/../")

require "#{ROOT_PATH}/config/environment"

Daemons.run("#{ROOT_PATH}/script/rails" , 
    :dir_mode => :system, 
    :log_output => true 
)

When I try to run it with :

bundle exec ./bin/admin run -- s

I get this error :

/Users/info/.rvm/gems/ruby-1.9.3-p286/gems/rake-0.8.7/lib/rake/alt_system.rb:32: Use RbConfig instead of obsolete and deprecated Config.
=> Booting WEBrick
=> Rails 3.0.5 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
configuration /config.ru not found
Exiting

The config.ru file is there for sure. and I can run the application when I try to do it manually with command line, but for some reason I can daemonize the rails app .

I would appreciate any help since I spent all my day trying to iron this out .

Cheers

解决方案

May it be because daemons is not running the server in your application root directory ?

UPDATE

To launch Rails server from another path than your root app directory, use the -c option of rails server command which need the exact path to your config.ru file.
