无法通过远程计算机重新启动精简 [英] Cannot restart thin via remote machine

问题描述

我使用Thin来服务位于测试机器上的导轨应用程序。我希望能够停止/从我的本地机器开始瘦，但以下不起作用：

  ssh luc @ test_machine'/home/luc/.rvm/gems/ruby-1.9.3-p125/bin/thin -v'
  

我收到以下错误消息：

  /home/luc/.rvm/rubies/ruby-1.9。 3-p125 / lib / ruby​​ / site_ruby / 1.9.1 / ruby​​gems / dependency.rb：247：in`to_specs'：在[bigdecimal-1.1.0，io-console-0.3]之间无法找到稀疏（> = 0） ，json-1.5.4，minitest-2.5.1，rake-0.9.2.2，rdoc-3.9.4]（Gem :: LoadError）
 from /home/luc/.rvm/rubies/ruby-1.9。 3-p125 / lib / ruby​​ / site_ruby / 1.9.1 / ruby​​gems / dependency.rb：256：来自/home/luc/.rvm/rubies/ruby-1.9.3-p125/lib的`to_spec'

 from /home/luc/.rvm/gems/ruby-1.9.3-p125/bin/thin:18:in` < main>'
  

当我有分数时，为什么只列出6个宝石？

当我在ssh连接到测试服务器时：

 哪个瘦
  

给了我正确的路径：

  /home/luc/.rvm/gems/ruby-1.9.3-p125/bin/thin（问题用正确路径更新）
  

更新

我创建了一个基本的test.sh脚本在服务器上：

 ＃！/ bin / bash 
＃使用ruby / gem更新路径
 export PATH = $ PATH：/home/luc/.rvm/rubies/ruby-1.9.3-p125/bin:/home/luc/.rvm/gems/ruby-1.9.3-p125/bin/ 
 thin -v 
 exit 0 
  

我从本地机器调用它

  ssh luc @ test_machine'/home/luc/test.sh'
  

但仍然是找不到细错误。

UPDATE 2

这可能与使用的rubies / gemset该脚本通过ssh运行。我已添加

  rvm list 
 rvm gemset list 
  

在test.sh文件中，输出结果是：

  rvm rubies 
 
 * ruby​​-1.9.3-p125 [x86_64] 
 
＃=> - 当前
＃= *  - 当前&&默认
＃*  - 默认
 
系统的gemsets（位于/home/luc/.rvm/gems/system）
 * 
  

似乎我安装的宝石不存在......不知道要通过ssh调用来说明使用的rubies / gemset版本尽管如此。

解决方案

我用另一种方式管理这个。我没有试图从远程计算机重新启动服务器，而是安装了gemrerun（https://github.com/alexch/rerun），以便在更改某些代码时自动完成瘦服务器的重新启动。

 重新运行 - 瘦开始
  

真的很好

I use Thin to serve the rails application located on a test machine. I'd like to be able to stop/start thin from my local machine but the following does not work:

ssh luc@test_machine '/home/luc/.rvm/gems/ruby-1.9.3-p125/bin/thin -v'

I got the following error message:

/home/luc/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in `to_specs': Could not find thin (>= 0) amongst [bigdecimal-1.1.0, io-console-0.3, json-1.5.4, minitest-2.5.1, rake-0.9.2.2, rdoc-3.9.4] (Gem::LoadError)
from /home/luc/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:256:in `to_spec'
from /home/luc/.rvm/rubies/ruby-1.9.3-p125/lib/ruby/site_ruby/1.9.1/rubygems.rb:1230:in `gem'
from /home/luc/.rvm/gems/ruby-1.9.3-p125/bin/thin:18:in `<main>'

Why does it list only 6 gems when I have scores ?

When I'm connected in ssh onto the test server:

which thin

gives me the right path:

/home/luc/.rvm/gems/ruby-1.9.3-p125/bin/thin  (question updated with correct path)

UPDATE

I have created a basic test.sh script on the server:

#!/bin/bash
# Update path with ruby / gem
export PATH=$PATH:/home/luc/.rvm/rubies/ruby-1.9.3-p125/bin:/home/luc/.rvm/gems/ruby-1.9.3-p125/bin/
thin -v
exit 0

I call it from my local machine

ssh luc@test_machine '/home/luc/test.sh'

But still the same "could not find thin" error.

UPDATE 2

This might be linked to the rubies / gemset used when the script is run through ssh. I have added

rvm list
rvm gemset list

in the test.sh file and the output I have is:

rvm rubies

* ruby-1.9.3-p125 [ x86_64 ]

# => - current
# =* - current && default
#  * - default

gemsets for system (found in /home/luc/.rvm/gems/system)
*

It seems that the gems I have installed are not there... Don't know to spefify the rubies/gemset version to use through a ssh call though.

解决方案

I managed this using another way. Instead of trying to restart the server from a remote machine, I installed the gem "rerun" (https://github.com/alexch/rerun) so the restart of the thin server is done automatically when some code is changed.

rerun -- thin start

does the trick really well
