帽生產部署錯誤的Net :: SSH :: AuthenticationFailed：驗證失敗

Question

http://www.sitepoint.com/deploy-your-rails-app-to-aws/

我下面這個教程來部署我的Rails應用程序到Amazon EC2上，直到我到了到底哪裏它告訴我這樣做：

cap production deploy 

當我鍵入到哪裏我的代碼是文件夾，我得到這個錯誤：

** Invoke production (first_time) 
** Execute production 
** Invoke load:defaults (first_time) 
** Execute load:defaults 
** Invoke bundler:map_bins (first_time) 
** Execute bundler:map_bins 
** Invoke rvm:hook (first_time) 
** Execute rvm:hook 
** Invoke rvm:check (first_time) 
** Execute rvm:check

我覺得我跟着教程一切正常。這是我第一次使用EC2，我應該如何解決這個問題？

這裏是我的deploy.rb文件

    after :restart, :clear_cache do

     # within release_path do 
     # execute :rake, 'cache:clear' 
     # end 
    end 
    end 

有這一部分，我是一個有點困惑：（但不是錯誤的原因我想是因爲我有這個由於身份驗證錯誤的問題？）

set :rvm_ruby_version, 'jruby-1.7.19' # Edit this if you are using MRI Ruby 

我沒有使用JRuby

，我應該放在那裏呢？我如何找到MRI版本？

Answer 1

我有同樣的錯誤。我通過這樣做解決了這個問題：

ssh-add ~/.ssh/student-discount-ec2.pem
