Capistrano V3在database.yml上失敗

Question

我正在使用最新版本的Capistrano w/my Rails 4應用程序。運行時cap dpeloy。我得到了很多輸出，包括這種故障：

DEBUG [04b6e226] Running /usr/bin/env [ -f /var/www/skateboxes/releases/20131022135522/config/database.yml ] on 162.243.33.179 
DEBUG [04b6e226] Command: [ -f /var/www/skateboxes/releases/20131022135522/config/database.yml ] 
DEBUG [04b6e226] Finished in 0.280 seconds with exit status 1 (failed). 

我該如何弄清楚這裏發生了什麼？

更新＃1

我應該說，我gitignored config/database.yml（如由Capistrano的文檔建議）。然後添加以下到我的config/deploy.rb

set :linked_files, %w{config/database.yml} 

我然後在/var/www/skateboxes/shared/config/database.yml創建了我的VPS文件。

我不理解如何linked_files工作？

更新＃2

事實證明，該文件實際上是被鏈接的shared/conf/database.yml到current/config/database.yml所以現在我很困惑，爲什麼它說failed

更新＃3

這裏是我部署的整個輸出

Answer 1

這不是故障，請參閱https://github.com/leehambley/sshkit/pull/33。

它說failed因爲那是不文件，因此測試命令（[又名man (1) test）已經退出，狀態1。

有問題的命令出來的this code，轉載如下：

desc 'Symlink linked files' 
task :linked_files do 
    next unless any? :linked_files 
    on roles :app do 
    execute :mkdir, '-pv', linked_file_dirs(release_path) 

    fetch(:linked_files).each do |file| 
     target = release_path.join(file) 
     source = shared_path.join(file) 
     unless test "[ -L #{target} ]" 
     if test "[ -f #{target} ]" 
      execute :rm, target 
     end 
     execute :ln, '-s', source, target 
     end 
    end 
    end 
end 
desc 'Check files to be linked exist in shared' 
task :linked_files do 
    next unless any? :linked_files 
    on roles :app do |host| 
    linked_files(shared_path).each do |file| 
     unless test "[ -f #{file} ]" 
     error t(:linked_file_does_not_exist, file: file, host: host) 
     exit 1 
     end 
    end 
    end 
end 

任務名字說明了一切，真的，如果你的文件在:linked_files變量中列出，它必須存在於shared_path，否則它會導致Capistrano在文件不存在時中止。

您還沒有說過這是否會導致您的部署失敗，並且由於您發佈的日誌很少，除了正常行爲外沒有任何其他信息，所以沒人能猜到。

你似乎從Symlink linked files任務，這是應該fail上config/database.yml，如果它不存在，發佈日誌，它有failed找到它，所以它並沒有被刪除。
