Capistrano V3在database.yml上失败

2018-06-26 19:44:34

我正在使用最新版本的Capistrano w /我的Rails 4应用程序。运行cap dpeloy 。我得到了很多输出，包括这个失败：

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).

我怎么知道这里发生了什么？

更新＃1

我应该说我拥有gitignored config/database.yml （正如Capistrano文档所建议的那样）。然后我将以下内容添加到我的config/deploy.rb

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

然后我在VPS上的/var/www/skateboxes/shared/config/database.yml创建了一个文件。

我不理解linked_files的工作原理吗？

更新＃2

事实证明，该文件实际上是从shared/conf/database.yml到current/config/database.yml所以现在我很困惑，为什么它说failed

更新＃3

这是我部署的完整输出

这不是一个失败，请参阅https://github.com/leehambley/sshkit/pull/33。

它说failed因为这不是一个文件，因此测试命令（ [又名man (1) test ）已退出状态1 。

有问题的命令正在出现这个代码，转载如下：

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

如果您的文件列在:linked_files变量中，它就必须存在于shared_path ，否则在文件不存在时会导致Capistrano中止。

您还没有说过这是否会导致您的部署失败，并且由于您发布的日志很少，除了正常行为外没有任何其他信息，所以没人能猜到。

你似乎张贴从日志Symlink linked files的任务，这是应该fail上config/database.yml ，如果它不存在，它failed找到它，所以它并没有被删除。
