我在 Capistrano 的第一天，我完全是 Ruby 菜鸟。当我跑步时，cap production deploy我得到：（大约在中途你会看到“cap aborted！”）

Tasks: TOP => deploy:restart
(See full trace by running task with --trace)

我真的不确定这里的问题是什么，我在文档中没有看到任何关于 Capistrano 和过滤器的内容。

不确定还有哪些其他信息与此处相关，所以如果我遗漏了任何内容，请告诉我。

谢谢！

Capistrano 3 的部署任务依赖于名为 deploy:restart 的任务。与默认部署流程中的其他任务不同，deploy:restart 的行为不是为您预定义的；您需要根据您使用的应用程序服务器对其进行自定义。当您运行时，cap install会创建一个骨架任务供您在 Capfile 中进行编辑，如下所示。

desc 'Restart application'
task :restart do
  on roles(:app), in: :sequence, wait: 5 do
    # Your restart mechanism here, for example:
    # execute :touch, release_path.join('tmp/restart.txt')
  end
end

on roles(:app)告诉 capistrano 在您在config/deploy/production.rb中赋予应用角色的服务器上执行此方法。我认为您没有为任何服务器分配此角色，因此 capistrano 抱怨它没有任何地方可以运行此任务。现在，您可以修改此任务以在另一个角色上运行。但是，与链接文件和目录相关的预定义任务也涉及应用角色，因此如果您开始使用它们（例如，对于 database.yml），capistrano 会再次抛出此错误。因此，我认为更好的选择是给你的服务器应用角色。
