Ruby on Rails Server选项[关闭]

问题：

The whole issue of setting up a development server for my Ruby on Rails application confuses me. 为我的Ruby on Rails应用程序设置开发服务器的整个问题使我感到困惑。 There are WEBrick, Mongrel, Passenger, Apache, Nginx and many more I am sure, and I don't really understand the different roles they play. 我敢肯定，有WEBrick，Mongrel，Passenger，Apache，Nginx等等，我真的不了解他们扮演的不同角色。

I started off using WEBrick, and now I use Mongrel for development. 我开始使用WEBrick，现在使用Mongrel进行开发。 Are these servers stand-alone, or do they sit in front of Apache? 这些服务器是独立的还是位于Apache的前面？

I have read about Passenger and I don't really understand what it is, the site says "makes deployment of Ruby web applications a breeze", does it replace Mongrel? 我已经阅读了有关Passenger的文章，但我并不十分了解它的含义，该网站说“使Ruby Web应用程序的部署变得轻而易举”，它可以代替Mongrel吗？ Is it like Capistrano, which also deploys web applications? 就像Capistrano一样，它也部署Web应用程序吗？

Bearing in mind I would like to test SSL, and I believe that's not supported by mongrel, what is the best development server setup? 请记住，我想测试SSL，并且我认为mongrel不支持SSL，最好的开发服务器设置是什么？

Thanks 谢谢
