我在使用rails应用程序在生产中运行时遇到了一些麻烦。由于我之前编写过rails，但是没有部署很多，这可能是我的配置和/或部署过程中的一些内容。
在开发过程中，一切都运行良好。所有测试都通过，我可以看到路由并在localhost访问它们。在生产中（rails 4，nginx，CentOS上的独角兽）我在同一条路线上遇到500个错误。
当我在服务器上搜索路由时，我看到与开发时相同的路由。服务器上的Rake路由返回（从完整的路由列表缩短）：
Prefix Verb URI Pattern Controller#Action
companies GET /companies(.:format) companies#index
POST /companies(.:format) companies#create
new_company GET /companies/new(.:format) companies#new
edit_company GET /companies/:id/edit(.:format) companies#edit
company GET /companies/:id(.:format) companies#show
PATCH /companies/:id(.:format) companies#update
PUT /companies/:id(.:format) companies#update
DELETE /companies/:id(.:format) companies#destroy
您可能猜到的来自资源：公司
但是http://sortinghat.foo.com/companies给了我生产500页的轨道（foo显然不是域名，但我刚刚取代了真正的域名。）
我在这里和网上寻找想法，阅读了大量的“如何部署rails”博客帖子，看了很多配置文件，我感到很遗憾（你会看到这些是我从中复制过的文件）在其他地方，但似乎都很标准）。我可能错过了一些明显的东西。我没有在日志中看到任何问题。
我唯一的线索是我没有/ etc / nginx / sites-enabled目录，看起来像capistrano想要一个，但我没有看到帽子部署期间的任何错误（除了清理一个我请注意底部）。在这种情况下，它是唯一运行的站点，因此我不需要虚拟主机，并且认为我不需要它，所以不关心。
提前感谢您的帮助。
这是我的nginx.config

和我的deploy.rb（注意：我用 chmod 777 作为一个快速入侵使得一些东西可以读取。我只是想让它在内部运行以运行测试防火墙。我可以把它拿出去，但我怀疑它们现在正在伤害任何东西。）

cap deploy 只能处理一个错误，但这只是清理旧版本的权限问题。 （上限部署：冷运行良好）

答案 0 :(得分：-1)
朋友的回答是：使用乘客，而不是独角兽。它几乎开箱即用。
您可以在https://www.phusionpassenger.com/
找到它（我确实有一些奇怪的问题，我从github得到了错误128.我的deploy.rb没有任何改变，除了取消注释底部的注释用于乘客;当然我的github帐户或AFAIK本地没有任何改变。我不确定发生了什么，但我删除了我的github密钥，创建了一个新的，然后一切正常。）
