Ruby on rails ActionController:：RoutingError（没有任何路由与所有页面的[GET]/"；匹配）

使用Capistrano部署后，我得到

ActionController:：RoutingError（没有与production.log中的所有页面相匹配的[get]“/”

（请参见404页）。我可以通过rake路线看到所有路线-它们都很好！！！我现在该怎么办

Production.log：

Started GET "/" for 79.143.104.251 at 2012-06-24 23:53:06 +0400

问题是您可能更改了路由器或型号，但没有重新启动。要查看这些更改，必须重新启动服务器。

哪个日志？NginX、Unicorn或app？为什么Ruby/1.9.1出现错误？我的

ruby-v=ruby 1.9.3p194

我确实重新启动了所有远程服务器，现在一切正常。问题是？？？
