Ruby on rails Unicorn/nginx/rails4通过mina部署-504网关超时和Unicorn日志中的错误

编辑。。。。 我试过用Cap和puma来设置整个过程，puma给我的错误和unicorn一样。似乎与积极的支持有关

任何帮助

我将结束这个问题，尽管我还没有找到答案……但我发现这就是问题所在：

Unable to load application: LoadError: No such file to load -- Find

我有一个控制器，我可以：

require 'Find'

class CatalogsController < ApplicationController
...

需要“查找”
类CatalogsController

---

当我删除“require Find”时，一切正常。我留下了一个新问题，关于如何在控制器中要求模块（查找）？

您有两个具有相同

listen

和

server\u name

的服务器块。那不行。我修复了它，它删除了一些警告，但没有修复问题…：-(

require 'Find'

class CatalogsController < ApplicationController
...
