Capistrano部署unicorn ERROR未初始化的常量RAILS_ENV（NameError）

Question

我刚使用Rubber＆amp; amp;成功将我的RoR应用程序部署到AWS Capistrano的。但是，当我导航到页面时，它会显示默认的nginx页面。很明显，我在设置阶段错过了一些东西，将nginx / unicorn指向正确的目录来为我的应用程序提供服务。

当我运行tail -f log/unicorn.stderr.log时，我看到以下内容：

E, [2015-12-07T14:23:41.253757 #3808] ERROR -- : reaped #<Process::Status: pid 24405 exit 1> worker=0

/ebs/microposts2-production/shared/bundle/ruby/2.0.0/bin/unicorn_rails:23:in `<main>'

我认为，因为环境附加到我的应用名称Rubber.env已存在，但是这个错误让我想到了。哎呀，我甚至不确定这个问题是否适用于nginx默认页面问题。有人可以分享我做错了什么，或错过了什么？

对于任何人来说，修复独角兽模板5.0+都可行，请参考：

Answer 2

您需要通常在/etc/nginx/sites-enabled/default清除默认的nginx虚拟主机，只需删除该文件然后就可以了。
