用这个拔掉我的头发后，恐怕我将不得不再次将那些知识变得更聪明......再次！

好的，这就是问题所在，我正在关注以下两个railscast：

在生产中部署到 vps
资产管道

我的设置：
Ubuntu Server 12.04
nginx
unicorn
ruby​​ 1.9.3p125
rails 3.2.2

广告据我所知，所有内容都遵循了 T（或者 Tea 或者可能是 Tee，我以前从未见过这句话被写下来）。该坐席现在在我的服务器上运行，但未加载样式表和 javascript 文件。加载公共/资产中存在的 .css 文件时，它似乎与Rails 3.1 404 错误或样式表或 JavaScript 文件的 Rails 404 错误相同。虽然第一个没有答案，但后者表明这可能是网络服务器不寻找静态资源的问题，也许不应该。

有谁知道可能是什么原因造成的？

一些事实：

  • 首先，我遇到了一些关于预编译的严重错误，并注意到我的个人 css/js 文件已被缩小为它们的应用程序对应文件，因此我在 ruby​​ 助手中更改了它们的声明以反映这一点。

  • 当我更改为config.serve_static_assets = truein时，该应用程序在本地工作config/environments/production.rb

  • 这是我服务器上生产.log 的转储

如您所见，没有更多关于预编译的投诉

这是生成的html

  <title>HTML Snippet</title>
  <link href="/assets/application-dd445a707b7e96c914afd14bf1f02bbc.css" media="screen" rel="stylesheet" type="text/css" />

  <script src="http://cloud.github.com/downloads/malsup/cycle/jquery.cycle.all.latest.js" type="text/javascript"></script>

如果我点击它们，这些链接会生成一个 nginx 404，但是如果我将 url 更改为 http://<ipaddress>/public/assets/application-dd445a707b7e96c914afd14bf1f02bbc.css我会生成一个 railsThe page you were looking for doesn't exist.

这是我服务器上 /public/assets 的重要（我认为）内容

application-7c90c01effcf9d8593e28e4c4b716ac2.css

最后，我不太清楚的领域，只是它全部覆盖，这里是 railscast 中用于配置 capistrano、nginx 和 unicorn 的文件：

If nginx isn't serving static assets it's probably due to a typo in the root directive. Triple check that it's correctly referencing your rails public folder.

In my case, I forgot that I moved my app to a different location. This didn't break the app entirely as nginx was still able to proxy_pass requests via my unicorn socket which hadn't moved.

Don't assume your app is wired up properly if you get responses from your rails app. The root directive must point to the correct folder to resolve static assets.

server {
  ...

  # make absolutely sure this is pointing to your app/public folder
  root /home/deployer/apps/blog/current/public;

  ...
}

不太确定如何执行此操作（我不确定回答您自己问题的礼仪）但我可能已经解决了问题，基本上，我认为虽然 nginx 服务器正在重新启动，但独角兽服务器没有（或者如果所以效果没有生效）。我发现这个帖子重启独角兽问题（capistrano）的解决方案似乎已经成功了。现在我只需要弄清楚如何将它连接到我的代码中！
