Question

我有一个使用Nginx和Unicorn托管的Sinatra应用程序。当我在服务器上升级操作系统（Ubuntu 14.04.5 LTS）时它崩溃了，我能够将它们全部备份，除了这个，基于Rack的单独应用程序。当我尝试启动Unicorn（unicorn -c unicorn.rb -D）时，我收到以下错误：

任何人都知道如何解决这个问题？感谢。

Answer 1

执行以下两个步骤后，它已修复：

如此服务器故障answer中所述，我将应用程序所有者“deployer”的组从“deployer”更改为“staff”。
我将套接字文件的所有者更改为deployer:staff（sudo chown deployer:staff /tmp/unicorn.wheels-within-wheels.sock）。

然后我运行bundle update来更新宝石，最后Unicorn成功运行并且应用程序再次运行。

以下链接表示将MacOSX升级到El Capitan时出现了一些问题。如果您可以遵循相同的路径，也许您可以解决问题。

ERROR: While executing gem ... (Errno::EPERM) Operation not permitted

Unicorn + Sinatra + Nginx |添加侦听器
