独角兽+Sinatra+Nginx |添加侦听器的致命错误

Question

我有一个使用 Nginx 和 Unicorn 托管的 Sinatra 应用程序。当我升级服务器上的操作系统 (Ubuntu 14.04.5 LTS) 时，它出现故障，我能够将它们全部备份，除了这个，唯一的基于 Rack 的应用程序。当我尝试启动 Unicorn (unicorn -c unicorn.rb -D) 时，出现以下错误：

有人知道如何解决这个问题吗？谢谢

Answer 1

下面的link说的是MacOSX升级到El Capitan时出现的那种问题。如果你能走同样的路，也许你就能解决问题。

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

Answer 2

在我执行了以下两个步骤后，它已修复：

如服务器故障 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更新gems，最后Unicorn运行成功，应用又上线了。
