我们刚刚安装了一个带有乘客的 Ubuntu 18.04 新盒子，一切都运行良好，网站已经启动，但是当我们这样做时

passenger-status

我们得到

ERROR: Phusion Passenger doesn't seem to be running. If you are sure that it is running, then the causes of this problem could be:

1. You customized the instance registry directory using Apache's PassengerInstanceRegistryDir option, Nginx's passenger_instance_registry_dir option, or Phusion Passenger Standalone's --instance-registry-dir command line argument. If so, please set the environment variable PASSENGER_INSTANCE_REGISTRY_DIR to that directory and run passenger-status again.
2. The instance directory has been removed by an operating system background service. Please set a different instance registry directory using Apache's PassengerInstanceRegistryDir option, Nginx's passenger_instance_registry_dir option, or Phusion Passenger Standalone's --instance-registry-dir command line argument.

找不到解决此问题的另一个问题，它是全新安装，有什么想法吗？

谢谢，凯文

我有一个 CentOS 服务器，我们进行了 Retina 安全扫描。我不知道如何修复这个漏洞。你能为我指出正确的方向吗？我们正在运行 nginx。
