乘客似乎没有运行 (Capistrano/Rails/Nginx/Ubuntu)

Question

我正在Ubuntu 14.4、Ruby 2.3.3、Nginx和Passenger 中部署我的应用程序。当我使用 部署时capistrano，出现错误：

SSHKit::Command::Failed: passenger-config exit status: 1
passenger-config stdout: Nothing written
passenger-config stderr: *** 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 one of:

 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 this command 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.

Tasks: TOP => passenger:restart
(See full trace by running task with --trace)
The deploy has failed with an error: Exception while executing as user@IP-Address: passenger-config exit status: 1

但没有任何帮助！我已经检查了我的 Nginx default_sites 以查看我是否指向当前的 rails 路径并且一切看起来都正确。

任何帮助表示赞赏！

这个问题是固定的，加入restart.txt在my_app_name/current/tmp：

*它是在服务器中完成的：

*touch my_app_name/current/tmp/restart.txt

并添加：

set :passenger_restart_with_touch, true 在 deploy.rb

更新

在最新版本的 capistrano 中，这是通过gem 'capistrano-passenger'添加添加require 'capistrano/passenger'到您的capfile
