【问题描述】：

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capistrano 进行部署时，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

我尝试了几个建议，例如：https://www.pistolfly.com/weblog/en/2016/01/passenger-config-and-passenger-status-result-in-an-error-on-centos7.html

Passenger doesn't seem to be running (Capistrano/Rails/Apache/Ubuntu)

但没有任何帮助！我检查了我的 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。

感谢任何帮助！

【解决方案1】：

通过在my_app_name/current/tmp 中添加restart.txt 已解决此问题：

*在服务器中完成：

*touch my_app_name/current/tmp/restart.txt

并添加：

set :passenger_restart_with_touch, true in deploy.rb

更新

在最新版本的 capistrano 中，这由 gem 'capistrano-passenger' 处理，并在您的 capfile 中添加 require 'capistrano/passenger'
