Ruby on rails 4 乘客不'；t似乎正在运行（Capistrano/Rails/Nginx/Ubuntu）

我正在Ubuntu 14.4、Ruby 2.3.3、Nginx和Passenger中部署我的应用程序。使用

capistrano

部署时，会出现以下错误：

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
passenger-config stdout: Nothing written

    line argument.

我尝试了一些建议，例如：

但是没有任何帮助！我已经检查了我的Nginx default_站点，看看我是否指向当前的rails路径，并且所有内容看起来都是正确的

感谢您的帮助

通过在

我的应用程序名称/current/tmp

中添加

restart.txt

解决了此问题：

*这是在服务器上完成的：

*

触摸我的应用程序名称/current/tmp/restart.txt

并加上：

set:passenger\u restart\u触摸，在
deploy.rb中为true

更新

在capistrano的最新版本中，这由
gem'capistrano passenger'
负责，并在
capfile中添加
require'capistrano/passenger'
