Phusion Passenger目前不提供任何申请

I got error like Phusion Passenger is currently not serving any applications. while trying to restart passenger with passenger-config restart-app command.

我得到的错误就像Phusion Passenger目前没有提供任何应用程序。尝试使用passenger-config restart-app命令重新启动乘客。

I googled but most of the answers were only related with deployment.

我用谷歌搜索，但大多数答案只与部署有关。

I want to restart passenger in the development environment as I am using vhost. PS. My web server is nginx.

我想在开发环境中重新启动乘客，因为我正在使用vhost。 PS。我的网络服务器是nginx。

See my comment here.

在这里看我的评论。

You need to explicitly specify, where actual Ruby code of a Rails application is located, using passenger_app_root directive, described in Passenger's documentaion.

您需要使用乘客的文档中描述的passenger_app_root指令显式指定Rails应用程序的实际Ruby代码所在的位置。

Without this directive, Passenger will thinck, that actual Ruby code is located in path, specified with root nginx-directive.

如果没有这个指令，Passenger将会瘦，实际的Ruby代码位于路径中，使用root nginx-directive指定。

Example of a correct configuration file '/etc/nginx/sites-available/app_name':

正确配置文件'/ etc / nginx / sites-available / app_name'的示例：

server {
  listen 80;

  server_name 188.225.35.216;
  passenger_enabled on;
  rails_env    production;
  root         /path/to/your/app/public/folder;
  passenger_app_root /path/to/your/app/code; # <<< Point Passenger to application code

  # redirect server error pages to the static page /50x.html
  error_page   500 502 503 504  /50x.html;
  location = /50x.html {
    root   html;
  }
}

In my case, Passenger was't serving my Rails app, that was deployed with Capistrano. I had have to specify a value for passenger_app_root like following /var/www/my_app/current.

就我而言，Passenger没有为我的Rails应用程序提供服务，该应用程序是与Capistrano一起部署的。我必须为后面的/ var / www / my_app / current指定passenger_app_root的值。

This will point Passenger exactly, where application code is presented.

这将准确指出Passenger，其中显示了应用程序代码。

I am betting your passenger is running.
If you look at step 3, it hints at what I am talking about.

我打赌你的乘客正在跑步。如果你看第3步，就会暗示我在说什么。

Nginx will take care of passenger for you if it's set up to do that. Can you try the command in that tutorial and look for passenger processes too ?

如果设置的话，Nginx将为您照顾乘客。您可以尝试该教程中的命令并查找乘客流程吗？

sudo /usr/sbin/passenger-memory-stats

Good luck!

祝你好运！
