r shiny server is running, but the app is not working

We have built shiny-server on linux ubuntu, I check the status and the shiny-server.conf and both seems to be okay but not able to run the app, please see as below: 1. The shiny-server status:

  root@ubuntu:~# sudo status shiny-server
  shiny-server start/running, process 43150

  1. The server.conf

    # Instruct Shiny Server to run applications as the user "shiny"
run_as shiny;

# Define a server that listens on port 3838
server {
  listen 3838;

  # Define a location at the base URL
  location / {

    # Host the directory of Shiny Apps stored in this directory
    site_dir /srv/shiny-server;

    # Log all Shiny output to files in this directory
    log_dir /var/log/shiny-server;

    # When a user visits the base URL rather than a particular application,
    # an index of the applications available in this directory will be shown.
    directory_index on;
  }
}

However, when I put the server.R and UI.R files under srv/shiny-server and then run the URL, it is in vain and shows "Not found". 

 http://<my_server>:3838/<app_name>
Solution

  • Below code shows an allappfolders created, under which you can create various apps like app1, app2..etc.

    Below will display all apps under

    http://<my_server>:3838/allappfolders

    Below app1 will load the ui.R and server.R 

    http://<my_server>:3838/allappfolders/app1

    Full conf. code below:

    # Instruct Shiny Server to run applications as the user "shiny"
run_as shiny;

# Define a server that listens on port 3838
server {
  listen 3838;

    location /users {
      run_as :HOME_USER:;
      user_dirs;
    }

    # Define a location at the base URL
    location /allappfolders {
        run_as shiny;

        # Host the directory of Shiny Apps stored in this directory
        site_dir /opt/shiny-server/allappfolders;

        # Log all Shiny output to files in this directory
        log_dir /var/log/shiny-server/allappfolders;

        # When a user visits the base URL rather than a particular application,
        # an index of the applications available in this directory will be shown.
        directory_index on;
    };

    # Define a location at the base URL
    location /app1 {

        # Host the directory of Shiny Apps stored in this directory
        app_dir /opt/shiny-server/allappfolders/app1;

        # Log all Shiny output to files in this directory
        log_dir /var/log/shiny-server/app1;

        # When a user visits the base URL rather than a particular application,
        # an index of the applications available in this directory will be shown.
        directory_index off;
    };

    # Define a location at the base URL
    location /app2 {

        # Host the directory of Shiny Apps stored in this directory
        app_dir /opt/shiny-server/allappfolders/app2;

        # Log all Shiny output to files in this directory
        log_dir /var/log/shiny-server/app2;

        # When a user visits the base URL rather than a particular application,
        # an index of the applications available in this directory will be shown.
        directory_index off;
    };

}
