r 闪亮的服务器是运行，但该应用程序无法运行

Question

我们在 linux ubuntu 上构建了 shiny-server，我检查了状态和 shiny-server.conf，两者似乎都可以，但无法运行 app，请看下图： 1.闪亮服务器状态：

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

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;
  }
}

但是，当我将 server.R 和 UI.R 文件放在 srv/shiny-server 下，然后将运行放在 URL 下时，它是徒劳的，并显示 "Not found"。

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

Answer 1

下面的代码显示了创建的所有应用程序文件夹，您可以在其下创建各种应用程序，如 app1、app2..等

下方将显示

下的所有应用

http://<my_server>:3838/allappfolders

下面的 app1 将加载 ui.R 和 server.R

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

完全确认。代码如下：

# 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;
    };

}

Answer 2

3838 端口 IPTABLES 问题：我在新的 LINUX CENTOS 系统上安装了 SShiny Server。一切都很好，但示例应用程序未加载。幸运的是，我的同事是一个 LINUX NERD，并迅速检查了端口 IPTABLE 条目。他将其设置为 OFF 和 EUREKA！我的示例应用已经启动运行。当系统连接到互联网时，只需安装 rmarkdown 包。
