Question

我们已经在linux ubuntu上构建了闪亮的服务器，我检查了状态和shiny-server.conf，两者似乎没问题，但是无法运行应用程序，请看如下： 1.闪亮的服务器状态：

  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，然后运行该网址时，它是徒劳的并显示“未找到”。

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

Answer 1

下面的代码显示了创建的allappfolders，您可以在其下创建app1，app2..etc等各种应用。

下面将显示

下的所有应用

http://<my_server>:3838/allappfolders

app1下方将加载ui.R和server.R

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

完整的conf。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SHiny Server。一切都很好，但示例应用程序没有加载。幸运的是，我的同事是一个LINUX NERD并快速检查端口IPTABLE条目。他把它设置为OFF和EUREKA！我的示例应用程序启动并运行。当系统连接到互联网时，只需安装rmarkdown软件包。

r闪亮的服务器正在运行，但该应用程序无法运行
