网页上闪亮的服务器错误：发生错误应用程序无法启动。发生 错误 应用程序未能启动：初始化

我想设置[R闪亮的服务器上我的亚马逊AWS的Linux EC2实例和正在以下错误在应用程序退出。网页上闪亮的服务器错误：发生错误应用程序无法启动。发生 错误 应用程序未能启动：初始化

应用程序在初始化期间退出。

我做了须藤闪亮的服务器来看看发生了什么，看到了错误EADDRINUSE：

$ sudo shiny-server 
[2017-01-29 13:21:22.724] [INFO] shiny-server - Shiny Server  v1.5.1.834 (Node.js v6.9.1) 
[2017-01-29 13:21:22.728] [INFO] shiny-server - Using config file "/etc/shiny-server/shiny-server.conf" 
[2017-01-29 13:21:22.764] [INFO] shiny-server - Starting listener on 0.0.0.0:80

[2017-01-29 13:21:22.771] [INFO] shiny-server - Shutting down worker processes

我核实，有光泽，rmarkdown和，闪亮的服务器和R正确安装在我的实例：

R --version

我还检查了我的EC2实例的网络连接：

$ sudo netstat --tcp -nlpa | grep 80 
tcp  0  0 0.0.0.0:80     0.0.0.0:*     LISTEN  1875/shiny-server

我的EC2实例的网络安全组：

$ aws ec2 describe-security-groups --group-name launch-wizard-7 
{ 
"SecurityGroups": [ 
    { 
     "IpPermissionsEgress": [ 
      { 
       "IpProtocol": "-1", 
       "PrefixListIds": [], 
       "IpRanges": [ 
        { 
         "CidrIp": "0.0.0.0/0" 
        } 
       ], 
       "UserIdGroupPairs": [], 
       "Ipv6Ranges": [] 
      } 
     ], 
     "Description": "launch-wizard-7 created 2017-01-28T14:22:51.817-05:00",

       "FromPort": 80, 
       "IpRanges": [ 
        { 
         "CidrIp": "0.0.0.0/0" 
        } 
       ], 
       "ToPort": 80, 
       "IpProtocol": "tcp", 
       "UserIdGroupPairs": [], 
       "Ipv6Ranges": [] 
      },

（还有另一个条目但SSH到我自己的机器，所以我不会把这些信息）

，这里是从我的光泽，server.conf文件/etc/shiny-server/shiny-server.conf

$ cat /etc/shiny-server/shiny-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; 
} 
}

任何帮助将非常感激。我试图让AWS监听所有IP地址和闪亮服务器的端口80的请求，因为我想这两个服务都不应该听同一个端口，但这样做不起作用。我只是想部署发光服务器附带的示例应用程序。

我也徘徊，如果我的AWS安全组应该允许所有IP和闪亮服务器的端口80的入站流量侦听端口3838或其他方式。 – jonathan1987
