Question

我在Ubuntu 16.04.1上安装了闪亮服务器，根据控制台输出，它处于活动状态并正在运行：

    systemctl status shiny-server
● shiny-server.service - ShinyServer
   Loaded: loaded (/etc/systemd/system/shiny-server.service; enabled; vendor preset: enabled)
   Active: active (running) since Wed 2016-08-24 18:17:09 CEST; 15h ago
  Process: 13175 ExecStartPost=/bin/sleep 3 (code=exited, status=0/SUCCESS)
 Main PID: 13179 (shiny-server)
    Tasks: 7
   Memory: 28.5M
      CPU: 158ms
   CGroup: /system.slice/shiny-server.service
           ├─13174 /bin/bash -c /opt/shiny-server/bin/shiny-server --pidfile=/var/run/shiny-server.p
           └─13179 /opt/shiny-server/ext/node/bin/shiny-server /opt/shiny-server/lib/main.js --pidfi
lines 1-11/11 (END)

然后我按照安装指南中的说明打开了端口3838：

netstat -ntlp | grep LISTEN
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN      -
tcp        0      0 0.0.0.0:3838            0.0.0.0:*               LISTEN      -
tcp6       0      0 :::80                   :::*                    LISTEN      -
tcp6       0      0 :::22                   :::*                    LISTEN      -

sudo ufw status
Status: active

80/tcp                     ALLOW       Anywhere
22/tcp (v6)                ALLOW       Anywhere (v6)
3838/tcp (v6)              ALLOW       Anywhere (v6)
80/tcp (v6)                ALLOW       Anywhere (v6)

然而，如果我尝试通过浏览器中的端口3838访问我的服务器，我不会从服务器获得任何响应，并且该站点保持空白并最终超时。

我可能缺少什么想法？

显然我的服务器上的端口3838存在一些问题。虽然上面的控制台输出声明它已打开并列为＆＃34; LISTEN＆＃34;但它仍然无法正常工作。当我将配置文件（/etc/shiny-server/shiny-server.conf）中的shiny-server的默认端口更改为80时，它突然工作了：

    # Define a top-level server which will listen on a port
    server {
       # Instruct this server to listen on port 3838
       listen 80;
       ...

闪亮服务器安装：服务器在端口3838上没有响应
