ubuntu - 运行 Shiny 服务器时出错

Question

我尝试在 Ubuntu 中从终端运行 Shiny 的服务器，但我收到此错误:

nik@nik-VirtualBox:~$ shiny-server
[2017-02-13 10:42:28.353] [INFO] shiny-server - Shiny Server v1.5.1.834 (Node.js v6.9.1)

[2017-02-13 10:42:28.510] [INFO] shiny-server - Shutting down worker processes

如何在 shiny-server 中运行应用程序？

新错误:

nik@nik-VirtualBox:~$ sudo shiny-server
[sudo] password for nik:

Shiny 服务器有一个配置文件。默认用户名是 shiny。您的系统中没有用户 shiny，因此服务器拒绝启动。我通过以下方式解决了这个问题。

sudo nano /etc/shiny-server/shiny-server.conf

有一行:

run_as shiny;

将 shiny 更改为合法的用户名，然后重新启动 shiny 服务器:

sudo systemctl restart shiny-server
