Question

我试图在脱机的Debian VM上托管闪亮的应用程序。所以，首先，我在VM上安装带有apt-get的R-version 3.1.1：

$ sudo apt-get update
$ sudo apt-get install r-base
$ sudo apt-get install r-base-dev

然后，我将“闪亮”软件包的所有tar.gz文件（包括所有依赖项）从我的本地scp到VM并使用“R CMD ...”成功安装它们。之后，我运行以下命令来安装“gdebi”并用它来为闪亮的服务器安装“shiny-server-1.3.0.403-amd64.deb”。

$ sudo apt-get install gdebi-core
$ sudo gdebi shiny-server-1.3.0.403-amd64.deb

它在第一次返回错误，表明缺少依赖项：

Reading package lists... Done
Building dependency tree        
Reading state information... Done
Building data structures... Done 
Building data structures... Done 
This package is uninstallable
Dependency is not satisfiable: libssl0.9.8

然后，我按照另一篇文章将以下行添加到“etc / apt / sources.list”文件中，然后使用“apt-get”安装缺少的依赖项：

 deb http://security.ubuntu.com/ubuntu lucid-security main

 $ sudo apt-get install libssl0.9.8

看起来很有效，我安装了“shiny-server-1.3.0.403-amd64.deb”：

$ sudo gdebi shiny-server-1.3.0.403-amd64.deb

Shiny Server
Shiny Server is a server program from RStudio, Inc. that makes Shiny applications available over the web. Shiny is a web application framework for the R statistical computation language.

然而，当我试图从终端“停止/启动”闪亮的服务器时，cli无法识别命令：

$ sudo stop shiny-server
sudo: stop: command not found

我想知道我是否正确安装了服务器？我怎样才能“启动/停止”闪亮的服务器？

Answer 1

我在Debian Wheezy上一直使用闪亮服务器，但在升级到Debian Jessie时切换到自编译，因为这是每个RStudio文档推荐的路由。

要回答您的问题，使用init.d脚本管理shiny-server。要启动服务器，您应该以root身份运行/etc/init.d/shiny-server start或service shiny-server start（sudo）。

Answer 2

这不是一个有光泽的问题，只是你错过了命令，stop是命令的一个选项service

您应该使用：

sudo service start shiny-server

开始吧

sudo service stop shiny-server

停止它
