r - 在 Debian VM 上安装 Shiny 的服务器

Question

我试图在离线 Debian VM 上托管 Shiny 的应用程序。所以，首先，我在虚拟机上安装带有 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，我从本地将“ Shiny ”包的所有 tar.gz 文件(包括所有依赖项)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”并使用它为 Shiny 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

它在第一时间返回错误，表明缺少依赖项:

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

它似乎有效，我安装了“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.
Do you want to install the software package? [y/N]:y

Adding LANG to /etc/init.d/shiny-server, setting to en_US.UTF-8

然而，当我尝试从终端“停止/启动” Shiny 的服务器时，cli 无法识别该命令:

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

我想知道我是否正确安装了服务器？如何“启动/停止” Shiny 服务器？

Answer 1

我一直在 Debian Wheezy 上以这种方式使用 shiny-server，但是当我升级到 Debian Jessie 时切换到自编译，因为这是每个 RStudio 文档的推荐路线。

为了回答您的问题，shiny-server 使用 init.d 脚本进行管理。要启动服务器，您应该运行 /etc/init.d/shiny-server start或 service shiny-server start作为根 (sudo)。
