篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了shiny server SparkR web展示界面相关的知识，希望对你有一定的参考价值。

1. shiny server简介

shiny－server是一种可用把R 语言以web形式展示的服务，下面就讲讲如何在自己的服务器上构建Shiny Server。下一篇主要介绍如何集成sparkR后展示在web界面上

环境：ubuntu14.04

下载：shiny－server的地址

2. 安装步骤

2.1 安装libpng，x11相关支持包

由于ubuntu默认是不支持png 以及X11（redhat，centos也会有同样的问题）

所以安装R语言前需要安装libpng，x11相关包，命令如下

[email protected]:~$ sudo apt-get install build-essential gcc g++ autoconf libiconv-hook-dev libmcrypt-dev libxml2-dev libmysqlclient-dev libcurl4-openssl-dev libjpeg8-dev libpng12-dev libfreetype6-dev

[email protected]:~$ sudo apt-get install libX11-dev libXext-dev libXtst-dev libXrender-dev libxmu-dev libxmuu-dev

2.2 安装R语言验证X11 ，libpng支持

[email protected]:~$ sudo apt-get install r-base

在命令行输入R进入R语言shell

[email protected]: R

    TRUE     TRUE     TRUE     TRUE     TRUE     TRUE     TRUE

PS：如果你不是在ubuntu本机操作登陆，而是远程通过ssh登录时，ssh [email protected]地址要加 -X, 否则X11会显示FALSE

2.2 在R中安装shiny模块

在R命令行中运行 install.packages("shiny")

> install.packages("shiny")

运行成功后（ctl ＋ C）退出R界面

2.3 安装shiny-server

[email protected]:~$ sudo apt-get install gdebi-core [email protected]:~$ wget https://download2.rstudio.org/rstudio-server-1.0.44-amd64.deb [email protected]:~$ sudo gdebi rstudio-server-1.0.44-amd64.deb
