shiny server SparkR web展示界面(一)
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
bonnie@bonnie0:~$ 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
bonnie@bonnie0:~$ 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
bonnie@bonnie0:~$ sudo apt-get install r-base
在命令行输入R进入R语言shell
bonnie@bonnie0: 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 username@ip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
bonnie@bonnie0:~$ sudo apt-get install gdebi-core
bonnie@bonnie0:~$ wget https://download2.rstudio.org/rstudio-server-1.0.44-amd64.deb
bonnie@bonnie0:~$ sudo gdebi rstudio-server-1.0.44-amd64.deb
2.4 启动与关闭 shiny-server
2.5 登陆web界面查看运行情况
http://10.211.55.16:3838/ 默认端口时3838,可以在配置文件(/etc/shiny-server/shiny-server.conf)中修改
