1. shiny server簡介
shiny-server是一種可用把R 語言以web形式展示的服務,下面就講講如何在自己的服務器上構建Shiny Server。下一篇主要介紹如何集成sparkR后展示在web界面上
環境:ubuntu14.04
下載:shiny-server的地址
2. 安裝步驟
2.1 安裝libpng,x11相關支持包
由於ubuntu默認是不支持png 以及X11(redhat,centos也會有同樣的問題)
所以安裝R語言前需要安裝libpng,x11相關包,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 安裝R語言 驗證X11 ,libpng支持
bonnie@bonnie0:~$ sudo apt-get install r-base
在命令行輸入R進入R語言shell
bonnie@bonnie0: R
R version 3.0.2 (2013-09-25) -- "Frisbee Sailing"

PS:如果你不是在ubuntu本機操作登陸,而是遠程通過ssh登錄時,ssh username@ip地址 要加 -X, 否則X11會顯示FALSE
2.2 在R中安裝shiny模塊
在R命令行中運行 install.packages("shiny")
> install.packages("shiny")
運行成功后(ctl + C)退出R界面
2.3 安裝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 啟動與關閉 shiny-server
2.5 登陸web界面查看運行情況
http://10.211.55.16:3838/ 默認端口時3838,可以在配置文件(/etc/shiny-server/shiny-server.conf)中修改
