Open Source Shiny Server는 한 서버에 여러개의 Shiny application을 hosting할수 있는 platform을 제공한다.
building on non-supported distributions , Administrator’s Guide 을 참조

설치 전 확인 

1. R 설치 확인

R는 당연히 설치되어 있어야 한다. 

⇒  R --version

2. Shiny package 설치

(Shiny 서버 설치전) R에 Shiny 팩키지 설치

Ubuntu

방법1

sudo R
> .libPaths()
[1] "/usr/local/lib/R/site-library" 
[2] "/usr/lib/R/site-library"      
[3] "/usr/lib/R/library"

> install.packages('shiny', lib=.libPaths()[1])

방법2

sudo su - -c "R -e \"install.packages('shiny', repos='https://cran.rstudio.com/', lib=.libPaths()[3])\""

Installing package into ‘/usr/lib/R/library’
(as ‘lib’ is unspecified)
also installing the dependencies ‘Rcpp’, ‘httpuv’, ‘mime’, ‘jsonlite’, ‘xtable’, 
‘digest’, ‘htmltools’, ‘R6’, ‘sourcetools’

 방법3 (local)

$ sudo su - -c "R -e \"install.packages('shiny', repos='https://cran.rstudio.com/')\""

 cf. HTTPS에 문제가 있는 경우 CRAN mirror를 사용

$ sudo su - -c "R -e \"install.packages('shiny', repos='http://cran.nexr.com/')\""

 확인

3. rMarkdown package 설치(option)

$ sudo su - -c "R -e \"install.packages('rmarkdown', repos='http://cran.nexr.com/')\""

다운로드 

deb파일 실행으로 위해 gdebi-core를 먼저 설치하고,

$ sudo apt-get install gdebi-core

보안으로 인해 다운이 안될 경우, -no-check-certificate 옵션을 맨뒤 사용.

$ sudo wget https://download3.rstudio.org/ubuntu-12.04/x86_64/shiny-server-1.5.4.869-amd64.deb

설치

다운받은 deb파일 실행하여 설치

Install Dependencies and Packages Needed by Shiny Server

We’re going to need the devtools package,
which means we need to install the libraries upon which it depends first (libcurl and libxml2):

$ sudo apt-get -y build-dep libcurl4-gnutls-dev
$ sudo apt-get -y install libcurl4-gnutls-dev
$ sudo apt-get -y build-dep libxml2-dev
$ sudo apt-get -y install libxml2-dev

Shiny server 관리

systemctl stop shiny-server.service 2>/dev/null 
systemctl start shiny-server.service
