NginX serer는 Rstudio server와 Shiny server의 Proxy server역할을 하여,
각 서버의 결과물을 외부에서 http server (web page)를 통해 접속함.

설치방법
- nginx.service – A high performance web server and a reverse proxy server
http://onesixx.com/install-nginx-ubuntu/ - rstudio-server.service – RStudio Server\\\\\\\\\\\\\\\\\\\\
http://onesixx.com/install-rstudio-server-ubuntu/
shiny-server.service – ShinyServer
http://onesixx.com/install-shiny-server-ubuntu/
1. 설정파일 수정
– 모든 서버 shut down
sudo systemctl stop nginx sudo systemctl stop rstudio-server sudo systemctl stop shiny-server
– Nginx의 default.conf 수정
sudo vi /etc/nginx/sites-available/default
아래내용 추가
location /rstudio/ {
rewrite ^/rstudio/(.*)$ /$1 break;
proxy_set_header X-RSC-Request $scheme://$host:$server_port$request_uri;
proxy_pass http://localhost:8787;
proxy_redirect / /rstudio/;
proxy_set_header Upgrade $http_upgrade;
#proxy_set_header Connection $connection_upgrade;
proxy_http_version 1.1;
}
location /shiny/ {
rewrite ^/shiny/(.*)$ /$1 break;
proxy_pass http://localhost:3838;
proxy_redirect http://localhost:3838/ $scheme://$host/shiny/;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
#proxy_set_header Connection $connection_upgrade;
proxy_read_timeout 20d;
auth_basic "Username and Password are required";
auth_basic_user_file /etc/nginx/.htpasswd;
}
* shiny아래 auth_basic은 로그인 창을 위한 설정
– RStudio server 의 Configuration 수정
/etc/rstudio/rserver.conf 없으면 만든다.
Proxy 서버역할을 하는 NginX를 통해서만 접근가능하도록 변경. RStudio Server 와 NginX server가 한 머신에서 실행되고 있다면,
RStudior가 0.0.0.0 (all remote clients) 에서 127.0.0.1 (only the localhost)를 Listen할수 있도록 port를 변경한다.
www-address=127.0.0.1
– Shiny server 의 Configuration 수정
/etc/shiny-server/shiny-server.conf
Proxy 서버역할을 하는 NginX를 통해서만 접근가능하도록 변경.
listen 3838 127.0.0.1
5. 서비스 시작
Restart Service
sudo systemctl start rstudio-server sudo systemctl start shiny-server sudo systemctl start nginx
6. 확인
xxx.xxx.xxx.xxx:8787 이나 localhost:3838 로는 접속이 안되고, host_ip/rstudio나 host_ip/shiny로만 접속된다.

접근가능한 폴더 추가
위 default파일에서 서버 Root는 아래와 같고,
root /var/www/html;
해당 폴더에 링크를 추가하여, 원하는 폴더를 추가한다.
sudo ln -s /Users/onesixx/Dropbox/RHome/lecture /var/www/html/lecture
결과 확인
⇒ pwd /var/www/html ⇒ ll -rw-r--r-- 1 root root 612 4월 17 16:30 index.nginx-debian.html lrwxrwxrwx 1 root root 37 4월 20 09:28 lecture -> /Users/onesixx/Dropbox/RHome/lecture lrwxrwxrwx 1 root root 29 5월 4 16:34 rhome -> /Users/onesixx/Dropbox/RHome
