% Time-stamp: <2019-04-02 00:06:10>

  1. Either install the package using git clone or download and unzip
  2. Download and unzip in the directory of the project. This will unpack the databases in the databases subfolder.`

Shiny server

Here, wes explain how to deploy a shiny server on a Ubuntu 18.04 Linux server, and how to install the openlexicon databases on it.

The following commands must be executed on the computer that will be used as the server.

Installation of R

sudo apt install -y apt-transport-https software-properties-common
sudo apt install -y build-essential

sudo apt-key adv --keyserver --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9

sudo add-apt-repository 'deb bionic-cran35/'

sudo apt update
sudo apt install -y r-base

Installaion of RShiny and Shiny server

Following the instructions at

sudo su - -c "R -e \"install.packages('shiny', repos='')\""
sudo su - -c "R -e \"install.packages('DT','rmarkdown')\""

sudo apt-get install -y gdebi-core
sudo wget
sudo gdebi shiny-server-

You can run the server by accessing http://servername:3838 where servername it the name or the IP address of your server. For a local installation, it would be localhost.

If you want to setup the server main page (http://servername) to point on rshiny, you need to edit /etc/shiny-server/shiny-server.conf to modify the port from 3838 to 80

nano /etc/shiny-server/shiny-server.conf  # change port from 3838 to 80
systemctl restart shiny-server

Add the openlexicon shiny apps to the shiny-server


git clone shiny-server
cd shiny-server/

Edit /etc/shiny-server/shiny-server.conf:

server {
listen 3838;

# For root shiny server (in shinyapps user home folder)
location / {

# The shiny-server process would run by user `chrplr`
run_as chrplr;

# Save logs here
log_dir /var/log/shiny-server;

# Path to shiny server for separate apps
site_dir /home/chrplr/shiny-server;

# List contents of a (non-Shiny-App) directory when clients visit corresponding URIs
directory_index on;

# Allow users to host their own apps in `~/ShinyApps`
location /users {
  run_as :HOME_USER:;

proxying shiny server through nginx

If you use a web server like apache2 or nginx, you can configure them to proxy the shiny-server. For nginx, for example, I added the following inside the http directive in /etc/nginx/nginx.conf

 map $http_upgrade $connection_upgrade {
     default upgrade;
     ''      close;

  server {
     listen 80;

     rewrite ^/shiny$ $scheme://$http_host/shiny/ permanent;

     root /var/www/html;
     autoindex on;
     index index.html index.htm index.php;
     location /shiny/ {
         rewrite ^/shiny/(.*)$ /$1 break;
         proxy_pass http://localhost:3838;
         proxy_redirect / $scheme://$http_host/shiny/;
         proxy_http_version 1.1;
         proxy_set_header Upgrade $http_upgrade;
         proxy_set_header Connection $connection_upgrade;
         proxy_read_timeout 20d;
         proxy_buffering off;

     location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;

     location ~ /\.ht {
            deny all;

     location / {
         root /var/www/html;
         autoindex on;
