How to Set-Up Shiny Server on Ubuntu
Shiny is an R package that allows Linux users to convert R code into an interactive webpage and documents online. You can take your shiny apps and share them in your organisation or the world. This article explains about how to set up shiny server on Ubuntu.
Installing Shiny Server on Ubuntu
Before installing Shiny server, we need to install the shiny R package. To install R packages, use the following command –
$ sudo apt-get install r-base
The sample output should be like this -
Reading package lists... Done Building dependency tree Reading state information... Done The following packages were automatically installed and are no longer required: apport-hooks-elementary contractor javascript-common libgda-5.0-4 libgda-5.0-common libgranite-common libgranite3 libgsignon-glib1 libindicate5 libjs-jquery libnoise-core0 libtagc0 mysql-server-5.7 mysql-server-core-5.7 Use 'sudo apt autoremove' to remove them. The following additional packages will be installed: bzip2-doc cdbs debhelper dh-strip-nondeterminism dh-translations gfortran gfortran-5 intltool libblas-common libblas-dev libblas3 libbz2-dev libfile-stripnondeterminism-perl libgfortran-5-dev libgfortran3 liblapack-dev liblapack3 liblzma-dev liblzma5 libmail-sendmail-perl libncurses5-dev libpcre3-dev libpcre32-3 libpcrecpp0v5 libpng12-dev libreadline-dev libreadline6-dev libsys-hostname-long-perl libtinfo-dev po-debconf python-scour python-six r-base-core r-base-dev r-base-html r-cran-boot r-cran-class r-cran-cluster r-cran-codetools r-cran-foreign r-cran-kernsmooth r-cran-lattice r-cran-mass r-cran-matrix r-cran-mgcv r-cran-nlme r-cran-nnet r-cran-rpart r-cran-spatial r-cran-survival r-doc-html r-recommended .......................................................................
We’re going to install Shiny server with the GDebi tool. To install GDebi, use the following command –
$ sudo apt-get install gdebi-core
The sample output should be like this –
Reading package lists... Done Building dependency tree Reading state information... Done The following packages were automatically installed and are no longer required: apport-hooks-elementary contractor javascript-common libgda-5.0-4 libgda-5.0-common libgranite-common libgranite3 libgsignon-glib1 libindicate5 libjs-jquery libnoise-core0 libtagc0 mysql-server-5.7 mysql-server-core-5.7 Use 'sudo apt autoremove' to remove them. The following NEW packages will be installed: gdebi-core 0 upgraded, 1 newly installed, 0 to remove and 180 not upgraded. Need to get 9,716 B of archives. After this operation, 135 kB of additional disk space will be used.

To download Shiny server, use the following command –
$ wget https://download3.rstudio.org/ubuntu-12.04/x86_64/shiny-server-1.4.2.786-amd64.deb
The sample output should be like this –

Now use GDebi to install the file that was downloaded using the following command –
$ sudo gdebi shiny-server-1.4.2.786-amd64.deb
The sample output should be like this –

Hint: Some lines were ellipsized, use -l to show in full.
Shiny Server should now be installed and running on port 3838. You should be able to see a default welcome screen at http://your_server_ip:3838/. The sample output should be like this –
Hosting Interactive R Markdown Documents
At this point you should have a working Shiny Server that can host Shiny applications, but it cannot yet host interactive R markdown documents because the rmarkdown R package isn’t installed. Shiny Server comes with a sample interactive document that is available at
Shiny Server comes with a sample interactive document that is available at http://your_server_ip:3838/sample-apps/rmd/. If you go to that URL right now, you will see an error.
To fix the above problem, use the following command-
$ sudo su - -c "R -e \"install.packages('rmarkdown', repos='http://cran.rstudio.com/')\""The sample output should be like this –

Now, Shiny server is set up to run interactive R markdown documents as well as Shiny applications. To verify how interactive documents work, go to http://your_server_ip:3838/sample-apps/rmd/.
You now have a functioning Shiny Server that can host Shiny applications or interactive documents. The configuration file for Shiny Server is at /etc/shiny-server/shiny-server.conf. By default it is configured to serve applications in the /srv/shiny-server/ directory. This means that any Shiny application that is placed at /srv/shiny-server/app_name will be available to the public at http://your_server_ip:3838/app_name/.
After this article, you will be able to understand – How To Set Up Shiny Server on Ubuntu. In our next articles, we will come up with more Linux based tricks and tips. Keep reading!
