In the last four months, I worked to develop a web application with shiny server to analyze with the Kernel density estimation the density of TV viewers in Tunisia during the prime time.

I will describle below the steps of the installation that will help you if you need to use CentOS 32 bits or 64 bits.

I’m a root user !

Through my experience , I can advise you to install these development libraries first

1
2
     yum install libssl-dev
     yum install openssl-devel

Install Node.js from the official web site See related article here

  cd /opt
  wget http://nodejs.org/dist/latest/node-v0.10.5.tar.gz
  tar -xvf node-v0.10.5.tar.gz
  cd node-v0.10.5
  ./configure && make && sudo make install

Now, you can install R but before, this you make sure to install EPEL repos

  wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
  sudo rpm -Uvh remi-release-6*.rpm epel-release-6*.rpm
  ls -1 /etc/yum.repos.d/epel* /etc/yum.repos.d/remi.repo
  /etc/yum.repos.d/epel.repo
  /etc/yum.repos.d/epel-testing.repo
  /etc/yum.repos.d/remi.repo

with this command you can see all installed repos and then change enabled from 1 to 0

1
     vi /etc/yum.repos.d/

Then you are ready to install R and Rstudio server.

cd /tmp/
wget http://download2.rstudio.org/rstudio-server-0.97
.449-x86_64.rpm
yum install --nogpgcheck rstudio-server-0.97.449-x86_64.rpm

to Install npm

1
yum install npm

Install Shiny server with npm command

1
npm install -g shiny-server

After finishing the installation , you can configure the starting method of R studio

1
p –R config/upstart/shiny-server.conf /etc/init/

You are ready to start shiny server now !

1
start shiny-server

Finally, I installed packages using the terminal not RStudio server because it’s simplify the setup of UNIX File Permissions,but you can use as well the Rstudio interface.

1
u - -c "R -e \"install.packages('dbconnect',repos='http://cran.r-project.org/')\""

That’s it ! please let me know if it was helpful for you .
