Unable to deploy Shiny application on Shiny Server in Linux VM - r

Question

I have been trying to deploy my shiny application in shiny server which i have installed on Linux VM (RHEL 6.5, 64 bit) by following the instructions given in this site
The server is started successfully but i get the following when i try to access the sample application provided as a part of the shiny server.
Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared object '/usr/lib64/R/library/Rcpp/libs/Rcpp.so':
/usr/lib64/R/library/Rcpp/libs/Rcpp.so: invalid ELF header
In addition: Warning message:
package ‘shiny’ was built under R version 3.3.0
Error: package or namespace load failed for ‘shiny’ Execution halted
I installed all the required packages without any error still i got this exception when i tried to access the sample application.
The following are the steps i followed to install shiny server.
Installed R. In my office EPEL repository is blocked since it is maintained by a third party organization. So I downloaded the rpm file for R from EPEL website and installed the same using the rpm command.
Next i downloaded the shiny package from the CRAN repository and installed the same using the following command
R CMD INSTALL shiny_0.13.2.tgz
Finally i downloaded and installed the shiny server RPM file.
The server was successfully installed and started without any errors, yet i get the above error when trying to access the application deployed in the server.
I googled a lot for this error but could not find much. Has anybody else faced this issue? Could someone help me out with this?

Answer 1

I found out the issue. I installed all the packages as root user but shiny server runs under a different username "shiny". In order to solve this I started an R session using the following command
sudo R
Then I installed the packages using their source, as my LINUX VM (office machine)did not have internet access. I used the following command for installing the packages from the source. First we need to untar the source and then run the following command.
require(devtools)
install('path-to-the-untared-folder')
