Installing R on CentOS/RedHat Linux

by  / in , , , , /





For using the RStudio in Linux, we need to setup some config file.

First, create these 2 config file
$ touch /etc/rstudio/rserver.conf /etc/rstudio/rsession.conf

Edit /etc/rstudio/rserver.conf for port change and home address
$ vi /etc/rstudio/rserver.conf 

#default port is 8787

www-port=80
www-address=127.0.0.1

Note that after editing the /etc/rstudio/rserver.conf file you should always restart the server to apply your changes (and validate that your configuration entries were valid). You can do this by entering the following command:

$ sudo rstudio-server restart

After restarting the RStudio server, you can access RStudio tool in your browser by below URL

http://127.0.0.1:80/

generic URL -
http://<RStudio home Address>:<Port>
