Installing Rserve

Following are the steps that were taken to install Rserve for an application. I am working on CentOS release 6.5 (Final)

The two are available at: http://rforge.net/Rserve/ and http://rforge.net/FastRWeb/

All the steps below were performed as root unless specified otherwise.

Rserve

1. Check the version of R and if it is not installed install R.  You may have to install new repository EPEL i.e. Extra Packages for Enterprise Linux.  Here is a page describing that http://www.tecmint.com/how-to-enable-epel-repository-for-rhel-centos-6-5/

yum install R

Now I have R version 3.1.1 (2014-07-10) working

2. Start R and type

install.packages("Rserve")

Once install process is done you can check the instal files using

ls -al /usr/lib64/R/library/Rserve/

3.  Created a file /etc/Rserv.conf with following content to run the R process as apache

uid apache
gid apache
workdir /tmp/Rserv
fileio enable
port 6311
maxinbuf 262144

4. Start Rserve and check if running then stop it

R CMD Rserve --gui-none --no-save
ps -eaf | grep Rserve

killall Rserve

5. Add a startup script by creating a file /etc/init.d/Rserve and adding the content. Thanks to (http://paranumeral.blogspot.com/2013/03/a-basic-etcinitdrserve-start-rserve-at.html) on which I have used most of the content.

RSERVE=/usr/lib64/R/bin/Rserve
. /etc/rc.d/init.d/functions
test -f /etc/Rserv.conf
export R_HOME=/usr/lib64/R
RETVAL=0
case "$1" in
   start)
      echo -n "Starting Rserve: "
      [ -f $RSERVE ] || exit 1
      $RSERVE --gui-none --no-save
      RETVAL=$?
      echo
      [ $RETVAL -eq 0 ] && touch /var/lock/subsys/rserve
      ;;
  stop)
      echo -n "Shutting down RServe: "
      killproc $RSERVE
      RETVAL=$?
      echo
      [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/rserve
      ;;
  restart|reload)
      $0 stop
      $0 start
      RETVAL=$?
      ;;
  status)
      status $RSERVE
      RETVAL=$?
      ;;
  *)
      echo "Usage: $0 {start|stop|restart|status}"
      exit 1
esac
exit $RETVAL

6. Change permissions of auto start script, test start and stopping:

chmod 755 /etc/init.d/Rserve 
service Rserve start
service Rserve stop

7. Finally configure to start with reboot of machine

chkconfig --level 2345 Rserve on
