Install RServe

Download the RServe service from the following RServe web site:
http://www.rforge.net/Rserve/files/

Refer to the installation documentation at http://www.rforge.net/Rserve/doc.html for detailed information about how to install the service.

Note: RServe and the DSB component must be installed on the same server. Also, do not install RServe from CRAN by using the R install.packages command, because the version on CRAN often is out of date.

To install RServe:

1. Download the Rserve_0.5-<version>.tar.gz package, place it in the current R directory and execute the following command as the root user:
   R CMD INSTALL Rserve_0.5-X.tar.gz
2. Create a configuration file to define the following:
   • Assign the directory in which RServe will store temporary files.
   • Assign the communication port on which Rserve will accept connections.
   • Assign the user account under which the daemon will run. 

     Make sure that the user account has write permission in both the temp directory and the DSB temp directory tree, /tmp/VDC.
   • Choose the account password.

   See the example RServe /etc/Rserv.conf configuration file.
   The file /etc/Rserv.pwd stores the RServe access username and password. Note that these do not constitute a UNIX login username and password; these credentials are used by RServe only and cannot be used to open a shell on the system if compromised. An example /etc/Rserv.pwd file is:
   <account> <password>
   For more information on RServe configuration parameters, refer to the RServe documentation at http://www.rforge.net/Rserve/doc.html.

3. Start the RServe daemon. 
Type the following:
   R CMD Rserve
4. Create a startup file to make sure that RServe starts at boot time.

workdir /tmp/Rserv
pwdfile /etc/Rserv.pwd

plaintext disable
fileio enable
