Configuring R Interpreter

Configure Rserve

pwdfile /scratch/software/R/creds/Rserve.pwd

remote enable

rsa.key /scratch/software/R/creds/server.key

tls.key /scratch/software/R/creds/server.key

tls.cert /scratch/software/R/creds/server.crt

password file Rserve.pwd:

oml
                    $5baa61e4c9b93f3f0682250b6cf8331b7ee68fd8

The file contains one line per user, where the first part is the username, and the second part is the password.

The password can either be plain text or a MD5/SHA1 hash. In this example the password `password` is hashed with SHA1.

If you use hashed passwords, the password string needs to start with a `$` sign.

SSL Key:

openssl genrsa -out server.key 2048

openssl req -new -key server.key -out server.csr # password
                        1234

openssl x509 -req -days 365 -in server.csr -signkey server.key -out
                        server.crt

Creating Keystore:

keytool -import -alias <keystore-alias> -file
                        <path-to-server.crt>/server.crt -keystore
                        <output-path-to-keystore/rinterpreterkeystore -storepass
                        <keystore-secret> -noprompt

eg. keytool -import -alias rserve -file
                        /scratch/software/R/creds/server.crt -keystore
                        /scratch/software/R/creds/rinterpreterkeystore -storepass changeit
                        -noprompt

Steps to enable TLS during R Interpreter Installation

Steps to enable TLS during R Interpreter Installation:

Download Rserve_1.8-10.tar.gz from this link: https://cran.r-project.org/src/contrib/Archive/Rserve/
Install openssl-devel - [yum install openssl-devel]
Execute below cmd:
R CMD INSTALL --configure-args="--with-ssl-headers=/usr/include --with-ssl-libraries=/usr/lib64" Rserve_1.8-10.tar.gz

The below steps can be executed from R session to check that Rserve configuration is working before starting the services:
Start R from Terminal/Putty and execute the below commands:
- library(Rserve)
- Rserve(args="--RS-conf <Rserve.conf file location including file name> --no-save")
