5.13.3 Configuring R Interpreter

1. Configure Rserve
   nano /scratch/software/R/Rserve.conf (sample file)
   >
   auth required
   plaintext disabled
   pwdfile /scratch/software/R/creds/Rserve.pwd
   remote enable
   switch.qap.tls enable
   tls.port 6311
   qap disable
   interactive no
   rsa.key /scratch/software/R/creds/server.key
   tls.key /scratch/software/R/creds/server.key
   tls.cert /scratch/software/R/creds/server.crt
2. 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.
3. 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
4. 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
