Follow the steps in Section 2.6.3, “Creating Suitable Certificates” to create JGroups and TLS certificates.
Update your configuration to specify these certificates and the keystore password:
shell> tools/tpm configure SERVICE
\
--java-tls-keystore-path=/etc/tungsten/tls.jks \
--java-jgroups-keystore-path=/etc/tungsten/jgroups.jceks \
--java-keystore-password=mykeystorepass
