Follow the steps in Section 5.3, “Creating Suitable Certificates” to create JGroups and TLS certificates.
Transfer the generated certificates to the same path on all hosts.
Update your configuration to specify these certificates and the keystore password:
java-tls-keystore-path=/etc/tungsten/secure/tungsten_tls_keystore.jks
java-jgroups-keystore-path=/etc/tungsten/secure/tungsten_jgroups_keystore.jceks
java-keystore-password=mykeystorepass
