Follow the steps in Section 5.3, “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
