Single Node Setup Instructions
1. Ensure you have the syndeia-cloud-3.56_cassandra_zookeeper_kafka_setup.zip (or latest service pack) downloaded to your home directory from the download/license instructions sent out by our team.
Note: the .ZIP will pre-create a separate folder for its contents when extracted so there is no need to pre-create a separate folder for it.
2. Review Kafka's recommendations, ie: (Open|Oracle)JDK/JRE, memory, FS selection, params, etc. (see http://kafka.apache.org/documentation/#java till the Monitoring section for more details, however keep in mind most of it was written when deploying as a cluster).
3. If using a firewall, ensure the following port is accessible (consult your local network admin if required): TCP port 9092 (this is the port to listen to for client connections).

Download, Install, Configure & Run Apache Kafka
1. Download Kafka 2.13-3.2.1 from http://kafka.apache.org/downloads#3.2.1 (ie: wget https://archive.apache.org/dist/kafka/3.2.1/kafka_2.13-3.2.1.tgz)
2. Use tar to extract the .tar.gz file to /opt/ , ie: KAFKA_build_ver=2.13-3.2.1 ; sudo tar -xvzf kafka_${KAFKA_build_ver}.tgz -C /opt/ ; where KAFKA_build_ver = the version you downloaded, ex: 2.13-3.2.1
3. Create/update a symlink to the current version, ie: sudo ln -nfs /opt/kafka_${KAFKA_build_ver} /opt/kafka-current
...
8. Start the Kafka service, ie: /opt/kafka_${, you should get some console output with no errors. Hit CTRL-C to halt. KAFKA_build_ver}${KAFKA_build_ver}
Note, Apache Kafkfa doesn't include a native systemd .service file by default. While systemd will dynamically create one at runtime via its SysV compatibility module, you may wish to create one yourself to exercise better control over the various service parameters. For your convenience we have created a systemd kafka.service file (included in the syndeia-cloud-3.4_cassandra_zookeeper_kafka_setup.zip download). To use this, copy it to /etc/systemd/system, reload systemd units, enable kafka to start on boot and start the service, ie: sudo cp <service_file_download_dir>/kafka.service /etc/systemd/system/. && sudo systemctl daemon-reload && sudo systemctl enable kafka && sudo systemctl start kafka
...
Before making the image you may wish to first stop and optionally disable the service temporarily to prevent auto-start on boot, ie: sudo systemctl disable kafkfa.

Multi-Node (Cluster) Setup Instructions (Adding nodes to an existing single-node SC deployment)
11. Deploy another instance of your Kafka base image.
12. Make any appropriate changes for the MAC address (ex: in the VM settings and/or udev, if used).
13. Setup forward & reverse DNS records on your DNS server (consult your IT admin/sysadmin if required) and set the hostname and primary DNS suffix on the machine itself (sudo hostnamectl set-hostname <new_Kafka_node_FQDN> where FQDN = Fully Qualified Domain Name, ex: kafkfa2.mycompany.com )
14. SSH to the IP (or the FQDN of the new node if DNS has already propagated).
...
16. Repeat steps 11 ~ 15 for each additional cluster node.

Validating Kafka Operation (or Cluster Replication) for 1-node (or multiple nodes)
17. To validate Kafka operation, we create a sample test topic, start a producer, put some messages into the queue, start a consumer script, and validate we see them. To do this, perform the following steps:
