Issue/Introduction

Kafka install issue for Topology installation
For the Topology installation,
We installed Kafka per the support pages as a cluster, and it installed on 1 host, but do not see kafka on the other 2 hosts of the cluster.

Is this normal behavior until the Topology module is installed via ansible?

Environment

DX NetOps 25.4.1

Resolution

 If you are installing the kafka separately, but for a clustered environment, the kafka install only installs on one node at a time.

Use the following process to install NetOps Kafka:

1. Verify the prerequisites.
2. Install NetOps Kafka using one of the following methods:
• Install from the command line. With this method, the NetOps Kafka installation prompts you to answer questions for the installation.
• Install in silent mode (silent installation). With this method, you install NetOps Kafka avoiding the prompts using the values that you define and provide in the answer.properties response file.
3. (If you plan to secure the connection) Configure SSL for NetOps Kafka Using the Self-Signed Certificates.
4. (If you are installing NetOps Kafka on a multi-node cluster) After you have installed NetOps Kafka on the primary node, repeat steps 1, 2, and (if you have configured SSL for the primary node) 3 for each node.

 

Look at step 4, after installing on one node, do the same on each additional node…
