Frequently asked questions
What port does Apache Kafka use?
Apache Kafka commonly uses these ports: 9092, 2181. The default port is 9092. These are community database references — actual configuration may differ.
How do I check if Apache Kafka is running?
Run sudo ss -tlpn 'sport = :9092 or sport = :2181' on the server to check for listening processes on these ports. Also use systemctl status <service> to check the service state. Without root you may not see other users' processes. A listening port alone does not prove the software identity — verify with the config file and process name.
