## 2.4 Configurations

This topic describes about the various configurations for the kafka and integration services.

Setup Kafka

- Download Kafka from https://www.apache.org/dyn/closer.cgi?path=kafka/3.8.0/kafka_2.13-3.8.0.tgz.
- Install Zookeeper first and then Kafka.
- zookeeper-3.8.0/apache-zookeeper-3.8.0-bin.tar.gz. As zookeeper is embedded in Kafka.
- Follow the steps mentioned here - https://kafka.apache.org/quickstart.

Check if kafka is running

`Run cmd $ netstat –tlnp | grep :9092`

(9092 is default port of kafka)

Possible issue while starting kafka

- Kafka is not starting may be because zookeeper is not yet started run cmd

  `$ netstat –tlnp | grep :2181`
  (2181 is default port of zookeeper)
  If any service is not running on this port means zookeeper is down

- Check if any permission issue is there for kafka log folder.
- Create console producer and consumer for troubleshooting.
