Kafka Installation

Installation procedures for Apache Kafka across different deployment scenarios.

---

Installation Methods

Method	Use Case	Prerequisites
Binary Installation	Development, production	Java 11+
Docker	Development, testing	Docker
Kubernetes	Cloud-native production	Kubernetes cluster
Package Manager	Linux servers	apt/yum

---

Binary Installation

Download

# Kafka 4.3.x (current stable)
curl -O https://downloads.apache.org/kafka/4.3.0/kafka_2.13-4.3.0.tgz
tar -xzf kafka_2.13-4.3.0.tgz
cd kafka_2.13-4.3.0

KRaft Mode (Recommended)

KRaft mode eliminates the ZooKeeper dependency. This is the recommended deployment mode for Kafka 3.3+.

# Generate cluster ID
KAFKA_CLUSTER_ID="$(bin/kafka-storage.sh random-uuid)"

# Format storage directories
bin/kafka-storage.sh format \
  -t $KAFKA_CLUSTER_ID \
  -c config/kraft/server.properties

# Start broker
bin/kafka-server-start.sh config/kraft/server.properties

KRaft Configuration

Kubernetes

While the Docker container above can be deployed in Kubernetes, we recommend using Strimzi for production-grade Kafka deployments on Kubernetes. Strimzi provides a complete operator-based solution with native Kubernetes integration, automated management, and enhanced operational capabilities.

For detailed instructions on deploying Kafka with Strimzi and AxonOps monitoring integration, see the Kubernetes Strimzi Installation Guide.

System Configuration

Linux Kernel Tuning

File Descriptor Limits

/etc/security/limits.conf

kafka soft nofile 100000
kafka hard nofile 100000
kafka soft nproc 32768
kafka hard nproc 32768

Disk Configuration

Recommendation	Rationale
Use XFS or ext4	Reliable filesystems for append-heavy workloads
Disable atime	Reduces unnecessary disk writes
Use separate disks for logs	Isolates I/O for different log directories
RAID 10 or JBOD	Balance between performance and redundancy

# Mount options for Kafka data directory
/dev/sdb1 /var/kafka-logs xfs defaults,noatime 0 2

Verification

# Check broker is running
bin/kafka-broker-api-versions.sh --bootstrap-server localhost:9092

# Create test topic
bin/kafka-topics.sh --create \
  --topic test \
  --bootstrap-server localhost:9092 \
  --partitions 3 \
  --replication-factor 1

# List topics
bin/kafka-topics.sh --list --bootstrap-server localhost:9092

# Produce test message
echo "test message" | bin/kafka-console-producer.sh \
  --topic test \
  --bootstrap-server localhost:9092

# Consume test message
bin/kafka-console-consumer.sh \
  --topic test \
  --from-beginning \
  --bootstrap-server localhost:9092 \
  --max-messages 1
