Recently want to test the performance of Kafka, toss a lot of genius to Kafka installed to the window. The entire process of installation is provided below, which is absolutely usable and complete, while providing complete Kafka Java client code to communicate with Kafka.

Kafka cluster configuration is relatively simple. For better understanding, the following three configurations are introduced here. Single Node: A broker Cluster Single Node: cluster of multiple Brokers Multi-node: Multi-broker Cluster 1. Single-node single-broker instance Configuration 1. first, start the zookeeper service Kafka. It provides the script for starting zookeeper (in the

Start the Zookeeper service Since zookeeper is already available in the Kafka package, the script that launches the Kafka (in the Kafka_2.10-0.8.2.2/bin directory) and the Zookeeper configuration file (in KAFKA_2.10-0.8.2.2/ Config directory): [Root@master kafka_2.10-0.8.2.2]# bin/zookeeper-server-start.sh Config/zookeeper.properties Zookeeper configuration file zookeeper.properties The key attributes in
