Kafka Cluster build Step 1.
Machine preparation In this article, we will prepare three machines to build Kafka cluster, IP address is 192.168.1.1,192.168.1.2,192.168.1.3, and three machines network interoperability. 2. Download and install kafka_2.10-0.8.2.1 download address: https://kafka.apache.org/downloads.html do

the Kafka cluster configuration typically has three methods , namely
(1) Single node–single broker cluster;
(2) Single node–multiple broker cluster;(3) Multiple node–multiple broker cluster.

Kafka Cluster management, state saving is realized through zookeeper, so we should build zookeeper cluster first
Zookeeper Cluster setup
First, the SOFTWARE environment:
The zookeeper cluster requires more than half of the node t
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

).Kafka is an explicit distributed system. It assumes that data producers, brokers, and consumers are scattered on multiple machines.In contrast, traditional message queues cannot be well supported (for example, ultra-long unprocessed data cannot be effectively persisted ). Kafka provides two guarantees for Data availability:(1 ).Messages sent by the producer to the partition of the Topic are sent in the o
To demonstrate the effect of the cluster, a virtual machine (window 7) is prepared, and a single IP multi-node zookeeper cluster is built in the virtual machine (the same is true for multiple IP nodes), and Kafka is installed in both native (Win 7) and virtual machines.Pre-preparation instructions:1.
