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 to survive to be externally serviced, so the number of servers should be 2*n+1, where 3 node is used to build the zookeeper cluster.
1.3 Linux servers are created using the Docker container, and the IP address isnodea:172.17.0

Kafka, originally developed by LinkedIn, is a distributed, partitioned, multi-replica, multi-subscriber, zookeeper-coordinated distributed log system (also known as an MQ system) that can be used for Web/nginx logs, access logs, messaging services, etc. LinkedIn contributed to the Apache Foundation and became the top open source project in 2010.

Zookeeper uses zookeeper-3.4.7.tar.gz and kafka_2.10-0.9.0.0.tgz. First, install JDK (jdk-7u9-linux-i586.tar.gz) and SSH. The IP addresses are allocated to kafka1 (192.168.56.136), kafka2 (192.168.56.137), and kafka3 (192.168.56.138 ). The following describes how to install SSH and how to build and use zookeeper and Kafka clusters.
