2、部署kafka准备工作

3、编辑docker-compose.yml文件

# 配置zk集群

kafka配置解释：

    environment:### 通用配置# 允许使用kraft，即Kafka替代Zookeeper- KAFKA_ENABLE_KRAFT=yes# kafka角色，做broker，也要做controller- KAFKA_CFG_PROCESS_ROLES=broker,controller# 指定供外部使用的控制类请求信息- KAFKA_CFG_CONTROLLER_LISTENER_NAMES=CONTROLLER# 定义kafka服务端socket监听端口- KAFKA_CFG_LISTENERS=PLAINTEXT://:,CONTROLLER://:9093# 定义安全协议- KAFKA_CFG_LISTENER_SECURITY_PROTOCOL_MAP=CONTROLLER:PLAINTEXT,PLAINTEXT:PLAINTEXT# 使用Kafka时的集群id，集群内的Kafka都要用这个id做初始化，生成一个UUID即可- KAFKA_KRAFT_CLUSTER_ID=LelMdIFQkiUFvXCEcqRWA# 集群地址- KAFKA_CFG_CONTROLLER_QUORUM_VOTERS=@kafka11:9093,2@kafka22:9093,3@kafka33:9093# 允许使用PLAINTEXT监听器，默认false，不建议在生产环境使用- ALLOW_PLAINTEXT_LISTENER=yes# 设置broker最大内存，和初始内存- KAFKA_HEAP_OPTS=-XmxM -Xms256M # 不允许自动创建主题- KAFKA_CFG_AUTO_CREATE_TOPICS_ENABLE=false
​### broker配置# 定义外网访问地址（宿主机ip地址和端口）- KAFKA_CFG_ADVERTISED_LISTENERS=PLAINTEXT://.168.1.54:9292# broker.id，必须唯一- KAFKA_BROKER_ID=

4、启动服务

docker compose up -d

5、测试kafka

#进入机器kafka容器内部，创建并查看是否存在刚创建的topic，如果存在则说明Kafka集群搭建成功。
docker exec -it k1 bash
#创建topic
kafka-topics.sh --create --bootstrap-server 10.10.111.33:9092 --replication-factor 1 --partitions 3 --topic ODSDataSync
#查看topic
kafka-topics.sh --bootstrap-server 10.10.111.33:9092 --describe --topic ODSDataSync
docker exec -it k2 bash

注意：

ports 端口映射要与“environment”的端口保持一致

6、web监控管理

浏览器访问http://192.168.1.36:9000，输入用户名密码即可进入监控页面。

按照下图操作增加对kafka集群的监控
