Docker安装常用软件-Kafka集群

news2024/9/21 19:06:44

零、为了方便开发调试，使用kafka部署一套kafka环境，进行功能调试，方便快捷

一、部署zookeeper

1、下载镜像

docker pull wurstmeister/zookeeper

2、运行zookeeper镜像

docker run -d --restart=always --log-driver json-file --log-opt max-size=100m --log-opt max-file=2  --name zookeeper -p 2181:2181 -v /etc/localtime:/etc/localtime wurstmeister/zookeeper

备注：/etc/localtime:/etc/localtime 容器时间同步虚拟机的时间

启动后可以通过docker -ps 查看容器状态

二、搭建kafka

1、拉取镜像

docker pull wurstmeister/kafka

2、部署三个broker

2.1命名为：kafka0 端口：9092 brokerId: 0

docker run -d --name kafka0 -p 9092:9092 -e KAFKA_BROKER_ID=0 -e KAFKA_ZOOKEEPER_CONNECT=192.168.131.121:2181 -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.131.121:9092 -e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092 -v /etc/localtime:/etc/localtime -t wurstmeister/kafka

2.2命名为：kafka1 端口：9093 brokerId: 1

docker run -d --name kafka1 -p 9093:9093 -e KAFKA_BROKER_ID=1 -e KAFKA_ZOOKEEPER_CONNECT=192.168.131.121:2181 -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.131.121:9093 -e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9093 -v /etc/localtime:/etc/localtime -t wurstmeister/kafka

2.3命名为：kafka2 端口：9094 brokerId: 2

docker run -d --name kafka2 -p 9094:9094 -e KAFKA_BROKER_ID=2 -e KAFKA_ZOOKEEPER_CONNECT=192.168.131.121:2181 -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.131.121:9094 -e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9094 -v /etc/localtime:/etc/localtime -t wurstmeister/kafka

参数说明:

-e KAFKA_BROKER_ID=0 在kafka集群中，每个kafka都有一个BROKER_ID来区分自己
-e KAFKA_ZOOKEEPER_CONNECT=192.168.131.121:2181/kafka 配置zookeeper管理kafka的路径192.168.131.121:2181/kafka
-e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.131.121:9092 把kafka的地址端口注册给zookeeper，如果是远程访问要改成外网IP,类如Java程序访问出现无法连接。
-e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9092 配置kafka的监听端口
-v /etc/localtime:/etc/localtime 容器时间同步虚拟机的时间

三、验证kafka可用

1、进入容器

docker exec -it kafka0 bash  和 docker exec -it kafka1 bash

2、进入 /opt/kafka_2.13-2.8.1/bin/ 目录下

cd /opt/kafka_2.13-2.8.1/bin/

3、运行kafka生产者发送消息

 ./kafka-console-producer.sh --broker-list 192.168.131.121:9092,192.168.131.121:9093,192.168.131.121:9094 --topic sun

发送消息
> {"datas":[{"channel":"","metric":"temperature","producer":"ijinus","sn":"IJA0101-00002245","time":"1543207156000","value":"80"}],"ver":"1.0"}
>111
>222

4、运行kafka消费者接收消息

 ./kafka-console-consumer.sh --bootstrap-server 192.168.131.121:9092,192.168.131.121:9093,192.168.131.121:9094 --topic sun --from-beginning

{"datas":[{"channel":"","metric":"temperature","producer":"ijinus","sn":"IJA0101-00002245","time":"1543207156000","value":"80"}],"ver":"1.0"}
111
222

四、docker部署kafka管理平台

1、下载镜像

docker pull hlebalbau/kafka-manager

2、创建文件夹 \kafka\kafka-manager\docker-compose.yml

version: '2'
services:
  kafka-manager:
    image: sheepkiller/kafka-manager            
    environment:
      ZK_HOSTS:  192.168.131.121:2181
      APPLICATION_SECRET: "letmein"
    ports:
      - "39000:9000"
    expose:
      - "9000"

3、启动docker命令
