一.首先安装docker，在Linux系统依次输入以下命令。
1.sudo yum install -y yum-utils device-mapper-persistent-data lvm2
2.sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
3.sudo yum makecache fast
4.sudo yum -y install docker-ce
5.sudo service docker start

然后配置docker镜像加速，依次输入以下命令（可不配）
1.sudo mkdir -p /etc/docker
2.sudo tee /etc/docker/daemon.conf <<-'EOF'
{
"registry-mirrors": ["https://ung2thfc.mirror.aliyuncs.com"]
}
EOF
3.sudo systemctl daemon-reload
4.sudo systemctl restart docker

二.安装docker-compose

1.下载docker-compose二进制文件安装

sudo curl -L https://get.daocloud.io/docker/compose/releases/download/1.25.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

2.添加可执行权限

sudo chmod +x /usr/local/bin/docker-compose

测试安装结果

docker-compose --version

三.安装kafka

创建docker-compose-test.yml文件

vim docker-compose-test.yml

version: "3.3"
services:
    zookeeper:
        image: zookeeper:3.5.5
        restart: always
        container_name: zookeeper
        ports:
            - "2181:2181"
        expose:
            - "2181"
        environment:
            - ZOO_MY_ID=1
    kafka:
        image: wurstmeister/kafka:2.12-2.2.1
        restart: always
        container_name: kafka
        environment:
            - KAFKA_BROKER_ID=1
            - KAFKA_LISTENERS=PLAINTEXT://kafka:9090
            - KAFKA_ZOOKEEPER_CONNECT=zookeeper:2181
            - KAFKA_MESSAGE_MAX_BYTES=2000000
        ports:
            - "9090:9090"
        depends_on:
            - zookeeper

将 docker-compose-test.yml 放入你的目录，运行部署脚本

docker-compose -f docker-compose-test.yml up -d

查看两者的日志，检查是否正常启动

docker logs -f zookeeper 

docker logs -f kafka 

 查看一下，Zookeeper 中注册的 Broker 信息

docker exec -it zookeeper bash bin/zkCli.sh

ls /brokers/ids

get /brokers/ids/1

输入 quit 退出

配置宿主机对 kafka 映射

编辑/etc/hosts，添加宿主机ip kafka

vim /etc/hosts

创建Topic ,没有输出，说明创建 Topic 成功！

docker run -it --rm --network host wurstmeister/kafka:2.12-2.2.1 bash /opt/kafka/bin/kafka-topics.sh --bootstrap-server kafka:9090  --create --topic logsTopic --partitions 1 --replication-factor 1

生产一条测试消息

docker run -it --rm --network host wurstmeister/kafka:2.12-2.2.1 bash /opt/kafka/bin/kafka-console-producer.sh --broker-list kafka:9090 --topic logsTopic

输入回车，发送消息； ctrl + c 断开连接

创建消费者，消费消息测试

docker run -it --rm --network host wurstmeister/kafka:2.12-2.2.1 bash /opt/kafka/bin/kafka-console-consumer.sh --bootstrap-server kafka:9090  --topic logsTopic  --from-beginning

消费成功!
