基于docker-compose构建kafka，修改默认分区

同样基于docker-compose安装，Docker快速部署nginx中有讲到，不在重述

1. 编写docker-compose.yml

个人习惯放在/opt/下，如/opt/kafka, /opt/nginx, docker-compose.yml如下

version: '3'
services:
  zookeeper:
    image: 大专栏  Docker快速安装kafkalass="string">wurstmeister/zookeeper
    ports:
      - "2181:2181" 
  kafka:
    image: wurstmeister/kafka
    ports:
      - "9092:9092"
    environment:
      KAFKA_ADVERTISED_HOST_NAME: 192.168.153.152 # 宿主IP地址，此为我虚拟机地址
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

2. 启动kafka

docker-compose up -d

Creating kafka_kafka_1 … done
Creating kafka_zookeeper_1 … done

3. 消息生产消费验证

docker exec -it kafka_kafka_1 /bin/bash # 进入kafka终端

# 创建test主题，副本1，分区1
kafka-topics.sh --create --topic test --zookeeper kafka_zookeeper_1:2181 --replication-factor 1 --partitions 1

kafka-topics.sh --list --zookeeper kafka_zookeeper_1:2181 # 查看刚才创建的test分区

# 发布消息，输入几条消息后，按^C退出发布
kafka-console-producer.sh --topic=test --broker-list kafka_kafka_1:9092

# 接收消息
kafka-console-consumer.sh --bootstrap-server kafka_kafka_1:9092 --from-beginning --topic test

如果正常的话，发布的消息能够接收到，开始愉悦的kafka之旅吧~~~
