docker 安装kafka

1.编写docker-compose.yml

version: '2'
services:
  zookeeper:
    image: wurstmeister/zookeeper
    ports:
      - "2181:2181"
  kafka:
    image: wurstmeister/kafka:2.11-0.11.0.3
    ports:
      - "9092:9092"
    environment:
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://:9092
      KAFKA_LISTENERS: PLAINTEXT://:9092
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /etc/localtime:/etc/localtime

2.启动server

在docker-compose.yml所在的文件夹下，执行命令docker-compose up -d，会先下载zookeeper和kafka的镜像，然后创建容器；

安装docker-compose

wget https://github.com/docker/compose/releases/download/1.14.0-rc2/docker-compose-Linux-x86_64

rename docker-compose-Linux-x86_64 docker-compose docker-compose-Linux-x86_64

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

再通过docker-compose version命令进行查看

3.开启端口

firewall-cmd --zone=public  --permanent --add-port=2181/tcp

firewall-cmd --zone=public  --permanent --add-port=9092/tcp

设置开启启动

docker update --restart=always kafka_zookeeper_1

docker update --restart=always kafka_kafka_1

3. 测试kafka

进入到kafka容器中 并创建topic 生产者，执行如下命令：

docker exec -it kafka_kafka_1 bash
cd /opt/kafka_2.11-0.11.0.3/bin/
./kafka-topics.sh --create --zookeeper zookeeper:2181 --replication-factor 1 --partitions 8 --topic test
./kafka-console-producer.sh --broker-list localhost:9092 --topic test

执行上述命令后，另起一个标签页，执行如下命令 创建kafka消费者消费消息：

docker exec -it kafka_kafka_1 bash
cd /opt/kafka_2.11-0.11.0.3/bin/
./kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning

执行完上述命令后，在生产者窗口中 输入任意内容回车，即可在消费者的窗口查看到消息
