1、拉取zookeeper镜像
kafka需要zookeeper管理，所以需要先安装zookeeper。 docker pull zookeeper:3.6 2、启动zookeeper容器docker run -d --name zookeeper -p 2181:2181 -v /etc/localtime:/etc/localtime zookeeper:3.6 3、拉取kafka镜像docker pull wurstmeister/kafka:2.12-2.5.0 [root@~]$docker pull wurstmeister/kafka:2.12-2.5.0 Trying to pull repository docker.io/wurstmeister/kafka ... 2.12-2.5.0: Pulling from docker.io/wurstmeister/kafka e7c96db7181b: Already exists f910a506b6cb: Pull complete b6abafe80f63: Pull complete 9daa71a3a025: Pull complete a4cad7b8f41a: Pull complete d77df92e7131: Pull complete Digest:

--name kafka -p 9002:9002 -e KAFKA_BROKER_ID=0 -e KAFKA_ZOOKEEPER_CONNECT=192.168.124.28:2181/kafka -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.124.28:9002 -e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9002 -v /etc/localtime:/etc/localtime wurstmeister/kafka:2.12-2.5.0 $ docker run -d --restart=always --log-driver json-file --log-opt max-size=100m --log-opt max-file=2 --name kafka -p 9002:9002 -e KAFKA_BROKER_ID=0 -e KAFKA_ZOOKEEPER_CONNECT=172.16.152.136:2181/kafka -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://172.16.152.136:9002 -e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9002 -v /etc/localtime:/etc/localtime wurstmeister/kafka:2.12-2.5.0 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=192.168.124.28:2181/kafka 配置zookeeper管理kafka的路径192.168.124.28:2181/kafka -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.124.28:9002 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://0.0.0.0:9002 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 复制代码 4.1 、可以设置的环境变量 [2021-04-19

KAFKA_ZOOKEEPER_CONNECT=192.168.124.28:2181/kafka -e KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://192.168.124.28:9002 -e KAFKA_LISTENERS=PLAINTEXT://0.0.0.0:9002 -v /etc/localtime:/etc/localtime

127.0.0.1:2181(CONNECTED) 7] ls / [zookeeper, kafka] [zk: 127.0.0.1:2181(CONNECTED) 8] ls /kafka [cluster, controller, controller_epoch, brokers, admin, isr_change_notification, consumers, config] [zk: 127.0.0.1:2181(CONNECTED) 9] 复制代码进入kafka容器查看 [root@blog]$docker exec -it d8e3973e228c /bin/sh / # ps -ef PID USER TIME COMMAND 1 root 0:08 /usr/lib/jvm/java-1.8-openjdk/jre/bin/java -Xmx1G -Xms1G
