docker-compose 搭建kafka集群

docker-compose搭建kafka集群

下载镜像

1.wurstmeister/zookeeper
2.wurstmeister/kafka
3.sheepkiller/kafka-manager

安装docker-compose(如果没有)

https://docs.docker.com/compose/install/

在每台机器创建文件夹(节点)

mkdir -p /database/kafka_log/zookeeper/zk1/conf
mkdir -p /database/kafka_log/zookeeper/zk1/data 
mkdir -p /database/kafka_log/zookeeper/zk1/log 
mkdir -p /database/kafka_log/zookeeper/zk2/conf 
mkdir -p /database/kafka_log/zookeeper/zk2/data 
mkdir -p /database/kafka_log/zookeeper/zk2/log 
mkdir -p /database/kafka_log/zookeeper/zk3/conf 
mkdir -p /database/kafka_log/zookeeper/zk3/data 
mkdir -p /database/kafka_log/zookeeper/zk3/log 
mkdir -p /database/kafka_log/kafka/kafka1/conf 
mkdir -p /database/kafka_log/kafka/kafka1/log 
mkdir -p /database/kafka_log/kafka/kafka2/conf 
mkdir -p /database/kafka_log/kafka/kafka2/log 
mkdir -p /database/kafka_log/kafka/kafka3/conf

创建docker网桥

1.docker network list 查看已生成的网桥
2.docker network inspect *****  (*****:网桥的名称)
3.docker  network  create  --driver  bridge  --subnet  172.16.0.0/25  --gateway  172.16.0.1  zookeeper_kafka 生成新的网桥(ip根据自己的docker网桥号的规律创建)
4.(可通信跳过)如果多机器网桥无法通信  ufw allow from 172.19.0.0/16  （172.19.0.0/16：容器的IP 和使用的端口） ufw 若果没有安装即可

注意

1. docker挂载的目录修改为自己机器创建的目录 
2. 查看镜像中zookeeper 的版本
3. 安装时docker指令 进行了rm 或者 down  删除容器 重新启动 要删除日志目录下的meta.properties文件
