集群规划

我们准备部署6个容器，分别安装3个zookeeper和3个Kafka，总共6个服务下表为各个服务的IP和端口映射

安装Docker的服务编排工具

1.运行以下命令以下载Docker Compose的当前稳定版本：

sudo curl -L "https://github.com/docker/compose/releases/download/1.25.5/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

2.将可执行权限应用于二进制文件：

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

3.测试安装

docker-compose --version

官网安装地址：docs.docker.com/compose/ins…

创建网络

docker network create --subnet=172.20.0.0/24 br17219

拉取镜像(建议网络不好的同学先拉起镜像)

docker pull wurstmeister/zookeeper
dcoker pull wurstmeister/kafka
docker pull sheepkiller/kafka-manager:latest

通过 docker ps 查看已经拉起的镜像

编写docker-compose

1.新建一个 docker-compose.yml

vim docker-compose.yml

编写服务编排脚本

    image: wurstmeister/zookeeper

提供一个yml文件验证器：yamlvalidator.com/ 3.：wq 保存并退出

以下命令在docker-compose.yml 文件目录执行

4.验证（docker-compose.yml）文件配置，当配置正确时，不输出任何内容，当文件配置错误，输出错误信息

docker-compose config  -q  

5.构建docker-compose

docker-compose build 

6.启动docker-compose

docker-compose up -d

7.查看状态

docker-compose ps

登录kafka-manager管理Kafka

http//:ip:9010

Cluster Name 随便起

Cluster Zookeeper Hosts

 zoo1:2181,zoo2:2181,zoo3:2181
