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

提供一个yml文件验证器：https://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
```
save 保存
