在一台服务器里面通过docker-compose部署zookeeper,kafka集群-CFANZ编程社区

在同一台服务器里面部署zk,kafka集群

1、首先在服务器安装docker和docker-compose环境（这里不多说）

2、拉取zookeeper和kafka镜像到服务器上

可以通过以下命令来查找相关的镜像

docker search   镜像名称
docker  search  zookeeper
docker search  kafka

3、通过命令docker pull 镜像名称：版本号拉取镜像

4、创建集群虚拟网络

docker network create --driver bridge --subnet 172.23.0.0/16 --gateway 172.23.0.1 zoo_kafka

如果报错：（开启防火墙）

5、分别创建目录/zookeeper, /kafka，并在相应的目录里面新建docker-compose.yml文件

6、部署zookeeper

docker-compose.yml内容如下:

version: '2'
services:
 zoo1:
  image: zookeeper:3.4 # 镜像名称
  restart: always # 当发生错误时自动重启
  hostname: zoo1
  container_name: zoo1
  privileged: true
  ports: # 端口
   - 2181:2181
  volumes: # 挂载数据卷
   - ./zoo1/data:/data
   - ./zoo1/datalog:/datalog 
  environment:
   TZ: Asia/Shanghai
   ZOO_MY_ID: 1 # 节点ID
   ZOO_PORT: 2181 # zookeeper端口号
   ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888 # zookeeper节点列表
  networks:
   default:
    ipv4_address: 172.23.0.11

 zoo2:
  image: zookeeper:3.4
  restart: always
  hostname: zoo2
  container_name: zoo2
  privileged: true
  ports:
   - 2182:2181
  volumes:
   - ./zoo2/data:/data
   - ./zoo2/datalog:/datalog
  environment:
   TZ: Asia/Shanghai
   ZOO_MY_ID: 2
   ZOO_PORT: 2181
   ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888
  networks:
   default:
    ipv4_address: 172.23.0.12

 zoo3:
  image: zookeeper:3.4
  restart: always
  hostname: zoo3
  container_name: zoo3
  privileged: true
  ports:
   - 2183:2181
  volumes:
   - ./zoo3/data:/data
   - ./zoo3/datalog:/datalog
  environment:
   TZ: Asia/Shanghai
   ZOO_MY_ID: 3
   ZOO_PORT: 2181
   ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888
  networks:
   default:
    ipv4_address: 172.23.0.13

networks:
 default:
  external:
   name: zoo_kafka

在/zookeeper路径下执行：

docker-compose up -d

7、部署kafka

docker-compose.yml内容如下:

version: '2'
services:
 broker1:
  image: wurstmeister/kafka
  restart: always
  hostname: broker1
  container_name: broker1
  privileged: true

8、测试是否搭建成功

进入kafka容器

docker exec -it broker1 /bin/bash

bash-5.1# kafka-topics.sh --create --zookeeper 172.23.0.11:2181 --replication-factor 1 --partitions 1 --topic test
Created topic test.
