centos7下docker-compose安装kafka集群

 

0 安装docker（略）

1. 安装docker-compose

1、下载安装文件

curl -L https://github.com/docker/compose/releases/download/1.24.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

 

2、添加权限

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

 3、查看版本

docker-compose --version

 

2. 安装zookeeper及kafka镜像

1、查看镜像

docker search zookeeper
docker search kafka 

2、下载镜像

docker pull zookeeper
docker pull wurstmeister/kafka
docker pull hlebalbau/kafka-manager #管理工具

 

3. 创建必要文件及文件夹（docker-compose.yml同一目录下）

1、 首先创建根目录

    mkdir /mq        

2、kafka文件夹

   cd /mq
 mkdir kafka1
 mkdir kafka2
 mkdir kafka3

3、zookeeper文件夹

mkdir zookeeper1
mkdir zookeeper2
mkdir zookeeper3

zookeeper配置文件

mkdir zooConfig
cd zooConfig
mkdir zoo1
mkdir zoo2
mkdir zoo3

 4、在zoo1,zoo2,zoo3中分别创建myid文件，并写入分别写入id数字，如zoo1中的myid中写入1

 

5、创建zoo配置文件zoo.cfg

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=/data
dataLogDir=/datalog
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
autopurge.purgeInterval=1
server.1= zoo1:2888:3888
server.2= zoo2:2888:3888
server.3= zoo3:2888:3888

 

 

4. 创建网络

docker network create --driver bridge --subnet 172.23.0.0/25 --gateway 172.23.0.1  zookeeper_network 

4. 创建docker-compose.yml文件

version: '2'

6. 启停集群

1、启动集群

docker-compose -f docker-compose.yml up -d 

2、停止集群

docker-compose -f docker-compose.yml stop 

3、单个节点停止

docker rm -f zoo1 

7. 查看zookeeper集群是否正常

docker exec -it zoo1 bash
bin/zkServer.sh status # mode 为leader或follower正常 

8. 创建topic

1、验证，每个list理论上都可以看到新建的topic

docker exec -it kafka1 bash
kafka-topics.sh --create --zookeeper zoo1:2181 --replication-factor 1 --partitions 3 --topic test001
kafka-topics.sh --list --zookeeper zoo1:2181
kafka-topics.sh --list --zookeeper zoo2:2181
kafka-topics.sh --list --zookeeper zoo3:2181

 2、生产消息

kafka-console-producer.sh --broker-list kafka1:9092,kafka2:9093,kafka3:9094 --topic test001

 3、消费消息

kafka-console-consumer.sh --bootstrap-server kafka1:9092,kafka2:9093,kafka3:9094 --topic test001 --from-beginning

 

9. 防火墙开启相关端口

firewall-cmd --zone=public --add-port=9000/tcp --permanent
firewall-cmd --reload
