预先准备：
上传软件至服务器192.168.105.125、192.168.105.129、192.168.130
kafka_2.12-2.2.0、zookeeper-3.4.8.tar.gz

一、zookeeper服务搭建

1. 下载

同时在125、129、130节点依次执行

mkdir /app
cd /app
wget https://archive.apache.org/dist/zookeeper/zookeeper-3.4.8/zookeeper-3.4.8.tar.gz

2. 解压

tar -zxvf zookeeper-3.4.8.tar.gz

3. 创建目录

cd /app/zookeeper-3.4.8
mkdir data logs

4. 调整配置

cp conf/zoo_sample.cfg conf/zoo.cfg
vim conf/zoo.cfg 

第一处：配置dataDir

dataDir=/app/zookeeper-3.4.8/data

第二处：新增配置

server.1=192.168.105.125:2288:3388
server.2=192.168.105.129:2288:3388
server.3=192.168.105.130:2288:3388

5. 配置myid

• 125节点

vim /app/zookeeper-3.4.8/data/myid

内容：1

• 129节点

vim /app/zookeeper-3.4.8/data/myid

内容：2

• 130节点

vim /app/zookeeper-3.4.8/data/myid

内容：3

6. 开放防火墙

125/129/130节点依次执行

firewall-cmd --zone=public --add-port=2181/tcp --permanent
firewall-cmd --zone=public --add-port=2288/tcp --permanent
firewall-cmd --zone=public --add-port=3388/tcp --permanent
firewall-cmd --reload
firewall-cmd --list-ports

7.启动验证zk

/app/zookeeper-3.4.8/bin/zkServer.sh start  /app/zookeeper-3.4.8/conf/zoo.cfg
/app/zookeeper-3.4.8/bin/zkServer.sh status  /app/zookeeper-3.4.8/conf/zoo.cfg

二、kafka集群搭建

同时在125、129、130节点依次执行

2.1. 下载软件

wget https://archive.apache.org/dist/kafka/2.2.0/kafka_2.12-2.2.0.tgz

2.2. 解压

tar -zxvf kafka_2.12-2.2.0.tgz

2.3. 配置

cd /app/kafka_2.12-2.2.0/config
cp server.properties server.properties.bak

• 125节点

###### 2.4. 防火墙
125/129/130节点依次执行

```bash
firewall-cmd --zone=public --add-port=9092/tcp --permanent
firewall-cmd --reload
firewall-cmd --list-ports

2.5. 启动kafka

启动kafka（第一次前台）

cd /app/kafka_2.12-2.2.0
./bin/kafka-server-start.sh config/server.properties 

启动kafka（前台）

cd /app/kafka_2.12-2.2.0
./bin/kafka-server-start.sh -daemon config/server.properties

129节点

130节点

三、测试验证

3.1. 创建一个主题

使用kafka，创建一个主题（topic）

bin/kafka-topics.sh --create --zookeeper 192.168.105.125:2181,192.168.105.129:2181,192.168.105.130:2181 --replication-factor 1 --partitions 1 --topic pis-business

3.2. 发送消息

bin/kafka-console-producer.sh --broker-list 192.168.105.125:9092 --topic pis-business

3.3. 消费消息

 bin/kafka-console-consumer.sh --bootstrap-server 192.168.105.125:9092  --from-beginning --topic pis-business
