1. 配置zookeeper
https://www.cnblogs.com/convict/p/16438634.html
2. 下载kafka
http://archive.apache.org/dist/kafka/2.8.0/kafka_2.12-2.8.0.tgz
3. 解压
tar -zxvf apache-zookeeper-3.6.3-bin.tar.gz
放到opt目录下
mv zookeeper-3.6.3/ /opt
4. 配置kafka数据目录
mkdir -p /data/kafka/k1/log
mkdir -p /data/kafka/k2/log
mkdir -p /data/kafka/k3/log
5. 配置文件
cd /opt/kafka_2.12-2.8.0/config
config目录下有个server.properties，这个是模板配置文件，以此为模板复制一个server1.properties
cp server.properties server1.properties
修改server1.properties内容
broker.id=1
listeners=PLAINTEXT://:9092
advertised.listeners=PLAINTEXT://192.168.123.201:9092 # 暴露给外部的地址
log.dirs=/data/kafka/k1/log
zookeeper.connect=127.0.0.1:2181,127.0.0.1:2182,127.0.0.1:2183
以server1.properties，复制server2.properties
cp server.properties server2.properties
修改server2.properties
broker.id=2
listeners=PLAINTEXT://:9093
advertised.listeners=PLAINTEXT://192.168.123.201:9093
log.dirs=/data/kafka/k2/log
zookeeper.connect=127.0.0.1:2181,127.0.0.1:2182,127.0.0.1:2183
以server1.properties，复制server3.properties
cp server.properties server3.properties
修改server3.properties
broker.id=3
listeners=PLAINTEXT://:9094
advertised.listeners=PLAINTEXT://192.168.123.201:9094
log.dirs=/data/kafka/k3/log
zookeeper.connect=127.0.0.1:2181,127.0.0.1:2182,127.0.0.1:2183
6. 启动kafka集群
分开多个shell启动
/opt/kafka_2.12-2.8.0/bin/kafka-server-start.sh /opt/kafka_2.12-2.8.0/config/server1.properties
/opt/kafka_2.12-2.8.0/bin/kafka-server-start.sh /opt/kafka_2.12-2.8.0/config/server2.properties
/opt/kafka_2.12-2.8.0/bin/kafka-server-start.sh /opt/kafka_2.12-2.8.0/config/server3.properties
7. 查看zookeeper上的brokers
/opt/zookeeper-3.6.3/bin/zkCli.sh
ls /
ls /brokers/ids
确认kafka注册到zookeeper上了
8. 测试
cd /opt/kafka_2.12-2.8.0/bin
8.1 测试创建topic
./kafka-topics.sh --bootstrap-server 127.0.0.1:9092,127.0.0.1:9093,127.0.0.1:9094 --replication-factor 1 --partitions 1 --create --topic MY_TEST_TOPIC
8.2 查看创建的topic
./kafka-topics.sh --bootstrap-server 127.0.0.1:9092,127.0.0.1:9093,127.0.0.1:9094 --list
8.3 测试生产者
./kafka-console-producer.sh --bootstrap-server 127.0.0.1:9092,127.0.0.1:9093,127.0.0.1:9094 --topic MY_TEST_TOPIC
8.4 测试消费者
./kafka-console-consumer.sh --bootstrap-server 127.0.0.1:9092,127.0.0.1:9093,127.0.0.1:9094 --topic MY_TEST_TOPIC --from-beginning
