https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html#license-lightbox
tar -zxvf jdk-8u281-linux-x64.tar.gz

2. 解压
tar -zxvf kafka_2.12-2.7.0.tgz
3. 启动
# 需先启动zookeeper
# -daemon 可启动后台守护模式
# 如果你已经启动了zookeeper 就不用启动下面这 (kafka默认提供有zookeeper)
bin/zookeeper-server-start.sh config/zookeeper.properties
# 启动Kafka服务端
bin/kafka-server-start.sh config/server.properties
4. 启动kafka客户端测试
# 创建一个话题,test话题2个分区
bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 2 --topic test
Created topic "test".
# 显示所有话题
bin/kafka-topics.sh --list --zookeeper localhost:2181
test
# 显示话题信息
bin/kafka-topics.sh --describe --zookeeper localhost:2181 --topic test
Topic:test PartitionCount:2 ReplicationFactor:1 Configs:
Topic: test Partition: 0 Leader: 0 Replicas: 0 Isr: 0
Topic: test Partition: 1 Leader: 0 Replicas: 0 Isr: 0
# 启动一个生产者(输入消息)
bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test
[等待输入自己的内容 出现>输入即可]
