tar -xzf kafka_2.13-4.0.0.tgz

mv kafka_2.13-4.0.0 kafka

cd kafka

# 随便一台节点运行生成随机uuid，后面每台节点都要使用此uuid

bin/kafka-storage.sh random-uuid 生成的uuid（IyyjPwZcTa2LHKkV1rj5pg）

# 每个节点需要在config/server.properties中配置相关内容

node.id

controller.quorum.voters=1@192.168.10.10:9093,2@192.168.10.20:9093,3@192.168.10.30:9093

log.dirs=/opt/kafka/log/kraft-combined-logs

num.partitions=16

# 每台节点设置日志目录的格式，$KAFKA_CLUSTER_ID应为上面生成的值，每个节点都要用相同的uuid

bin/kafka-storage.sh format -t IyyjPwZcTa2LHKkV1rj5pg -c config/server.properties

# 启动 Kafka 服务，每台节点都执行

bin/kafka-server-start.sh -daemon /opt/kafka/config/server.properties

# 测试kafka集群

# 创建主题名为cluster-topic存储事件

bin/kafka-topics.sh --bootstrap-server 192.168.10.10:9092 --create --topic cluster-topic1 --partitions 3 --replication-factor 3

# 在其他节点(9092)查询该topic

bin/kafka-topics.sh --describe --topic cluster-topic1 --bootstrap-server 192.168.10.20:9092

# 将事件写入主题

bin/kafka-console-producer.sh --topic cluster-topic1 --bootstrap-server 192.168.10.10:9092

This is my first event

This is my second event

# 读取事件

bin/kafka-console-consumer.sh --topic cluster-topic --from-beginning --bootstrap-server 192.168.10.10:9092

# 删除主题

bin/kafka-topics.sh --bootstrap-server 192.168.10.10:9092 --delete --topic cluster-topic

# 配置systemd服务

# 先关闭kafka服务

/opt/kafka/bin/kafka-server-stop.sh config/server.properties

# 配置服务
