kafka_shell操作

单机版

• 开启进程：

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

• 查看topic列表：

  ./bin/kafka-topics.sh --list --zookeeper localhost:2181

• 创建topic：

  ./bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic zhongqiu_test

• 查看topic描述：

  ./bin/kafka-topics.sh --describe --zookeeper localhost:2181 --topic zhongqiu_test

• producer发送信息：

  ./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic zhongqiu_test

• consumer接收信息：

  ./bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic zhongqiu_test --from-beginning

• 删除topic：

  ./bin/kafka-topics.sh --delete --zookeeper localhost:2181 --topic zhongqiu_test 

集群版

• 分别设置slave1、slave2两个节点的server.properties配置中的broker.id分别为1和2

• 创建topic：

  ./bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 3 --partitions 5 --topic zhongqiu_many_brokers
  ​

• 下面的命令会创建失败，原因是副本数大于实际broker个数

  ./bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 4 --partitions 5 --topic zhongqiu_many_brokers_4reps

• 查看topic描述：

  ./bin/kafka-topics.sh --describe --zookeeper localhost:2181 --topic zhongqiu_many_brokers
