Kafka命令行常用命令说明

基于0.8.0版本。

 

##查看topic分布情况kafka-list-topic.sh

bin/kafka-list-topic.sh --zookeeper 192.168.197.170:2181,192.168.197.171:2181 （列出所有topic的分区情况） bin/kafka-list-topic.sh --zookeeper 192.168.197.170:2181,192.168.197.171:2181 --topic test （查看test的分区情况） 其实kafka-list-topic.sh里面就一句  exec $(dirname $0)/kafka-run-class.sh kafka.admin.ListTopicCommand $@ 实际是通过 kafka-run-class.sh脚本执行的包kafka.admin下面的类

##创建TOPIC kafka-create-topic.sh

bin/kafka-create-topic.sh   --replica 2 --partition 8 --topic test  --zookeeper 192.168.197.170:2181,192.168.197.171:2181

创建名为test的topic， 8个分区分别存放数据，数据备份总共2份

bin/kafka-create-topic.sh   --replica 1 --partition 1 --topic test2  --zookeeper 192.168.197.170:2181,192.168.197.171:2181 结果 topic: test2 partition: 0 leader: 170 replicas: 170 isr: 170

##重新分配分区kafka-reassign-partitions.sh

这个命令可以分区指定到想要的--broker-list上 bin/kafka-reassign-partitions.sh --topics-to-move-json-file topics-to-move.json --broker-list "171" --zookeeper 192.168.197.170:2181,192.168.197.171:2181 --execute  cat topic-to-move.json {"topics":      [{"topic": "test2"}],      "version":1 }

##为Topic增加 partition数目kafka-add-partitions.sh

bin/kafka-add-partitions.sh --topic test --partition 2  --zookeeper  192.168.197.170:2181,192.168.197.171:2181 （为topic test增加2个分区）

##控制台接收消息

bin/kafka-console-consumer.sh --zookeeper  192.168.197.170:2181,192.168.197.171:2181  --from-beginning --topic test

##控制台发送消息

bin/kafka-console-producer.sh --broker-list  192.168.197.170:9092,192.168.197.171: 9092    --topic test 

##手动均衡topic, kafka-preferred-replica-election.sh

bin/kafka-preferred-replica-election.sh --zookeeper 192.168.197.170:2181,192.168.197.171:2181 --path-to-json-file preferred-click.json

cat preferred-click.json {  "partitions":   [     {"topic": "click", "partition": 0},     {"topic": "click", "partition": 1},     {"topic": "click", "partition": 2},     {"topic": "click", "partition": 3},     {"topic": "click", "partition": 4},     {"topic": "click", "partition": 5},     {"topic": "click", "partition": 6},     {"topic": "click", "partition": 7},

    {"topic": "play", "partition": 0},     {"topic": "play", "partition": 1},     {"topic": "play", "partition": 2},     {"topic": "play", "partition": 3},     {"topic": "play", "partition": 4},     {"topic": "play", "partition": 5},     {"topic": "play", "partition": 6},     {"topic": "play", "partition": 7}

  ] }

##删除topic,慎用，只会删除zookeeper中的元数据，消息文件须手动删除

bin/kafka-run-class.sh kafka.admin.DeleteTopicCommand --topic test666 --zookeeper 192.168.197.170:2181 ,192.168.197.171:2181
