kafka_2.11-2.0.0_常用操作
参考博文：kafka 1.0 中文文档（九）：操作
参考博文：kafka集群管理工具kafka-manager部署安装
以下操作可以在mini01、mini02、mini03任意一台操作即可。
1. kafka通过网页管理
参考博文：kafka集群管理工具kafka-manager部署安装
2. 创建topic
# 参数说明 --replication-factor 表示有2个副本
# --partitions 表示有4个分区
[yun@mini01 ~]$ kafka-topics.sh --create --zookeeper mini01: --replication-factor --partitions --topic test
Created topic "test".
[yun@mini01 ~]$ kafka-topics.sh --create --zookeeper mini01: --replication-factor --partitions --topic zhang
Created topic "zhang".
[yun@mini01 ~]$ kafka-topics.sh --list --zookeeper mini01: # 再次查看
zhang
test
2.1. 各主机信息查看
mini01
[yun@mini01 logs]$ pwd
/app/kafka/logs
[yun@mini01 logs]$ ll
total
………………
drwxrwxr-x yun yun Sep : test-
drwxrwxr-x yun yun Sep : test-

drwxrwxr-x yun yun Sep : test-
drwxrwxr-x yun yun Sep : test-
3. 修改topic
3.1. 增加分区数
注意：分区数不能减少
Kafka目前不支持减少主题的分区数量。
[yun@mini01 ~]$ kafka-topics.sh --list --zookeeper mini01:
__consumer_offsets
test
test01
test02
test03
test04
zhang
[yun@mini01 ~]$ kafka-topics.sh --describe --zookeeper mini01: --topic test01
Topic:test01 PartitionCount: ReplicationFactor: Configs:
Topic: test01 Partition: Leader: Replicas: Isr:
Topic: test01 Partition: Leader: Replicas: Isr:
Topic: test01 Partition: Leader: Replicas: Isr:
Topic: test01 Partition: Leader: Replicas: Isr:
Topic: test01 Partition: Leader: Replicas: Isr:
[yun@mini01 ~]$ kafka-topics.sh --alter --zookeeper mini01: --partitions --topic test01 # 失败，分区数不能减少
WARNING: If partitions are increased for a topic that has a key, the partition logic or ordering of the messages will be affected
Error while executing topic command : The number of partitions for a topic can only be increased. Topic test01 currently has partitions, would not be an increase.
[-- ::,] ERROR org.apache.kafka.common.errors.InvalidPartitionsException: The number of partitions for a topic can only be increased. Topic test01 currently has partitions, would not be an increase.
(kafka.admin.TopicCommand$)
[yun@mini01 ~]$ kafka-topics.sh --alter --zookeeper mini01: --partitions --topic test01 # 增加分区数
WARNING: If partitions are increased for a topic that has a key, the partition logic or ordering of the messages will be affected
Adding partitions succeeded!
[yun@mini01 ~]$ kafka-topics.sh --describe --zookeeper mini01: --topic test01
Topic:test01 PartitionCount: ReplicationFactor: Configs:
Topic: test01 Partition: Leader: Replicas: Isr:
Topic: test01 Partition: Leader: Replicas: Isr:
Topic: test01 Partition: Leader: Replicas: Isr:
Topic: test01 Partition: Leader: Replicas: Isr:
Topic: test01 Partition: Leader: Replicas: Isr:
Topic: test01 Partition: Leader: Replicas: Isr:
Topic: test01 Partition: Leader: Replicas: Isr:
4. 删除topic
# server.properties中设置delete.topic.enable=true 【当前版本默认就是true】否则只是标记删除或者直接重启
[yun@mini01 ~]$ kafka-topics.sh --delete --zookeeper mini01: --topic test
Topic test is marked for deletion.
Note: This will have no impact if delete.topic.enable is not set to true.
[yun@mini01 ~]$ kafka-topics.sh --list --zookeeper mini01: # 再次查看 只有 zhang，则表示真的删除了
zhang
5. 查看所有topic
[yun@mini01 ~]$ kafka-topics.sh --list --zookeeper mini01:
__consumer_offsets
test
zhang
6. 查看某个Topic的详情
[yun@mini01 ~]$ kafka-topics.sh --describe --zookeeper mini01: --topic zhang
Topic:zhang PartitionCount: ReplicationFactor: Configs:
Topic: zhang Partition: Leader: Replicas: ,, Isr: ,,
Topic: zhang Partition: Leader: Replicas: ,, Isr: ,,
Topic: zhang Partition: Leader: Replicas: ,, Isr: ,,
Topic: zhang Partition: Leader: Replicas: ,, Isr: ,,
7. 通过shell命令生产消息
7.1. 输入单条数据
[yun@mini01 ~]$ kafka-console-producer.sh --broker-list mini01: --topic zhang
>
>
>
>
>
>
>
>
>
7.2. 批量导入数据
[yun@mini01 zhangliang]$ kafka-console-producer.sh --broker-list mini01: --topic liang < .info
8. 通过shell命令消费消息
# --from-beginning 从最开始读取
# kafka-console-consumer.sh --zookeeper mini01: --from-beginning --topic zhang # 老版本
[yun@mini01 ~]$ kafka-console-consumer.sh --bootstrap-server mini01: --from-beginning --topic zhang
9. 消费组消费
9.1. 创建topic
[yun@mini01 ~]$ kafka-topics.sh --create --zookeeper mini01: --replication-factor --partitions --topic order
Created topic "order".
[yun@mini01 ~]$ kafka-topics.sh --list --zookeeper mini01: # 查看所有topic列表
__consumer_offsets
order
test
zhang
[yun@mini01 ~]$ kafka-topics.sh --describe --zookeeper mini01: --topic order # 查看topic详情
Topic:order PartitionCount: ReplicationFactor: Configs:
Topic: order Partition: Leader: Replicas: Isr:
Topic: order Partition: Leader: Replicas: Isr:

9.3. 消费组消费消息
mini02机器上运行
# --group 指定组
[yun@mini02 ~]$ kafka-console-consumer.sh --bootstrap-server mini01: --topic order --group order-group
mini03机器上运行
# --group 指定组
[yun@mini03 ~]$ kafka-console-consumer.sh --bootstrap-server mini01: --topic order --group order-group # 新开一个窗口执行
[yun@mini03 ~]$ kafka-console-consumer.sh --bootstrap-server mini01: --topic order --group order-group
表示order-group消费组有3个消费者，消费topic order的信息。
9.4. 消费组消费位置信息查看
[yun@mini01 ~]$ kafka-consumer-groups.sh --bootstrap-server mini01: --describe --group order-group # 查看消费情况 TOPIC PARTITION CURRENT-OFFSET LOG-END-OFFSET LAG CONSUMER-ID HOST CLIENT-ID

console-consumer-
console-consumer-
console-consumer-
console-consumer-
console-consumer-
console-consumer-
console-consumer-
# 删除一个或多个组
[yun@mini01 ~]$ kafka-consumer-groups.sh --bootstrap-server mini01: --delete --group console-consumer- --group console-consumer-
Deletion of requested consumer groups ('console-consumer-31713', 'console-consumer-11661') was successful.
[yun@mini01 ~]$ kafka-consumer-groups.sh --bootstrap-server mini01: --list

11. 增加副本因子
[yun@mini01 kafka_20180916]$ kafka-topics.sh --create --zookeeper mini01: --replication-factor --partitions --topic order
Created topic "order".
[yun@mini01 kafka_20180916]$ kafka-topics.sh --describe --zookeeper mini01: --topic order
Topic:order PartitionCount: ReplicationFactor: Configs:
Topic: order Partition: Leader: Replicas: Isr:
Topic: order Partition: Leader: Replicas: Isr:
Topic: order Partition: Leader: Replicas: Isr:
Topic: order Partition: Leader: Replicas: Isr:
要求：topic order 的副本数由1变为2， 之前每个分区在哪台机器上在上面已给出。
说明：part 0分布在群集0,1； part 1分布在集群1,2；part 2 分布在集群2,0；part 3分布在集群0,1。
11.1. 创建一个重新调整计划文件
[yun@mini01 kafka_20180916]$ cat increase-replication-factor.json
{
"version":,
"partitions":[
{"topic": "order","partition": ,"replicas": [,]},
{"topic": "order","partition": ,"replicas": [,]},
{"topic": "order","partition": ,"replicas": [,]},
{"topic": "order","partition": ,"replicas": [,]}
]
}
11.2. 语句执行
[yun@mini01 kafka_20180916]$ kafka-reassign-partitions.sh --zookeeper mini01: --reassignment-json-file increase-replication-factor.json --execute
Current partition replica assignment {"version":,"partitions":[{"topic":"order","partition":,"replicas":[],"log_dirs":["any"]},{"topic":"order","partition":,"replicas":[],"log_dirs":["any"]},{"topic":"order","partition":,"replicas":[],"log_dirs":["any"]},{"topic":"order","partition":,"replicas":[],"log_dirs":["any"]}]} Save this to use as the --reassignment-json-file option during rollback
Successfully started reassignment of partitions.
11.3. 查看是否执行成功
[yun@mini01 kafka_20180916]$ kafka-reassign-partitions.sh --zookeeper mini01: --reassignment-json-file increase-replication-factor.json --verify
Status of partition reassignment:
Reassignment of partition order- completed successfully
Reassignment of partition order- completed successfully
Reassignment of partition order- completed successfully
Reassignment of partition order- completed successfully
11.4. 再次查看该topic详情
[yun@mini01 kafka_20180916]$ kafka-topics.sh --describe --zookeeper mini01: --topic order # 由下可见分配成功
Topic:order PartitionCount: ReplicationFactor: Configs:
Topic: order Partition: Leader: Replicas: , Isr: ,
Topic: order Partition: Leader: Replicas: , Isr: ,
Topic: order Partition: Leader: Replicas: , Isr: ,
Topic: order Partition: Leader: Replicas: , Isr: ,
12. 创建partitions时在broker的分配机制
kafka-topics.sh --create --zookeeper mini01: --replication-factor --partitions --topic test01
kafka-topics.sh --create --zookeeper mini01: --replication-factor --partitions --topic test02
注意在各机器上partitions的分布
