因为上面的命令比较多，如果想要查看某个命令的具体参数，可以直接输入指定命令回车或者加上–help，如下

kafka-topics.sh命令帮助说明：kafka-topics.sh --help或者kafka-topics.sh

localhost:kafka_2.13-2.6.0 gaoxinfu$ pwd /Users/gaoxinfu/using/kafka_2.13-2.6.0 localhost:kafka_2.13-2.6.0 gaoxinfu$ bin/kafka-topics.sh --help This tool helps to create, delete, describe, or change a topic. Option Description ------ ----------- --alter Alter the number of partitions, replica assignment, and/or configuration for the topic. --at-min-isr-partitions if set when describing topics, only show partitions whose isr count is equal to the configured minimum. Not supported with the --zookeeper option. --bootstrap-server <String: server to REQUIRED: The Kafka server to connect connect to> to. In case of providing this, a direct Zookeeper connection won't be required. --command-config <String: command Property file containing configs to be config property file> passed to Admin Client. This is used only with --bootstrap-server option for describing and altering broker configs. --config <String: name=value> A topic configuration override for the topic being created or altered.The following is a list of valid configurations: cleanup.policy compression.type delete.retention.ms file.delete.delay.ms flush.messages flush.ms follower.replication.throttled. replicas index.interval.bytes leader.replication.throttled.replicas max.compaction.lag.ms max.message.bytes message.downconversion.enable message.format.version message.timestamp.difference.max.ms message.timestamp.type min.cleanable.dirty.ratio min.compaction.lag.ms min.insync.replicas preallocate retention.bytes retention.ms segment.bytes segment.index.bytes segment.jitter.ms segment.ms unclean.leader.election.enable See the Kafka documentation for full details on the topic configs.It is supported only in combination with -- create if --bootstrap-server option is used. --create Create a new topic. --delete Delete a topic --delete-config <String: name> A topic configuration override to be removed for an existing topic (see the list of configurations under the --config option). Not supported with the --bootstrap-server option. --describe List details for the given topics. --disable-rack-aware Disable rack aware replica assignment --exclude-internal exclude internal topics when running list or describe command. The internal topics will be listed by default --force Suppress console prompts --help Print usage information. --if-exists if set when altering or deleting or describing topics, the action will only execute if the topic exists. --if-not-exists if set when creating topics, the action will only execute if the topic does not already exist. --list List all available topics. --partitions <Integer: # of partitions> The number of partitions for the topic being created or altered (WARNING: If partitions are increased for a topic that has a key, the partition logic or ordering of the messages will be affected). If not supplied for create, defaults to the cluster default. --replica-assignment <String: A list of manual partition-to-broker broker_id_for_part1_replica1 : assignments for the topic being broker_id_for_part1_replica2 , created or altered. broker_id_for_part2_replica1 : broker_id_for_part2_replica2 , ...> --replication-factor <Integer: The replication factor for each replication factor> partition in the topic being created. If not supplied, defaults to the cluster default. --topic <String: topic> The topic to create, alter, describe or delete. It also accepts a regular expression, except for --create option. Put topic name in double quotes and use the '\' prefix to escape regular expression symbols; e. g. "test\.topic". --topics-with-overrides if set when describing topics, only show topics that have overridden configs --unavailable-partitions if set when describing topics, only show partitions whose leader is not available --under-min-isr-partitions if set when describing topics, only show partitions whose isr count is less than the configured minimum. Not supported with the --zookeeper option. --under-replicated-partitions if set when describing topics, only show under replicated partitions --version Display Kafka version. --zookeeper <String: hosts> DEPRECATED, The connection string for the zookeeper connection in the form host:port. Multiple hosts can be given to allow fail-over. localhost:kafka_2.13-2.6.0 gaoxinfu$

创建topic以及zk中的变化查看

创建topic

命令 bin/kafka-topics.sh --create --topic quickstart-events --bootstrap-server localhost:9092 命令解析 --create： 指定创建topic动作 --topic：指定新建topic的名称 --bootstrap-server:服务地址和端口

新开一个客户端

localhost:kafka_2.13-2.6.0 gaoxinfu$ pwd /Users/gaoxinfu/using/kafka_2.13-2.6.0 localhost:kafka_2.13-2.6.0 gaoxinfu$ bin/kafka-topics.sh --create --topic quickstart-events --bootstrap-server localhost:9092 Created topic quickstart-events. localhost:kafka_2.13-2.6.0 gaoxinfu$

zk中的变化查看

客户端发布者实时生成对应topic的事件(或者称之为消息内容)

localhost:kafka_2.13-2.6.0 gaoxinfu$ bin/kafka-console-producer.sh --topic quickstart-events --bootstrap-server localhost:9092 >这是我第一个事件 >这是我第二个事件 >

输入上面的命令，回车之后，会需要我们输入对应的消息内容 这里注意下，为了实时能够看到，订阅上面topic消费者可以实时接收到消息内容，我们在进行发布者生成消息之前，建议先打开消费者客户端

客户端消费者实时订阅对应topic的事件(或者称之为消息内容)

localhost:kafka_2.13-2.6.0 gaoxinfu$ bin/kafka-console-consumer.sh --topic quickstart-events --from-beginning --bootstrap-server localhost:9092 这是我第一个事件 这是我第二个事件
