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

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

--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

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.

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
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
