/opt/kafka_2.9.1-0.8.2.1/bin/kafka-topics.sh --create --zookeeper 127.0.0.1:2181 --replication-factor 1 --partitions 100 --topic presencecapwap
2、修改topic
/opt/kafka_2.9.1-0.8.2.1/bin/kafka-topics.sh --zookeeper 127.0.0.1：2181 --alter --topic presencecapwap --config num.partitions=150
3、刪除topic
delete topic step:
#3-1、/opt/kafka_2.9.1-0.8.2.1/bin/kafka-topics.sh --zookeeper 127.0.0.1:2181 --delete --topic presencecapwap
#3-2、ps -def | grep kafka
kill pid
#3-3、cd /usr/lib/zookeeper
bin/zkCli.sh -server 127.0.0.1:2181
ls /
#3-4、rmr /admin/delete_topics/presencecapwap
rmr /config/topics/presencecapwap
rmr /brokers/topics/presencecapwap
#3-5、bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 100 --topic presencecapwap
4、查看topic
/opt/kafka_2.9.1-0.8.2.1/bin/kafka-topics.sh --list --zookeeper 127.0.0.1:2181
/opt/kafka_2.9.1-0.8.2.1/bin/kafka-topics.sh --describe --zookeeper 127.0.0.1:2181 --topic presencecapwap
5、kafka：producer-consumer
#5-1、producer：/opt/kafka_2.9.1-0.8.2.1/bin/kafka-console-producer.sh --broker-list hzmonitor30:9092 --topic presencecapwap
#5-2、consumer：/opt/kafka_2.9.1-0.8.2.1/bin/kafka-console-consumer.sh --zookeeper 127.0.0.1:2181 --topic presencecapwap --from-beginning
