测试 kafka
新建一个名字为 test 的 topic
/kafka-topics.sh –create –zookeeper 192.168.1.70:2181 –replication-factor 1 –partitions 1 –topic test
查看 kafka 中的 topic
./kafka-topics.sh –list –zookeeper 192.168.1.70:2181
往 kafka topic 为 test 中 生产消息
./kafka-console-producer.sh –broker-list 192.168.1.70:9092 –topic test
在 kafka topic 为 test 中 消费消息
bin/kafka-console-consumer.sh –bootstrap-server 192.168.1.70:9092 –topic test –from-beginning
生产的消息，消费那边接受到即是 ok 的
