# ./bin/zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /conf/zoo.cfg
Client port found: 2181. Client address: localhost. Client SSL: false.
Mode: leader

# 如果你已经成功启动kafka集群，可以使用以下命令来查看是否有数据
[zk: localhost:2181(CONNECTED) 1] ls /
[admin, brokers, cluster, config, consumers, controller, controller_epoch, feature, isr_change_notification, latest_producer_id_block, log_dir_event_notification, zookeeper]
[zk: localhost:2181(CONNECTED) 0] ls /brokers/ids
[1, 2, 3]
