以下是几个zookeeper客户端用的命令，不只kafka，其他任何注册到zookeeper的服务都可以使用这些命令。文章源自小柒网-https://www.yangxingzhen.cn/6692.html

1、ls文章源自小柒网-https://www.yangxingzhen.cn/6692.html

ls会显示该节点下的子节点信息文章源自小柒网-https://www.yangxingzhen.cn/6692.html

比如：ls /文章源自小柒网-https://www.yangxingzhen.cn/6692.html

[zk: localhost:2181(CONNECTED) 1] ls /
[dubbo, log_dir_event_notification, isr_change_notification, zookeeper, admin, consumers, cluster, config, latest_producer_id_block, controller, brokers, controller_epoch]

#显示zookeeper根目录下的子节点，其中kafka的broker在zookeeper根目录注册了brokers节点文章源自小柒网-https://www.yangxingzhen.cn/6692.html

比如：ls /brokers/topics/lockcar_loction/partitions

[zk: localhost:2181(CONNECTED) 2] ls /brokers/topics/lockcar_loction/partitions
[1, 0]

#显示lockcar_loction这个topic下的partitions的子节点

2、get

get命令会显示该节点的节点数据内容和属性信息

比如：get /brokers/topics/lockcar_loction

[zk: localhost:2181(CONNECTED) 2] get /brokers/topics/lockcar_loction
{"version":1,"partitions":{"1":[1],"0":[3]}}
cZxid = 0x5000000cf
ctime = Wed Apr 08 09:12:12 CST 2020
mZxid = 0x5000000cf
mtime = Wed Apr 08 09:12:12 CST 2020
pZxid = 0x5000000d2
cversion = 1
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 44
numChildren = 1

#显示lockcar_loction这个topic的节点数据内容和属性信息。

#第一行大括号里面就是节点的数据内容，创建topic时候的定义的topic级别配置会被记录在这里

3、ls2

ls2命令会显示该节点的子节点信息和属性信息

比如：ls2 /brokers/topics/lockcar_loction

[zk: localhost:2181(CONNECTED) 4] ls2 /brokers/topics/lockcar_loction
[partitions]
cZxid = 0x5000000cf
ctime = Wed Apr 08 09:12:12 CST 2020
mZxid = 0x5000000cf
mtime = Wed Apr 08 09:12:12 CST 2020
pZxid = 0x5000000d2
cversion = 1
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 44
numChildren = 1

#显示lockcar_loction这个topic的子节点和属性信息。

#第一行中括号里的是子节点。
