Kafka zookeeper-shell.sh

bin/zookeeper-shell.sh作用是连接zookeeper,并通过命令查询注册的信息,本质上就是zookeeper的语法。
bin/zookeeper-shell.sh zookeeper_host:port[/path] [args…]
args参数类型如下

stat path [watch]
set path data [version]
ls path [watch]
delquota [-n|-b] path
ls2 path [watch]
setAcl path acl
setquota -n|-b val path
history
redo cmdno
printwatches on|off
delete path [version]
sync path
listquota path
rmr path
get path [watch]
create [-s] [-e] path data acl
addauth scheme auth
quit
getAcl path
close
connect host:port       

1.连接zookeeper

bin/zookeeper-shell.sh 127.0.0.1:2181

2.ls path
查看节点列表, ls path 和 ls2 path 两个命令,后者是前者的增强,不仅可以查看指定路径下的所有节点,还可以查看当前节点的信息。

ls /
[cluster, controller, controller_epoch, brokers, zookeeper, admin, isr_change_notification, consumers, log_dir_event_notification, latest_producer_id_block, config]

ls /brokers/ids
[0]

ls /brokers/topics
[topic1]


3 get path
获取某子节点的值

get /brokers/ids/0

aclVersion 节点的 ACL 的更改次数
ephemeralOwner 如果节点是临时节点,则表示创建该节点的会话的 SessionID;如果节点是持久节点,则该属性值为 0
dataLength 数据内容的长度
