zookeeper基本命令行操作

Posted 2021-10-02 暴躁的程序猿啊

Zookeeper客户端命令行操作

zookeeper节点类型(持久/短暂/有序号/无序号)

持久：客户端和服务端断开连接后 创建的节点不删除

创建持久节点 create /yingxiong "daomei"

创建带序号的持久节点

[zk: localhost:2181(CONNECTED) 14] create  -s  /yinxiong   "feileier"
Created /yinxiong0000000001

短暂：客户端和服务端断开连接后，创建的节点自己删除

zk: localhost:2181(CONNECTED) 5] create -e /yingxiong "zhumei"
zk: localhost:2181(CONNECTED) 5] create -e -s /yingxiong "zhumei"  带序号的

监听节点值的变化

get -w  /yingxiong

注意 ：注册一次生效一次 想多次生效就要注册多次

节点的删除与查看

删除节点
delete /yingxiong/lianmeng 
递归删除节点
deleteall /yingxiong/lianmeng

[zk: localhost:2181(CONNECTED) 9] deleteall /yingxiong
[zk: localhost:2181(CONNECTED) 10] ls /yingxiong
Node does not exist: /yingxiong

查看节点状态
stat /yingxiong

[zk: localhost:2181(CONNECTED) 16] stat /yinxiong0000000001
