zookeeper入門_二【筆記】

基本操作

1.啓動zookeeper

[root@ahui apache-zookeeper-3.5.5-bin]# bin/zkServer.sh start

2.進入zookeeper客戶端

[root@ahui apache-zookeeper-3.5.5-bin]# bin/zkCli.sh

3.創建 znode

[zk: localhost:2181(CONNECTED) 2] create /my_test testData
Created /my_test

4.查看znode信息

[zk: localhost:2181(CONNECTED) 3] get /my_test
testData

5.修改znode數據

[zk: localhost:2181(CONNECTED) 4] set /my_test testDataV2
[zk: localhost:2181(CONNECTED) 5] get /my_test
testDataV2

6.創建znode

[zk: localhost:2181(CONNECTED) 6] create /my_test/tester1 testData
Created /my_test/tester1

7.列出子znode

[zk: localhost:2181(CONNECTED) 7] ls /my_test
[tester1]

8.刪除 znode

不能直接刪除 否則報錯
[zk: localhost:2181(CONNECTED) 8] delete /my_test
Node not empty: /my_test

9.刪除整個znode

[zk: localhost:2181(CONNECTED) 9] delete /my_test/tester1
