一、服務端命令

1、啟動Zookeeper服務命令

zkServer.sh start

執行結果：

ZooKeeper JMX enabled by default Using config: /Users/davis/soft/zookeeper-3.6.3/bin/../conf/zoo.cfg Starting zookeeper ... STARTED

2、查看Zookeeper狀態命令

zkServer.sh status

執行結果：

ZooKeeper JMX enabled by default Using config: /Users/davis/soft/zookeeper-3.6.3/bin/../conf/zoo.cfg Client port found: 2181. Client address: localhost. Client SSL: false. Mode: standalone

3、停止Zookeeper服務命令

zkServer.sh start

4、啟動Zookeeper客戶端命令

zkCli.sh -server 127.0.0.1:1281

執行結果：

二、客戶端命令

執行客戶端命令前，首先要執行「啟動Zookeeper客戶端命令」啟動客戶端。

1、查看幫助

help

執行結果：

ZooKeeper -server host:port -client-configuration properties-file cmd argsaddWatch [-m mode] path # optional mode is one of [PERSISTENT, PERSISTENT_RECURSIVE] - default is PERSISTENT_RECURSIVEaddauth scheme authcloseconfig [-c] [-w] [-s]connect host:portcreate [-s] [-e] [-c] [-t ttl] path [data] [acl]delete [-v version] pathdeleteall path [-b batch size]delquota [-n|-b] pathget [-s] [-w] pathgetAcl [-s] pathgetAllChildrenNumber pathgetEphemerals pathhistorylistquota pathls [-s] [-w] [-R] pathprintwatches on|offquitreconfig [-s] [-v version] [[-file path] | [-members serverID=host:port1:port2;port3[,...]*]] | [-add serverId=host:port1:port2;port3[,...]]* [-remove serverId[,...]*]redo cmdnoremovewatches path [-c|-d|-a] [-l]set [-s] [-v version] path datasetAcl [-s] [-v version] [-R] path aclsetquota -n|-b val pathstat [-w] pathsync pathversion Command not found: Command not found help

2、查看當前znode所包含的內容

ls /

執行結果：

[username, zookeeper]

3、創建znode

create /username davis

執行結果：

Created /username

4、創建短暫znode

create -e /duanzan davis-duanzan

執行結果：

Created /duanzan

5、創建帶序號znode

create -s /xuhao davis-xuhao

執行結果：

Created /xuhao0000000003

6、創建短暫帶序號znode

create -e -s /duanzanxuhao davis-duanzanxuhao

執行結果：

Created /duanzanxuhao0000000004

7、獲取znode數據

get /username

執行結果：

davis

8、修改znode數據

set /username davis-1

9、刪除znode

delete /username

10、查看znode狀態

stat /

執行結果：

cZxid = 0x0 ctime = Thu Jan 01 08:00:00 CST 1970 mZxid = 0x0 mtime = Thu Jan 01 08:00:00 CST 1970 pZxid = 0xd cversion = 6 dataVersion = 0 aclVersion = 0 ephemeralOwner = 0x0 dataLength = 0 numChildren = 4
