**1. 客户端连接**

$ zkCli -server 127.0.0.1:2181
    Connecting to 127.0.0.1:2181
    Welcome to ZooKeeper!
    JLine support is enabled
    
    WATCHER::
    
    WatchedEvent state:SyncConnected type:None path:null
    [zk: 127.0.0.1:2181(CONNECTED) 0]

**2. 查看帮助文件**

[zk: 127.0.0.1:2181(CONNECTED) 0] help
    ZooKeeper -server host:port cmd args
    	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

**3. 列出根节点目录**

[zk: 127.0.0.1:2181(CONNECTED) 1] ls /
    [dubbo, registry, zookeeper]

**4. 查看根节点目录内容**

[zk: 127.0.0.1:2181(CONNECTED) 3] get /zookeeper
    
    cZxid = 0x0
    ctime = Thu Jan 01 08:00:00 CST 1970
    mZxid = 0x0
    mtime = Thu Jan 01 08:00:00 CST 1970
    pZxid = 0x0
    cversion = -1
    dataVersion = 0
    aclVersion = 0
    ephemeralOwner = 0x0
    dataLength = 0
    numChildren = 1

**5. 创建节点**

[zk: 127.0.0.1:2181(CONNECTED) 7] create /test 111
    Created /test
    [zk: 127.0.0.1:2181(CONNECTED) 8] get /test
    111
    cZxid = 0x151db
    ctime = Sun May 27 16:17:49 CST 2018
    mZxid = 0x151db
    mtime = Sun May 27 16:17:49 CST 2018
    pZxid = 0x151db
    cversion = 0
    dataVersion = 0
    aclVersion = 0
    ephemeralOwner = 0x0
    dataLength = 3
    numChildren = 0

[zk: 127.0.0.1:2181(CONNECTED) 11] create /test/test11 ssss
    Created /test/test11
    [zk: 127.0.0.1:2181(CONNECTED) 12] get /test/test11
    ssss
    cZxid = 0x151dd
    ctime = Sun May 27 16:19:21 CST 2018
    mZxid = 0x151dd
    mtime = Sun May 27 16:19:21 CST 2018
    pZxid = 0x151dd
    cversion = 0
    dataVersion = 0
    aclVersion = 0
    ephemeralOwner = 0x0
    dataLength = 4
    numChildren = 0

**6. 断开客户端连接**

[zk: 127.0.0.1:2181(CONNECTED) 13] quit
    Quitting...

**Tips:**

在使用get命令获取内容时，如果你不知道这个目录下有什么，你可以直接按Tab键进行提示。

如我敲了**get /dubbo/**命令，然后按下Tab，就会有一堆提示

[zk: 127.0.0.1:2182(CONNECTED) 6] get /dubbo/
    
    org.provider.business.StudyPlanProvider             org.provider.DebtRepaymentLogProvider
    org.provider.shop.ComplainProvider           		org.provider.MediaLabelsProvider
    org.provider.pay.UnionpayProvider                   org.provider.wechat.TWxWxjrProvider
    org.provider.AdOrderRequestsProvider         		org.provider.shop.ShopCartProvider
    org.provider.sys.SysUserDetailProvider              org.provider.InvoiceProvider
