- connecthost:port
- getpath [watch]
- lspath [watch]
- setpath data [version]
- rmrpath
- delquota[-n|-b] path
- quit
- printwatcheson|off
- create[-s] [-e] path data acl
- statpath [watch]
- close
- ls2path [watch]
- history
- listquotapath
- setAclpath acl
- getAclpath
- syncpath
- redocmdno
- addauthscheme auth
- deletepath [version]
- setquota-n|-b val path
首先，看看列表命令，如下：
点击(此处)折叠或打开
- [zk: 127.0.0.1:2181(CONNECTED) 6] ls /
- [zookeeper]
点击(此处)折叠或打开
- [zk: 127.0.0.1:2181(CONNECTED) 6] create/zk_test my_data
- Created /zk_test
点击(此处)折叠或打开
- [zk: 127.0.0.1:2181(CONNECTED) 6] ls /
- [zookeeper, zk_test]
下面，我们使用get命令来验证此znode节点相关的数据，如下：

- [zk: 127.0.0.1:2181(CONNECTED) 7] get/zk_test
- my_data
- cZxid = 0x4
- ctime = Fri May 02 08:28:40 UTC 2014
- mZxid = 0x4
- mtime = Fri May 02 08:28:40 UTC 2014
- pZxid = 0x4
- cversion = 0
- dataVersion = 0
- aclVersion = 0
- ephemeralOwner = 0x0
- dataLength = 7
- numChildren = 0
点击(此处)折叠或打开
- [zk: 127.0.0.1:2181(CONNECTED) 8] set/zk_test junk
- cZxid = 0x4
- ctime = Fri May 02 08:28:40 UTC 2014
- mZxid = 0x5
- mtime = Fri May 02 08:34:32 UTC 2014

- [zk: 127.0.0.1:2181(CONNECTED) 11] ls /
- [zookeeper]
点击(此处)折叠或打开
- [zk: 127.0.0.1:2181(CONNECTED) 12] quit
- Quitting...
