ops

1. 连接到zookeeper服务

[java2000_wl@localhost zookeeper-3]$ bin/zkCli.sh -server 127.0.0.1:2181

2. 使用ls命令查看当前zookeeper中包含的内容
[zk: 127.0.0.1:2181(CONNECTED) 1] ls /
[zookeeper]

3. 创建新的znode，使用create命令
[zk:127.0.0.1:2181(CONNECTED) 2] create /zk testData
Created /zk

4. 获取节点中的值 get命令
[zk:127.0.0.1:2181(CONNECTED) 4] get /zk
testData
cZxid = 0x700000008
ctime = Sat Mar 0923:01:24 CST 2013
mZxid = 0x700000008
mtime = Sat Mar 0923:01:24 CST 2013
pZxid = 0x700000008
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 8
numChildren = 0

5. 使用set命令来对znode关联的字符串进行设置
[zk: 127.0.0.1:2181(CONNECTED) 5] set /zk mydata
cZxid = 0x700000008
ctime = Sat Mar 09 23:01:24 CST 2013
mZxid = 0x700000009
mtime = Sat Mar 09 23:06:03 CST 2013
pZxid = 0x700000008
cversion = 0
dataVersion = 1
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 6
numChildren = 0

6. 删除znode节点

[zk: 127.0.0.1:2181(CONNECTED) 7]delete /zk
