Zookeeper（四）简单操作
1.连接到zookeeper服务
$ 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
ls /
3.创建新的znode，使用create命令
create /zk testData
Created /zk
4.获取节点中的值get命令
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
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
delete /zk
