zookeeper命令操作

查看目录

[zk: localhost:2181(CONNECTED) 0] ls /
[zookeeper, example1, example2]

创建节点

创建一个test1节点以及与它关联的字符串：

[zk: localhost:2181(CONNECTED) 0] create /test1 myData1
Created /test1

　

获取刚创建的节点上的字符串

[zk: localhost:2181(CONNECTED) 3] get /test1
myData1
cZxid = 0x2b43
ctime = Thu Oct 22 11:57:47 CST 2015
mZxid = 0x2b43
mtime = Thu Oct 22 11:57:47 CST 2015
pZxid = 0x2b43
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 7
numChildren = 0

　　

通过set修改节点上的字符串

[zk: localhost:2181(CONNECTED) 4] set /test1 myData2
cZxid = 0x2b43
ctime = Thu Oct 22 11:57:47 CST 2015
mZxid = 0x2b44
mtime = Thu Oct 22 12:01:19 CST 2015
pZxid = 0x2b43
cversion = 0
dataVersion = 1
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 7
numChildren = 0
[zk: localhost:2181(CONNECTED) 5] get /test1
myData2
cZxid = 0x2b43
ctime = Thu Oct 22 11:57:47 CST 2015
mZxid = 0x2b44
mtime = Thu Oct 22 12:01:19 CST 2015
pZxid = 0x2b43
cversion = 0
dataVersion = 1
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 7
numChildren = 0

　　

删除节点

[zk: localhost:2181(CONNECTED) 6] delete /test1
[zk: localhost:2181(CONNECTED) 7] ls /
