zookeepeer使用zkCli.sh命令

一、连接服务器端

 [root@sxl132 zookeepeer]# ./bin/zkCli.sh -server 192.168.116.144:2181
 Connecting to 192.168.116.144:
 -- ::, [myid:] - INFO  [main:Environment@] - Client environment:zookeeper.version=3.4.-37e277162d567b55a07d1755f0b31c32e93c01a0, built on // : GMT

 。。。。。。。。。。。。。。。。。。。。。。。。。。
 6.144/192.168.116.144:, sessionid = 0x4000004a4240000, negotiated timeout = 

 WATCHER::

 WatchedEvent state:SyncConnected type:None path:null

二、使用zkCli.sh的相关指令

1、查看相关命令

 [zk: 192.168.116.144:(CONNECTED) ] h
 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

2、查看目录结构

 [zk: 192.168.116.144:(CONNECTED) ] ls /  
 [zookeeper]
 [zk: 192.168.116.144:(CONNECTED) ] ls2 /
 [zookeeper]
 cZxid = 0x0
 ctime = Wed Dec  :: PST
 mZxid = 0x0
 mtime = Wed Dec  :: PST
 pZxid = 0x0
 cversion = -
 dataVersion =
 aclVersion =
 ephemeralOwner = 0x0
 dataLength =
 numChildren = 

3、创建节点和节点数据

 [zk: 192.168.116.144:(CONNECTED) ] create /root root_data
 Created /root
 [zk: 192.168.116.144:(CONNECTED) ] ls /
 [zookeeper, root]

4、查看节点及节点的数据信息

 [zk: 192.168.116.144:(CONNECTED) ] get /root
 root_data
 cZxid = 0xa00000002
 ctime = Thu Jan  :: PST
 mZxid = 0xa00000002
 mtime = Thu Jan  :: PST
 pZxid = 0xa00000002
 cversion =
 dataVersion =
 aclVersion =
 ephemeralOwner = 0x0
 dataLength =
 numChildren = 

5、修改节点数据

 [zk: 192.168.116.144:(CONNECTED) ] set /root ROOT_DATA
 cZxid = 0xa00000002
 ctime = Thu Jan  :: PST
 mZxid = 0xa00000003
 mtime = Thu Jan  :: PST
 pZxid = 0xa00000002
 cversion =
 dataVersion =
 aclVersion =
 ephemeralOwner = 0x0
 dataLength =
 numChildren =
 [zk: 192.168.116.144:(CONNECTED) ] get /root
 ROOT_DATA
 cZxid = 0xa00000002
 ctime = Thu Jan  :: PST
 mZxid = 0xa00000003
 mtime = Thu Jan  :: PST
 pZxid = 0xa00000002
 cversion =
 dataVersion =
 aclVersion =
 ephemeralOwner = 0x0
 dataLength =
 numChildren = 

6、删除节点

 [zk: 192.168.116.144:(CONNECTED) ] delete /root
 [zk: 192.168.116.144:(CONNECTED) ] ls /
 [zookeeper]

其他的命令，童鞋们可以自己去尝试。
