安装zookeeper

	(一)安装zookeeper
(1)tar zxf zookeeper-3.3.3.tar.gz

(2)mv zookeeper-3.3.3 /usr/local/zookeeper

(3)cd /usr/local/zookeeper/conf/

(4)cp zoo_sample.cfg zoo.cfg

(5)vim zoo.cfg
修改的内容
dataDir=/usr/local/zookeeper/zookeeper-data
data
LogDir=/usr/local/zookeeper/logs
clientPort=2181
server.1=master:2888:3888

server.2=slave1:2888:3888

server.3=slave2:2888:3888

server.4=slave3:2888:3888

server.5=slave4:2888:3888


(6)	mkdir /usr/local/zookeeper/zookeeper-data
data
	mkdir /usr/local/zookeeper/logs

 (7)	在/usr/local/zookeeper/zookeeper-data
data目录下创建文件,命名为myid

(8)	编辑“myid”文件并在对应的IP的机器上输入对应的编号。如在master上,“myid”文件内容就是1,
在slave1上,内容就是2

(9)在	(1)cd /etc/profile.d
	(2)vim zookeeper.sh
#keeper path
ZOOKEEPER=/usr/local/zookeeper
PATH=$PATH:$ZOOKEEPER/bin
export PATH
	(3)赋权,使之可执行chmod 755 ./*
			执行./zookeeper.sh


(10)将/usr/local/zookeeper目录分别拷贝到192.168.10.197和192.168.10.198等四台机子下,同时修改对应的“myid”文件内容。
	

		(二)启动zookeeper
(1)在五台机器上分别执行shell脚本。
無限定誰先誰後,但三台電腦間執行此指令的間隔不宜過久(因為有設定timeout時間)
没有出错信息,则成功启动.

/usr/local/zookeeper/bin/zkServer.sh start

(2)启动客户端脚本

zkCli.sh -server 192.168.10.168:2181

(3)执行完成之后输入“jps”命令查看

jps

(4)通过输入“/usr/local/zookeeper/bin/zkServer.sh status”检查是否启动

(5)通过在控制台输入命令检查集群zookeeper启动状态。

命令如“echo ruok | nc 192.168.10.168 2181”,

控制台输出“imok”


	(三)执行测试
(1)cd /usr/local/zookeeper 

(2)bin/zkCli.sh -server 192.168.10.196:2181

(3)
[zk: 192.168.10.196:2181(CONNECTED) 0] create /mytest test
Created /mytest
[zk: 192.168.10.196:2181(CONNECTED) 1] ls /
[mytest, zookeeper]
[zk: 192.168.10.196:2181(CONNECTED) 2] get /mytest
test
cZxid = 0x200000006
ctime = Thu Nov 10 12:58:01 CST 2011
mZxid = 0x200000006
mtime = Thu Nov 10 12:58:01 CST 2011
pZxid = 0x200000006
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 4
numChildren = 0
[zk: 192.168.10.196:2181(CONNECTED) 3] 


在其他机器上查询:
(1)cd /usr/local/zookeeper

(2)bin/zkCli.sh -server 192.168.10.198:2181

(3)
[zk: 192.168.10.198:2181(CONNECTED) 1] ls /
[mytest, zookeeper]
[zk: 192.168.10.198:2181(CONNECTED) 2] ls /mytest
[]
[zk: 192.168.10.198:2181(CONNECTED) 3] get /mytest
test
cZxid = 0x200000006
ctime = Thu Nov 10 12:58:01 CST 2011
mZxid = 0x200000006
mtime = Thu Nov 10 12:58:01 CST 2011
pZxid = 0x200000006
cversion = 0
