下载解压到（我自己的）解压到 /usr/local 下

把名字改成 zookeeper

进入zookeeper目录下的conf目录，复制zoo_sample.cfg为zoo.cfg，并将内容修改如下（就是解压后的路径，其他的不用改了，这个路径一般与默认的不同，要改）

dataDir=/usr/local/zookeeper

tickTime：Zookeeper 服务器之间或客户端与服务器之间心跳的时间间隔。
dataDir：Zookeeper 保存数据的目录，默认情况下，Zookeeper 将写数据的日志文件也保存在这个目录里。
clientPort：Zookeeper 服务器监听端口，用来接受客户端的访问请求。

然后，

进入Zookeeper/bin目录

启动服务与查看服务状态：

root@kali:/usr/local/zookeeper/bin# ./zkServer.sh start
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
root@kali:/usr/local/zookeeper/bin# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Mode: standalone

打开客户端

$ ./zkCli.sh 或 $ ./zkCli.sh -server 127.0.0.1:2181

连接后可以

[zk: localhost:2181(CONNECTED) 3] ls / #查看节点
[zookeeper]
[zk: localhost:2181(CONNECTED) 4] create /mynode1 myvalue1 #建立节点
Created /mynode1
[zk: localhost:2181(CONNECTED) 5] create /mynode2 myvalue2
Created /mynode2
[zk: localhost:2181(CONNECTED) 6] ls /
[mynode1, mynode2, zookeeper]
[zk: localhost:2181(CONNECTED) 7] get /mynode1 #获取节点的值
