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
