一、服务端命令
1、启动Zookeeper服务命令
zkServer.sh start
执行结果：
ZooKeeper JMX enabled by default
Using config: /Users/davis/soft/zookeeper-3.6.3/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
2、查看Zookeeper状态命令
zkServer.sh status
执行结果：
ZooKeeper JMX enabled by default
Using config: /Users/davis/soft/zookeeper-3.6.3/bin/../conf/zoo.cfg
Client port found: 2181. Client address: localhost. Client SSL: false.
Mode: standalone
3、停止Zookeeper服务命令
zkServer.sh start
4、启动Zookeeper客户端命令
zkCli.sh -server 127.0.0.1:1281
执行结果：

二、客户端命令
执行客户端命令前，首先要执行「启动Zookeeper客户端命令」启动客户端。
1、查看帮助
help
执行结果：
ZooKeeper -server host:port -client-configuration properties-file cmd args
addWatch [-m mode] path
addauth scheme auth
close
config [-c] [-w] [-s]
connect host:port
create [-s] [-e] [-c] [-t ttl] path [data] [acl]

Command not found: Command not found help
2、查看当前znode所包含的内容
ls /
执行结果：
[username, zookeeper]
3、创建znode
create /username davis
执行结果：
Created /username
4、创建短暂znode
create -e /duanzan davis-duanzan
执行结果：
Created /duanzan
5、创建带序号znode
create -s /xuhao davis-xuhao
执行结果：
Created /xuhao0000000003
6、创建短暂带序号znode
create -e -s /duanzanxuhao davis-duanzanxuhao
执行结果：
Created /duanzanxuhao0000000004
7、获取znode数据
get /username
执行结果：
davis
8、修改znode数据
set /username davis-1
9、删除znode
delete /username
10、查看znode状态
stat /
执行结果：
cZxid = 0x0
ctime = Thu Jan 01 08:00:00 CST 1970
mZxid = 0x0
mtime = Thu Jan 01 08:00:00 CST 1970
pZxid = 0xd
cversion = 6
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x0
dataLength = 0
numChildren = 4
