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

执行结果：

[username, zookeeper]
1

3、创建znode

create /username davis
1

执行结果：

Created /username
1

4、创建短暂znode

create -e /duanzan davis-duanzan
1

执行结果：

Created /duanzan
1

5、创建带序号znode

create -s /xuhao davis-xuhao
1

执行结果：

Created /xuhao0000000003
