2、添加并查看节点数据

　　2.1添加根节点"node_1"，节点数据为"data1"

[zk: 127.0.0.1:2181(CONNECTED) 1] ls /
[zookeeper]
[zk: 127.0.0.1:2181(CONNECTED) 2] create /node_1 data1

　　2.3 添加临时节点node1.2，重新连接后将无法获取对应的节点及其数据

4、删除节点

4.1 若当前节点没有子节点，执行delete /path

[zk: 127.0.0.1:2181(CONNECTED) 4] delete /node_2/node2.1

4.2 若当前节点有子节点，执行rmr /path

[zk: 127.0.0.1:2181(CONNECTED) 5] rmr /node_1
[zk: 127.0.0.1:2181(CONNECTED) 6] rmr /node_2
