[zk: localhost:2181(CONNECTED) 1] create /zk-test/book 233
Created /zk-test/book
# 获取节点数据
[zk: localhost:2181(CONNECTED) 2] get /zk-test
123
# 查看所有节点
[zk: localhost:2181(CONNECTED) 3] ls /
[zk-test, zookeeper]
# 查看子节点
[zk: localhost:2181(CONNECTED) 5] ls /zk-test
[book]
# 修改节点
[zk: localhost:2181(CONNECTED) 6] set /zk-test 456
# 修改子节点
[zk: localhost:2181(CONNECTED) 7] set /zk-test/book 789
[zk: localhost:2181(CONNECTED) 8] get /zk-test
456
[zk: localhost:2181(CONNECTED) 9] get /zk-test/book
789
