# create persistent nodes

Create / path / data acl

# create a sequential node

Create-s / path / data

# create a temporary node

Create-e / path / data

# create a child node, just like creating a root node

Create / parent/path/subnode/path / data

# set value

Set / path / data [version]

# get data: (it returns the associated data of znode and the metadata of specified znode)

Get / path

Note: to access the sequential node, you must enter the full path to the znode.

# Monitoring (the monitor will display a notification when the child data of the specified znode or znode changes) the listener will only take effect once

Get / path [watch]

# remove the node, remove the specified znode and recursively all its child nodes

Rmr / path

# Delete a node. If a child node exists, it cannot be deleted

Delete / path [version]

# list children, and you can only view all child nodes at the first level under the specified node

Ls / path [watch]

. View the current node data and see data such as the number of updates

Ls2 / path [watch]

# check status

Stat / path start ZooKeeper server $bin/zkServer.sh start stop ZooKeeper server $bin/zkServer.sh stop view ZK service status $bin/zkServer.sh status restart ZK service $bin/zkServer.sh restart start CLI$ bin/zkCli.sh this is the end of the study on "what are the common zookeeper commands".
