zookeeper的使用

		zookeeper的使用 
zookeeper启动之后，不需要执行命令，只需查看批准的状况，命令如下：

１、ruok - The server will respond with imok if it is running. Otherwise it will not respond at all.

２、kill - When issued from the local machine, the server will shut down.

３、dump - Lists the outstanding sessions and ephemeral nodes. This only works on the leader.

４、stat - Lists statistics about performance and connected clients.

例如：

$echo ruok | nc 127.0.0.1 3355

Imok$
