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： $echo ruok | nc 127.0.0.1 3355 Imok$
