执行/opt/apache-zookeeper-3.6.3-bin-bcm/bin/zkCli.sh -server localhost:2182登录zookeeper。

执行get /zookeeper/config查询当前集群节点信息，查看到ceph1-ceph5 5个节点的配置信息。

       
            [zk: localhost:2182(CONNECTED) 0] get /zookeeper/config 
server.80=ceph1:2889:3889:participant;0.0.0.0:2182
server.100=ceph3:2889:3889:participant;0.0.0.0:2182
server.4=ceph4:2889:3889:participant;0.0.0.0:2182
server.5=ceph5:2889:3889:participant;0.0.0.0:2182
server.90=ceph2:2889:3889:participant;0.0.0.0:2182
