当我使用 Cassandra 的 nodetool 查看远程主机的环(使用 IP 地址)时，它给出以下错误，如何使它工作？ 顺便说一句 - 我可以使用 IP 地址 ping 该主机。
root@ServerA:~/cassandra# bin/nodetool -h 172.24.0.10 ring

您需要启用远程 JMX:
To enable monitoring and management from remote systems, set this system property when you start the JVM: com.sun.management.jmxremote.port=portNum
