Cassandra nodetool：连接拒绝主机：172.24.0.10

当我使用Cassandra的nodetool来查看远程主机的环（使用IP地址）时，它给出了以下错误，如何使其工作？顺便说一句 - 我可以ping通该主机使用IP地址。Cassandra nodetool：连接拒绝主机：172.24.0.10

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

Schildmeijer您好，我运行命令后，它说：根@服务器A：〜/卡桑德拉＃java的-Dcom.sun.management.jmxremote .port = 8080 错误：必须限制密码文件读取访问权限：/usr/lib/jvm/java-6-openjdk/jre/lib/management/jmxremote.password 对不起，我是linux和java的新手。 – 2010-10-08 23:07:09
