Question

我试图在Mac OSX 10.10上运行Cassandra。我已经安装了dsc-cassandra-2.1.9。一些cassandra.yaml设置是： listen_address：127.0.0.1 rpc_address：127.0.0.1 rpc_port：9160

然而，当我启动cassandra时，它失败了：

$ ./bin/cassandra 
...

有人可以帮忙解决这个问题吗？

按照以下答案中的建议设置JVM_OPTS =“$ JVM_OPTS -Djava.rmi.server.hostname = 127.0.0.1”之后，cassandra似乎正在运行，但是nodetool似乎没有报告正确的状态：

Answer 1

面临同样的错误，以下是解决方案。

停止cassandra ps -ef | grep cassandra | grep -v grep | awk'{print $ 2}'| xargs kill -9

在cassandra-env.sh中修改以下内容： -

取消注释JVM_OPTS =“$ JVM_OPTS -Djava.rmi.server.hostname =”并更改为 JVM_OPTS =“$ JVM_OPTS -Djava.rmi.server.hostname = 127.0.0.1”
将LOCAL_JMX = yes更改为LOCAL_JMX =否
将true更改为false JVM_OPTS =“$ JVM_OPTS -Dcom.sun.management.jmxremote.authenticate = false”

如果仍然看到任何问题，请检查JMX_PORT =“XXX”指定的端口是否被占用。或者只需将其更改为JMX_PORT =“9909”并重新启动cassandra。

Answer 2

确认端口 7199 上没有其他任何内容正在运行。你可以，例如通过修改 cassandra-env.sh 中的 JMX_PORT ，也可以为JMX使用不同的端口。
查看 cassandra-env.sh 并尝试修改以下行：

JVM_OPTS="$JVM_OPTS -Djava.rmi.server.hostname=<public name>"
