无法在 Mac 上启动 Cassandra DSC - 启动本地 jmx 服务器时出错

Question

我正在尝试在我的 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： 听地址：127.0.0.1 rpc_address：127.0.0.1 rpc_port: 9160

但是当我启动 cassandra 时，它失败了：

$ ./bin/cassandra 
...

有人可以帮忙解决这个问题吗？

上述问题的更新 --

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

而且 cqlsh 似乎正在工作：

Answer 1

遇到同样的错误，下面是解决方法。

停止卡桑德拉 ps -ef | grep 卡桑德拉 | grep -v grep | awk '{打印 $2}' | xargs 杀死 -9

在 cassandra-env.sh 中修改以下内容：-

1. 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"

2. 将 LOCAL_JMX=yes 更改为 LOCAL_JMX=no

3. 将 true 更改为 false JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.authenticate=false"

如果您仍然看到任何问题，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

1. 验证端口 7199 上没有运行其他任何东西。你可以例如还可以通过修改 cassandra-env.sh 中的 JMX_PORT 为 JMX 使用不同的端口。

2. 查看 cassandra-env.sh 并尝试修改以下行：

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