java - Cassandra docker - 无法通过 JMX 连接

Question

我很难通过 JMX 连接到 docker 容器内的 Cassandra。我在 AWS 中运行(这意味着我获得了 NATted IP)。以下是我尝试过的方法:

1. 创建 jmxremote.password 文件
2. 添加了 jmxremote.password 文件以启用 jmx 连接。我从中创建图像的 Dockerfile:

FROM cassandra:latest

COPY ./jmxremote.password /etc/cassandra/jmxremote.password

RUN chmod 400 /etc/cassandra/jmxremote.password

COPY ./jmxremote.password /etc/java-8-openjdk/management/jmxremote.password

1. 我使用上面的 docker 文件构建了镜像
2. 运行容器:

   docker run -P -d -e "JVM_OPTS=-Djava.rmi.server.hostname=10.0.1.12" -e "LOCAL_JMX=no" -e

这会引发以下异常:

java.rmi.ConnectException: Connection refused to host: 10.0.1.12; nested exception is:

1. 我尝试将 cassandra.yaml 文件中的 listen_address 设置为我的主机 IP (10.0.1.12)，因为这默认设置为 docker IP。同样的结果
2. 我也尝试在启动容器时设置环境变量“CASSANDRA_START_RPC=true”，但我遇到了同样的问题

有人可以就过去几天完全阻止我的这个问题提供指示或帮助吗？提前感谢您抽出时间分享您的知识。

干杯，苏朵儿

我像这样关闭了 jmx 身份验证:

jetty 文件:

FROM cassandra

RUN sed -i 's/JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.authenticate=true"/JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.authenticate=false"/g' /etc/cassandra/cassandra-env.sh

RUN sed -i '/password/d' /etc/cassandra/cassandra-env.sh

docker-compose.yml:

environment:
    - LOCAL_JMX=no
    - JVM_EXTRA_OPTS=-Djava.rmi.server.hostname=127.0.0.1
