docker-compose启动的tomcat无法远程连接jmx

最近想学习下java GC优化,就用了一下VisualVM,在远程服务器启动了一个非docker的tomcat,很顺利的就连接了,但是用docker-compose启动的服务却

怎么也连不上,一定是docker的锅.

最终找到了解决方法,在这里 https://forums.docker.com/t/enable-jmx-rmi-access-to-a-docker-container/625

这篇文章中最重要的一句话就是

In my case, I am working with docker-compose please DON FORGET to expose the SAME PORT 6001 in the remote docker host (it won't work if you expose in another port differently that jmxremote.port and jmxremote.rmi.port):

一句话概括就是: docker-compose暴露的端口要跟jmx的端口一样

好了,问题解决,下面写出tomcat配置jmx的方法:

1. docker-compose.yml

web:

  image: "registry.xxxxxx.com/msgbox/base_tomcat:tomcat7.42_jdk8u40"

  ports:

   - :

   - :

   - :

  volumes:

   - ./confs:/data1/confs

   - ./web/webapps:/data1/xxx/webapps

   - ./authconfs:/data1/authconfs

   - ./web/logs:/data1/xxx/logs

  environment:

   - NAME_CONF=test-yf=/data1/xxx/bin/./

   - RUN_COMMAND=catalina.sh jpda run

   - JMX_PORT=

   - JMX_HOST=10.77.6.164

   - CATALINA_HEAP=-server -Xmx768m -Xmn100m -Xms768m

  links:

    - kafka

2. setenv.sh

if [[ ! -z "$JMX_PORT" ]]; then

    if [ -z "$JMX_HOST" ]; then

        JMX_HOST=$(hostname -i)

    fi

    CATALINA_EXTRA="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=${JMX_PORT} -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=true -Dcom.sun.management.jmxremote.password.file=../conf/jmxremote.password -Dcom.sun.management.jmxremote.access.file=../conf/jmxremote.access -Djava.rmi.server.hostname=${JMX_HOST} -Dcom.sun.management.jmxremote.rmi.port=${JMX_PORT}"

fi

完成
