JMX获取Activemq的详细信息

Apache ActiveMQ 自带监控管理界面，浏览器activemq启动ip：8161即可，初始用户名密码为admin，admin；本文是想解决将activemq的监控添加到自己的项目中。

然后，编辑activemq为程序开启的入口，需要添加一些配置:

    ACTIVEMQ_CONF="/root/apache-activemq-5.14.0/conf"
    ACTIVEMQ_SUNJMX_START="-Dcom.sun.management.jmxremote.port=2011 "
    ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.password.file=${ACTIVEMQ_CONF}/jmx.password"
    ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.access.file=${ACTIVEMQ_CONF}/jmx.access"
    ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.ssl=false"
    ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote -Djava.rmi.server.hostname=192.168.1.144"

对jmx.access、jmx.password文件进行权限更新，执行如下命令

chmod 400 conf/jmx.*
