activemq版本为: 5.16.2

jdk版本为： jdk.1.8.0_201

再执行./activemq dstat 时，报如上错误，无法访问jmx的1099端口

activemq:INFO: Broker not available at: service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi

通过netstat -tnlp 发现没有1099端口，jmx没有启动，现在开启jmx。

1、修改配置文件 bin/env，开放如下注释

# ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.port=11099 "
# ACTIVEMQ_SUNJMX_START="$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"

改为:

#ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.port=11099 "
#ACTIVEMQ_SUNJMX_START="$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"

ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Djava.rmi.server.hostname=本机IP"

2、修改 conf/activemq.xml文件，两个地方

broker标签中添加 userJmx="true"

<broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}" schedulePeriodForDestinationPurge="300000" splitSystemUsageForProducersConsumers="true" producerSystemUsagePortion="50" consumerSystemUsagePortion="50" userJmx="true">

managementContext改为true

<managementContext>
<managementContext createConnector="true"/>
</managementContext>

3、修改jmx配置文件的读写权限

chmod 600 conf/jmx.access

chmod 600 conf/jmx.passwordd

4、按上述修改后，重启activemq

再次执行./bin/activemq dstat 可以显示出队列信息。

Tasks:
    browse                   - Display selected messages in a specified destination.
    bstat                    - Performs a predefined query that displays useful statistics regarding the specified broker
    consumer                 - Receives messages from the broker
    create                   - Creates a runnable broker instance in the specified path.
    decrypt                  - Decrypts given text
    dstat                    - Performs a predefined query that displays useful tabular statistics regarding the specified destination type
    encrypt                  - Encrypts given text
    export                   - Exports a stopped brokers data files to an archive file
    list                     - Lists all available brokers in the specified JMX context
    producer                 - Sends messages to the broker
    purge                    - Delete selected destination's messages that matches the message selector
    query                    - Display selected broker component's attributes and statistics.
    start                    - Creates and starts a broker using a configuration file, or a broker URI.
    stop                     - Stops a running broker specified by the broker name.

###删除队列中的所有消息，队列名称是test.undo.todo
./activemq purge test.undo.todo
