Question

我正在实施复制的leveldb activemq设置。我在同一个盒子上运行了3个activemq实例。我正在配置文件中更改他们的rmiPort，amqpport和openwire端口。

配置看起来像这样：

   <?xml version="1.0" encoding="UTF-8"?><beans xmlns=" http://www.springframework.org /schema/beans" xmlns:amq=" http://activemq.apache.org/schema/core" xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://activemq.apache.org/schema/core http://activemq.apache.org/schema/core/activemq-core.xsd">

我的实例文件如下所示：

 ACTIVEMQ_BASE=`cd "$ACTIVEMQ_BASE" && pwd`

 ## Add system properties for this instance here (if needed), e.g
 #export ACTIVEMQ_OPTS_MEMORY="-Xms256M -Xmx1G"
 #export ACTIVEMQ_OPTS="$ACTIVEMQ_OPTS_MEMORY
-Dorg.apache.activemq.UseDedicatedTaskRunner=true
-Djava.util.logging.config.file=logging.properties"

 export ACTIVEMQ_SUNJMX_CONTROL="-Dactivemq.jmx.url=service:jmx:rmi:///jndi/rmi://127.0.0.1:8100/jmxrmi"
 #
 ACTIVEMQ_SUNJMX_START="-Dcom.sun.management.jmxremote.port=8100 "
 ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.authenticate=false"   
 ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.ssl=false"


 export ACTIVEMQ_SUNJMX_START=$ACTIVEMQ_SUNJMX_START
 export ACTIVEMQ_HOME=/opt/gwx/apache-activemq-5.10-SNAPSHOT
 export ACTIVEMQ_BASE=$ACTIVEMQ_BASE

  export JAVA_HOME=/opt/gwx/apache-activemq-5.10-SNAPSHOT/jdk1.7.0_25

  ${ACTIVEMQ_HOME}/bin/activemq "$@"

以下是我得到的例外情况：

 Connecting to pid: 2410
 INFO: failed to resolve jmxUrl for pid:2410, using default JMX url Connecting to JMX URL: service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi

我检查了防火墙。它没有问题。

知道可能导致此问题的原因。

Activemq版本5.10快照

Java 1.7

OS linux 6.4

如果它仍然可以帮助某人：

当我进入bin / env时

 export ACTIVEMQ_SUNJMX_CONTROL="-Dactivemq.jmx.url=service:jmx:rmi:///jndi/rmi://127.0.0.1:8100/jmxrmi"
 #
 ACTIVEMQ_SUNJMX_START="-Dcom.sun.management.jmxremote.port=8100 "
 ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.authenticate=false"   
 ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.ssl=false"

，它没有工作，即使没有记录也没有进程。我不知道为什么，但这种方法有效（对于AMQ 5.13）：你将xml添加到：

<managementContext>
            <managementContext connectorPort="1099"/>
</managementContext>

和无，如env文件中的ACTIVEMQ_SUNJMX_START

Activemq Shutdown失败然后终止进程
