停止时ActiveMQ异常

问题描述 投票：9回答：1

配置：Redhat 5.3，Sun Java 1.6.31，ActiveMQ 5.4.2

我每次停止activemq都会收到异常（$> service activemq stop）

这个过程仍然会死，但不会优雅。有什么建议？

我找到了修复，但我不确定它是否解决了根本问题。一旦ActiveMQ启动，我使用以下命令检查端口1099是否实际打开：

$> netstat -lptun | grep 1099

此命令不打印任何显示端口未打开（ActiveMQ已启动）。这意味着即使ActiveMQ已经启动，它也不会监听任何JMX连接（这是脚本试图阻止它的方式）。经过一番环顾，我发现这个link引导我进入{ACTIVEMQ_HOME} /conf/activemq.xml文件。在此文件中有以下部分：

 <!-- 
     The managementContext is used to configure how ActiveMQ is exposed in 
     JMX. By default, ActiveMQ uses the MBean server that is started by 
     the JVM. For more information, see: 

         http://activemq.apache.org/jmx.html 
 -->
 <managementContext>
   <managementContext createConnector="false"/>
 </managementContext>

设置createConnector =“true”解决了我的问题（这将在ActiveMQ启动时启动JVM中的MBean服务器）。关闭输出现在看起来像这样（如预期的那样）：

...
ACTIVEMQ_HOME: /opt/apache/apache-activemq-5.4.2
ACTIVEMQ_BASE: /opt/apache/apache-activemq-5.4.2
Connecting to JMX URL: service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi
Stopping broker: localhost
.. FINISHED

此外，更改此标志后，我可以验证启动ActiveMQ后默认的JMX端口（1099）是否已打开

$> netstat -lptun | grep 1099
tcp        0      0 :::1099                     :::*                        LISTEN      30033/java
