我正在CentOS 6.7上安装ActiveMQ 5.13.1。我觉得这个教程：

我几乎是同路人，现在我可以进入了 从远程客户端，它显示“欢迎使用Apache ActiveMQ！”页面，但一旦打开，就会出现错误：

HTTP ERROR 500

Problem accessing /admin/. Reason:

Server Error

实际上有些步骤我做不到：

sudo /opt/activemq/bin/activemq-admin list

它说没有activemq管理员

在我这样做之后：

sudo /opt/activemq/bin/activemq setup /etc/default/activemq

/未创建etc/default/activemq。所以我不能做：

sudo chown root /etc/default/activemq 

及

我还提供了另一个答案（）将配置文件从

<import resource="jetty.xml"/>

到

<import resource="jetty.xml"/>

<import resource="${activemq.base}/conf/jetty.xml"/>
