java - 无法绑定(bind)到 Openshift 上的端口

Question

我在 openshift 上的应用程序中运行嵌入式 activemq 消息服务器。根据 this ，您只能绑定(bind) 15000 - 35530。我试过执行以下操作，但它抛出了一个严重的错误。可能是什么问题？

我正在使用 Spring 。这是我的 applicationContext.xml

中的一部分

<amq:broker brokerName="tentacle-broker" start="true">
    <amq:persistenceAdapter>
        <amq:amqPersistenceAdapter directory="/var/lib/openshift/username/jbossews-2.0/jbossews-2.0/activemq2" maxFileLength="32mb"/>
    </amq:persistenceAdapter>
    <amq:transportConnectors>
        <amq:transportConnector uri="tcp://127.10.180.129:15001"/>
    </amq:transportConnectors>
</amq:broker>

这是我遇到的错误

在 Openshift 中，您只能绑定(bind)到服务器为您分配的端口。这通常是环境变量 $OPENSHIFT_JBOSS_PORT 的值(它因卡式盒而异)并且该值因齿轮而异。绑定(bind)到任何其他端口将被报告为违反 SELinux 策略并被拒绝。
