无法绑定到Openshift上的端口 [英] Unable to bind to a port on Openshift

问题描述

我在openshift的应用程序中运行嵌入式activemq消息服务器。根据这个，您只能绑定 15000 - 35530 。我已经尝试过以下操作，但它会引发严重的错误。可能是什么问题？

I am running an embedded activemq message server in my application on openshift. According to this, you can only bind on 15000 - 35530. I've tried doing the following, but it's throwing a serious error. What could be the issue?

我正在使用春天。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

推荐答案

在Openshift中，您只能绑定到服务器为您分配的端口。通常，这是环境变量$ OPENSHIFT_JBOSS_PORT的值（它在墨盒之间变化），并且齿轮之间的值不同。绑定到任何其他端口将被报告为SELinux策略违规并被拒绝。

In Openshift, you may only bind to the port that the server allocates for you. Typically that is the value of the environment variable $OPENSHIFT_JBOSS_PORT (it varies between cartridges) and the value differs between gears. Binding to any other port will be reported as an SELinux policy violation and denied.
