Question

我正在尝试在Openshift中以主/从模式部署ActiveMQ Artemis群集，但是我不断收到此警告：

2019-01-09 07:50:40,192 WARN  [org.apache.activemq.artemis.core.server] AMQ222137: Unable to announce backup, retrying: ActiveMQConnectionTimedOutException[errorType=CONNECTION_TIMEDOUT message=AMQ119012: Timed out waiting to receive initial broadcast from cluster]

当我在同一台机器上使用此配置时，它可以正常工作。但是，当我对它进行Dockerize并在每个容器中部署一个代理时，它会失败。

这是代理1的配置：

启用DEBUG日志记录后，将显示以下内容：

Answer 1

这里有几个问题...

首先，您的连接器配置不正确。在经纪人1上，您正在使用此：

<connector name="netty-connector">tcp://0.0.0.0:61616</connector>

在经纪人2上，您正在使用此：

<connector name="netty-connector">tcp://0.0.0.0:61617</connector>

此连接器信息由集群的每个成员发送，以通知其他集群成员如何将其连接回发送该信息的节点。例如，在您的情况下，代理1告诉代理2它可以使用tcp://0.0.0.0:61616连接回代理1。当然，这不是正确的，因为元地址0.0.0.0实际上并不指向代理1。当代理2尝试使用此URL时，您将看到它失败。

在同一主机上运行两个代理时，此方法起作用的原因是，0.0.0.0将解决与localhost相同的问题。

您需要在连接器配置中使用有效的IP地址或主机名，以便群集可以正确地形成。

第二，您提供的DEBUG日志指示在两个Docker实例之间多播流量不起作用。我建议您尝试使用 static 群集从环境中消除多播问题。在经纪人1上，您可以使用类似的内容：

<connectors>
     <connector name="netty-connector">tcp://broker1:61616</connector>
     <connector name="broker2-connector">tcp://broker2:61617</connector>
</connectors>

...

<cluster-connections>
   <cluster-connection name="my-cluster">
      <connector-ref>netty-connector</connector-ref>
      <static-connectors>
         <connector-ref>broker2-connector</connector-ref>
      </static-connectors>
   </cluster-connection>
</cluster-connections>

在代理2上，您可以使用类似以下内容的东西：

<connectors>
     <connector name="netty-connector">tcp://broker2:61617</connector>
     <connector name="broker1-connector">tcp://broker1:61616</connector>
</connectors>

...

<cluster-connections>
   <cluster-connection name="my-cluster">
      <connector-ref>netty-connector</connector-ref>
      <static-connectors>
         <connector-ref>broker1-connector</connector-ref>
      </static-connectors>
   </cluster-connection>
</cluster-connections>

当然，您需要为连接器中的实际节点使用IP地址或主机名。
