Artemis经纪人未宣布自己作为RHEL机器上的备份

如何解决Artemis经纪人未宣布自己作为RHEL机器上的备份

我有5个安装了ActiveMQ Artemis代理的Red Hat Enterprise Linux（RHEL）7.7系统。我已经配置了1个主机，其余配置为从机。主代理的broker.xml片段如下：

<connectors>
   <connector name="mainBrokerConnector">tcp://10.1.144.200:61616</connector>
</connectors>

<discovery-groups>
   <discovery-group name="my-discovery-group">
      <local-bind-address>10.1.144.200</local-bind-address>
      <group-address>231.7.7.7</group-address>
      <group-port>9876</group-port>
      <refresh-timeout>10000</refresh-timeout>
   </discovery-group>
</discovery-groups>
 
<cluster-connections>
   <cluster-connection name="my-cluster">
      <connector-ref>mainBrokerConnector</connector-ref>
      <retry-interval>500</retry-interval>
      <use-duplicate-detection>true</use-duplicate-detection>
       <message-load-balancing>STRICT</message-load-balancing>
      <max-hops>1</max-hops>
      <discovery-group-ref discovery-group-name="my-discovery-group"/>
   </cluster-connection>
</cluster-connections>

<broadcast-groups>
   <broadcast-group name="my-broadcast-group">
      <local-bind-address>10.1.144.200</local-bind-address>
      <local-bind-port>5432</local-bind-port>
      <group-address>231.7.7.7</group-address>
      <group-port>9876</group-port>
      <broadcast-period>2000</broadcast-period>
      <connector-ref>mainBrokerConnector</connector-ref>
   </broadcast-group>
</broadcast-groups>

<ha-policy>
   <replication>
      <master>
        <check-for-live-server>true</check-for-live-server>
      </master>
   </replication>
</ha-policy>

启动的四个备份代理中的三个（./artemis run）宣布自己为备份。在备份代理的日志中，我看到这样的内容（因此，我知道它们是同步的）：

2020-10-07 14:19:43,480 INFO  [org.apache.activemq.artemis.core.server] AMQ221024: Backup server ActiveMQServerImpl::serverUUID=e2fbfd28-04ec-11eb-b49a-005056aded6a is synchronized with live-server.
2020-10-07 14:19:43,768 INFO  [org.apache.activemq.artemis.core.server] AMQ221031: backup announced

但是，第四个代理会启动，但不会记录有关同步的任何内容。第四位经纪人的broker.xml代码段如下

<connectors>
   <connector name="brokerTwoConnector">tcp://10.1.144.202:61616</connector>
</connectors>

<discovery-groups>
   <discovery-group name="my-discovery-group">
      <local-bind-address>10.1.144.202</local-bind-address>
      <group-address>231.7.7.7</group-address>
      <group-port>9876</group-port>
      <refresh-timeout>10000</refresh-timeout>
   </discovery-group>
</discovery-groups>

<cluster-connections>
   <cluster-connection name="my-cluster">
      <connector-ref>brokerTwoConnector</connector-ref>
      <retry-interval>500</retry-interval>
      <use-duplicate-detection>true</use-duplicate-detection>
      <message-load-balancing>STRICT</message-load-balancing>
      <max-hops>1</max-hops>
      <discovery-group-ref discovery-group-name="my-discovery-group"/>
   </cluster-connection>
</cluster-connections>

<broadcast-groups>
   <broadcast-group name="my-broadcast-group">
      <local-bind-address>10.1.144.202</local-bind-address>
      <local-bind-port>5432</local-bind-port>
      <group-address>231.7.7.7</group-address>
      <group-port>9876</group-port>
      <broadcast-period>2000</broadcast-period>
      <connector-ref>brokerTwoConnector</connector-ref>
   </broadcast-group>
</broadcast-groups>

<ha-policy>
   <replication>
      <slave>
        <allow-failback>true</allow-failback>
      </slave>
   </replication>
</ha-policy>

其余的从代理具有相同的配置，但主机IP地址和连接器名称不同。那么，此代理未与主代理同步的配置不正确是什么？

当我启动罪魁祸首代理时，会出现以下日志，表明它是集群的一部分：
