Question

我在用HA配置群集中的两个Artemis服务器时遇到问题。

目标：

启动群集中的两台服务器，一台处于活动状态，第二台为备份。在运行时，只有实时服务器应该收到消息。
两台服务器应共享配置和消息（其中一台发生故障时）

问题：

当我使用 ctrl - c 停止实时服务器时，从服务器报告Connection failure to localhost/127.0.0.1:61616 has been detected: AMQ219015: The connection was disconnected because of server shutdown [code=DISCONNECTED]是正确的，但备用服务器未更改其状态，并且没有在端口61617上监听。那我在配置中做错了什么？

实时服务器配置：

如果您正常停止代理（例如，使用 ctrl - c ），则默认情况下不会发生故障转移。要通过正常关机触发故障转移，您需要像这样配置 master 代理：

<ha-policy>
   <shared-store>
      <master>
         <failover-on-shutdown>true</failover-on-shutdown>
      </master>  
   </shared-store>
</ha-policy>

和从属一样：

<ha-policy>
   <shared-store>
      <slave>
         <failover-on-shutdown>true</failover-on-shutdown>
      </slave>  
   </shared-store>
</ha-policy>

否则，您可以杀死代理（例如，使用kill -9 <pid>）来触发故障转移。

故障转移在静态集群HA中不起作用
