打开套接字时出现 DataEndpointConnectionWorker 错误（连接被拒绝）-WSO2 APIM 密钥管理器

Question

我已经在分布式环境中设置了wso2 apim 2.1.0。我运行 WSO2 服务器（TrafficManager、KeyManager、Gateway、Publisher 和 Store）在同一台机器上。当我尝试从密钥管理器配置文件启动 KeyManager APIM 实例时，出现如下连接被拒绝错误。

我已遵循文档 https://docs.wso2.com/display/AM210/Distributed+Deployment+of+API+Manager#DistributedDeploymentofAPIManager-Step3.1-ConfiguretheKeyManager。据此，我只更改了 <APIGateway> 元素下 <ServerURL> 的 ip 和端口。除此之外，KeyManager 中的 apimanager.xml 没有任何变化。我不确定密钥管理器中端口 9711 的用途是什么？

Answer 1

问题是因为 KeyManager 的节流配置中的 datapublisher 连接。我发现的唯一解决方案是手动将 ReceiverURL 和 AuthURL 端口指定为 9611 和 9711。
