将DAX与DynamoDB一起使用时,无法配置集群端点错误

Question

我根据AWS的教程创建了一个集群,它应该工作得很好但是当我尝试连接到它时,我收到以下错误

我们需要了解有关如何设置DAX群集和客户端实例以便能够提供帮助的更多信息.一些一般的想法尝试:

1. 您是否能够从EC2客户端实例连接到DAX群集？试试跑步: nc -z mydaxcluster.ximfba.clustercfg.dax.use1.cache.amazonaws.com 8111
2. 您是否使用VPC的默认安全组来创建DAX群集？您需要将TCP端口8111上的入站流量授权给用于从客户端实例的安全组创建DAX群集的安全组.请按照为VPC配置安全组规则的步骤进行操作
