java - 将 DAX 与 DynamoDB 结合使用时出现配置集群端点失败错误

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，出现以下错误

无法读取项目 无法调用集群端点:没有可用的端点

Answer 1

我们需要了解有关您如何设置 DAX 集群和客户端实例的更多信息才能提供帮助。一些可以尝试的一般想法:

1. 您能否从 EC2 客户端实例连接到 DAX 集群？尝试运行: 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 集群？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 集群的安全组。请按照 configuring security group rules for your VPC 的步骤操作
