问题描述
我能够连接到VPC中的 Redis实例来自 EC2实例。但是我想知道是否有一种方法可以连接到Amazon EC2实例外部的ElastiCache Redis节点，例如从我的 local 开发设置或其他供应商提供的VPS实例。
I'm able to connect to an ElastiCache Redis instance in a VPC from EC2 instances. But I would like to know if there is a way to connect to an ElastiCache Redis node outside of Amazon EC2 instances, such as from my local dev setup or VPS instances provided by other vendors.
当前从我的本地设置尝试时：
Currently when trying from my local set up:
redis-cli -h my-node-endpoint -p 6379
一段时间后我只会超时。
I only get a timeout after some time.
推荐答案
不，您不能不采取诸如隧道之类的技巧，虽然可以进行测试，但会扼杀使用该工具的任何真正好处
No, you can't without resorting to 'tricks' such as a tunnel, which maybe OK for testing but will kill any real benefit of using a super-fast cache with the added latency/overhead.
从此处：
编辑2018：上面的答案在撰写时是准确的，但是现在可以通过一些配置使用此页面下大约1/2的方向从外部访问redis缓存：
EDIT 2018: This answer above was accurate when written, however it is now possible with some configuation to access redis cache from outside using the directions approximately 1/2 way down this page: https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/accessing-elasticache.html#access-from-outside-aws
