如何使用 SSH 隧道从本地环境访问 Neptune 数据库? [英] How can I access the Neptune Database from my local environment using SSH tunnel?
问题描述
我有应用程序和网络负载平衡器.EC2 实例和 Neptune 在同一个 VPC 组中.我可以使用 ssh username@ 访问 EC2 实例，并且可以访问那里的 Gremlin 服务器并执行查询，但是如何从中建立隧道以便我可以在本地环境中使用它?如果您需要更多详细信息，请告诉我.
I have both application and network load balancer. EC2 instance and the Neptune are in the same VPC group. I am able to access the EC2 instance by using ssh username@ and can access the Gremlin server there and execute queries but how can I make a tunnel out of it so that I can use it from the local environment? Let me know if you need more detail.
推荐答案
您是否直接连接到 EC2，或者两者之间是否存在 NLB 或 ALB，并不是 100% 清楚的.如果您通过 SSH 从本地计算机直接连接到 EC2 以构建到 Neptune 的隧道，则可以使用诸如此类的命令.
It's not 100% clear if you are connecting directly to EC2 or whether there is a NLB or an ALB in between. If you are connecting from a local machine via SSH directly to EC2 to build a tunnel to Neptune, a command such as this will work.
ssh -i mycreds.pem ec2-user@ec2-xx-xx-xx-xx.compute-1.amazonaws.com -N -L 8182:my-neptune-cluster.us-east-1.neptune.amazonaws.com:818
为了解析 SSL 凭证，您可能需要在 hosts 文件中添加一行:
In order to get the SSL credentials to resolve you will likely need to add a line to your hosts file along the lines of:
127.0.0.1 localhost my-neptune-cluster.us-east-1.neptune.amazonaws.com
