The "quick and dirty" approach is to give your EC2 a public IP, then expose your MySql by adding a rule on a security group to allow ingress from the IP of the caller (or any IP) on port 3306. I am not sure but I think that you also have to adjust MySql configuration to allow connection from other IP than localhost. “快速而肮脏”的方法是为您的 EC2 提供一个公共 IP，然后通过在安全组上添加一条规则以允许从 IP0 的端口 3 上的 IP 进入，从而公开您的 MySql。但我认为您还必须调整 MySql 配置以允许来自其他 IP 的连接而不是本地主机。
The cleanest way would be to build a set of API, with the programming language you are more confident and expose some GET method by means of REST services.最干净的方法是构建一组 API，使用您更有信心的编程语言并通过 REST 服务公开一些 GET 方法。
