AWS SSH 和 RDS 权限被拒绝 - public 密钥

Question

我正在尝试 SSH 并连接到我的 RDS 实例。两者都不起作用，给出相同的错误：

Permission denied (publickey).

我已经在 ~/.ssh/config 中设置了我的凭据：

Host clg-api-staging
     HostName ec2-11-111-11-11.compute-1.amazonaws.com   
     User ec2-user
     IdentityFile ~/.ssh/clg-api-staging.pem

我试过：

正在更改我对 pem 文件的权限：chmod 600 ~/.ssh/clg-api-staging.pem
正在将我对 ~/.ssh/ 的权限更改为 700
在端口 22 和端口 3306 上为 TCP 设置入站规则:

这是我尝试通过配置文件登录时的消息：

Answer 1

如果您尝试使用 SSH 连接到 RDS，那将永远行不通。 RDS 是一种数据库服务，只允许 SQL 连接，不允许直接 SSH 或其他管理员类型的访问。

Answer 2

您不能直接通过SSH 访问AWS RDS 实例。您可以通过 MySQL 客户端访问它。

安装apt-get install MySQL-server -y
运行 MySQL -h clg-api-staging -P password -p
