AWS SSH和RDS权限被拒绝 - 公钥

Question

我尝试SSH并连接到我的RDS实例。两者都没有工作，给出了同样的错误：

  

许可被拒绝（公钥）。

我已在~/.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

我试过了：

• 更改pem文件的权限：chmod 600 ~/.ssh/clg-api-staging.pem

• 将我对~/.ssh/的权限更改为700

• 在端口22上设置TCP的入站规则，在端口3306上设置MYSQL：

当我尝试通过个人资料登录时，这是消息：

Answer 1

如果您尝试使用SSH连接到RDS，则永远不会起作用。 RDS是一种数据库服务，仅允许SQL连接，而不是直接SSH或其他管理员类型访问。

Answer 2

直接您无法通过SSH访问AWS RDS实例。 您可以通过MySQL客户端访问它。

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