ssh - Amazon LightSail 上的权限被拒绝

Question

登录适用于 LightsailDefaultPrivateKey-eu-west-1.pem，但不适用于我自己的 key 对。

我尝试使用 'ssh-keygen -t rsa -b 4096 -C "my@email.com"-f ~/.ssh/lsail-mikemittererat-eu-west-1.pem' 生成 key

我还尝试在 AWS/S2 上生成一个 key ，下载它，用私钥生成一个公钥并将其上传到 LightSail - 相同的结果。它不起作用。

错误信息:
ssh -i ~/.ssh/ssh_my-website ubuntu@
权限被拒绝(公钥)。

如果我使用 -v 选项，这就是我得到的结果:

ssh -v -i ~/.ssh/lsail-mikemittererat-eu-west-1.pem ubuntu@<public ip>

.pem 权限设置为 600，.ssh 设置为 700

Answer 1

我能够让这个工作如下:

如上所述生成 SSH key 对 (ssh-keygen -t rsa -b 4096 -C "my@email.com"-f ~/certs/test.pem)

更改了私钥文件的权限 (chmod 600 test.pem)

使用 Lightsail 集成控制台 ssh 进入实例并将公钥添加到 ~/.ssh/authorized_keys 文件

我能够使用 ssh -i ~/certs/lightsail.pem ubuntu@

访问该实例

让我知道这是否有效，或者我是否遗漏了什么。
