我一直尝试通过 SSH 验证从 OS X 登录到 Azure 中运行 Ubuntu 的虚拟机。但是当我尝试连接到虚拟机时，我收到权限被拒绝（公钥）错误。
为了创建密钥对证书，我通过终端按照以下步骤进行操作：
openssl req -x509 -nodes -days 365 \
-newkey rsa:2048 \
-keyout example1.key \
-out example1.pem
然后我设置权限：
chmod 600 example1.key
这两个文件都在我的用户文件夹中。
在创建虚拟机期间，我上传了文件 example1.pem。
创建虚拟机后，我尝试使用以下命令进行连接：
ssh -v -i myPrivateKey.key -p 22 [email protected]
这是我得到的输出：

我尝试使用 VIP 而不是 VM 名称，但输出结果相同。我在网上搜索了所有信息，但还是找不到问题的解决方案。

因为没有说明，所以我必须问一下。您在创建虚拟机时添加了公钥吗？有一个步骤是上传 example1.pem，然后在安装过程中将其存储在用户的 ~/.ssh/authorized_keys 文件中。
