我正在尝试连接到AWS实例。我知道我肯定已经在桌面上下载了密钥对，但由于某些原因它无法识别它？我已使用chmod 400更改了权限，但仍会发生以下情况：
martycep:~ martincepeda1$ ssh -v -i “privatekey.pem” ec2-user@ec2-xx-xx-xx-xx.us-east-2.compute.amazonaws.com

martycep:~ martincepeda1$
任何建议/想法将不胜感激。谢谢。
答案 0 :(得分：0)
你能检查一下：
您使用的是正确的密钥位置。
密钥具有正确的权限。
您使用的是正确的密钥吗？
答案 1 :(得分：0)
警告：无法访问身份文件privatekey.pem：没有此类文件或 目录
此输出表明您没有任何名为“privatekey.pem”的文件
也许你改变了关键权限，如：
chmod 0400 **~/.ssh/privatekey.pem**
该文件应如下所示：
-r--------+ 1 user group 1671 Jun 5 11:37 privatekey.pem
在那种情况下你应该这样做：
ssh -i **~/.ssh/privatekey.pem** ec2-user@ec2-xx-xx-xx-xx.us-east-2.compute.amazonaws.com
检查你的钥匙在哪里！
解决之后，不要忘记你必须在主机中添加公钥：ec2-user@ec2-xx-xx-xx-xx.us-east-2.compute.amazonaws.com
cat 'your_public_key' >> ~/.ssh/authorized_keys
否则您的私钥将与服务器中的公钥不匹配。
