当我正在抨击时，我对这个对讲的含义感到困惑。
我觉得如果我能理解它，我可以解决我遇到的问题，也就是说，我得到了
debug1: No more authentication methods to try. Permission denied (publickey).
这是对讲：

第一个粗体显示ssh正在尝试提供私钥key_A。但key_A是一个不同的密钥，与完全不同的服务器相关。它与我试图访问的AWS实例无关。
第二个粗体线是找到正确的密钥key_B。但等等，这是私钥？这是我在AWS控制台上生成并在登录时尝试使用的密钥。
为什么ssh首先尝试访问随机公钥，然后开始寻找私钥？它找不到正确的公钥。
我的ssh是：
ssh -i /me/somedir/key_B.pem ec2-user@XXXXX.us-east-2.compute.amazonaws.com
为什么ssh不会出现在正确的位置？
提前致谢。
答案 0 :(得分：0)
为什么ssh首先尝试访问随机公钥，
因为它很可能配置为。您在~/.ssh/config或/etc/ssh/ssh_config中拥有什么？
然后开始寻找私钥？它找不到正确的公钥。
我的ssh是：
ssh -i /me/somedir/key_B.pem ec2-user@XXXXX.us-east-2.compute.amazonaws.com为什么ssh不会出现在正确的位置？
debug1: identity file /me/key_B.pem type -1
因为它不懂钥匙。它要么格式错误，要么以某种方式破坏。它看起来怎么样？
