我正在尝试从 centos 7 机器 ssh 进入我的 ec2 实例。我已将 .pem 文件添加到 .ssh 文件夹。

我错过了什么吗？

[root@localhost .ssh]# cd /home/###/.ssh/
[root@localhost .ssh]# ls
##.pem

root@localhost .ssh]# ssh centos@10.100.140.52 -vvv


debug1: Trying private key: /root/.ssh/id_rsa
debug3: no such identity: /root/.ssh/id_rsa: No such file or directory

您是 root 用户 - 如果您在同一目录中有一个 pem 文件并不重要，它会在默认目录中查找（在您的情况下是 /root/.ssh）。如果要使用该 pem 文件，请使用“-i”命令行选项：

ssh -i something.pem centos@10.100.140.52 -vvv

我看到您使用的是 root shell，但您的问题表明密钥凭据存储在用户的主目录中。这是否作为该用户工作，即

[root@localhost .ssh]# su - ###
[###@localhost ~]$ ssh centos@10.100.140.52 -vvv

您也可以尝试覆盖 ssh 客户端查找 .ssh 文件的位置，尽管 ssh 对不匹配的文件权限很挑剔，即

[root@localhost ~]# ssh -i ~###/.ssh/something.pem centos@10.100.140.52 -vvv

您可以将连接“配置文件”存储在 ~/.ssh/config 中，即

Host ec2
  HostName 10.100.140.52
  IdentityFile ~/.ssh/identity_file
