我在Amazon EC2上创建了一个新的linux实例,并下载了.pem文件以允许我SSH登录。

当我试图ssh与:

ssh -i myfile.pem <public dns>

我有:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@         WARNING: UNPROTECTED PRIVATE KEY FILE!          @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
Permissions 0644 for 'amazonec2.pem' are too open.
It is recommended that your private key files are NOT accessible by others.
This private key will be ignored.
bad permissions: ignore key: amazonec2.pem
Permission denied (publickey).

在这篇文章之后,我尝试chmod +600 .pem文件,但现在当我ssh时,我只是得到

Permission denied (publickey).

我犯了什么小学生的错误? pem文件在我的主文件夹中(在macOS中)。它的权限是这样的:

-rw-------@   1 mattroberts  staff    1696 19 Nov 11:20 amazonec2.pem

嗯,看了你的帖子描述,我觉得你犯了两个错误:-

设置正确的私钥权限。 下面的命令将帮助您设置正确的文件权限。 Chmod 0600 mykey.pem 您试图登录的ec2用户错误。 查看您的调试日志,我认为您已经生成了一个Amazon linux实例。该实例类型的默认用户是ec2-user。如果实例是ubuntu,那么默认用户就是ubuntu。 SSH -i privatekey。pem default_ssh_user@server_ip

Note: For an Amazon Linux AMI, the default user name is ec2-user. For a Centos AMI, the default user name is centos. For a Debian AMI, the default user name is admin or root. For a Fedora AMI, the default user name is ec2-user or fedora. For a RHEL AMI, the default user name is ec2-user or root. For a SUSE AMI, the default user name is ec2-user or root. For an Ubuntu AMI, the default user name is ubuntu. Otherwise, if ec2-user and root don't work, check with the AMI provider.

如果没有权限别忘了sudo。 Sudo SSH -i myfile。pem < < ssh_user > > @ < >

解决这个问题的方法是将.pem文件移到apps目录中。fooapp是我的应用程序的名字。我把它直接放在那里。

使用PuTTY登录。它很好,但需要几个步骤。

Get your .pem that was generated when you first made the EC2 instance. Convert the .pem file .ppk using PuttyGen since PuTTY does not read .pem. Open PuTTY and enter your Host Name which is your instance username + Public DNS (Ex. ubuntu@ec2-xxx-xxx-xxx-xxx.region.compute.amazonaws.com). Not your AWS account username. Then navigate to Connection > SSH > Auth. Then add your .ppk file. Click on Browse where it says "Private key file for authentication". Click Open and you should be able to immediately establish connection.

我使用PuTTY 0.66在Windows。

默认权限不允许pem键。 你只需要更改权限:

Chmod 400 xyz.pem

如果是ubuntu实例,则使用:

SSH -i xyz。pem ubuntu@ec2-youraws.amazonaws.com
