amazon-web-services - 尝试通过SSH进入Amazon Ec2实例-权限错误(Trying to SSH into an Amazon Ec2 instance - permission error)

Question

This is probably a stupidly simple question to some :)

(对某些人来说，这可能是一个愚蠢的简单问题：）)

I've created a new linux instance on Amazon EC2, and as part of that downloaded the .pem file to allow me to SSH in.

(我在Amazon EC2上创建了一个新的linux实例，并且作为其中一部分下载了.pem文件，以允许我进行SSH输入。)

When I tried to ssh with:

(当我尝试使用ssh时：)

ssh -i myfile.pem <public dns>

I got:

(我有：)

It is recommended that your private key files are NOT accessible by others.

Following this post I tried to chmod +600 the pem file, but now when I ssh I just get:

(在这篇文章之后，我尝试将+600 pem文件修改为chmod，但是现在当我ssh时，我得到的是：)

Permission denied (publickey).

What school-boy error am I making here?

(我在这里犯了什么男生错误？)

The .pem file is in my home folder (in osx).

(.pem文件在我的主文件夹中（在osx中??）。)

It's permissions look like this:

Answer 1

The problem is having wrong mod on the file.

(问题是文件上的mod错误。)

Easily solved by executing -

(执行即可轻松解决-)

chmod 400 mykey.pem

Taken from Amazon's instructions -

(取自亚马逊的指示-)

Your key file must not be publicly viewable for SSH to work.

(您的密钥文件必须是公开可见的，SSH才能正常工作。)

Use this command if needed: chmod 400 mykey.pem

(如果需要，请使用以下命令：chmod 400 mykey.pem)
