Linux 无法SSH到EC2实例pem'；'；的权限0777；。ssh/intuit-tke-qe.pem'；太开放了'；

我无法ssh到我的EC2实例中，这似乎是我传递给ssh的ssh.pem文件的权限级别的问题，谷歌搜索这似乎是许多其他人都遇到过的问题，但他们的解决方案不适合我

这是我试过的，有人请帮忙

Atempt 1:

asemani$ ssh -i ~/.ssh/secure.pem root@54.210.0.1

我再也没有收到警告，但许可仍然被拒绝。然后，我还尝试在.pem文件上执行

chmod 400

，但也不起作用。我不会把它贴在这里，因为那可能是过分的

这里发生了什么？如何将ssh连接到ec2中？这应该很简单？？？

您需要通过AWS EC2管理控制台启动实例。启动后，复制公共DNS IPv4并将其粘贴到使用的linux分发名称后（例如。ubuntu@IPv4). 此外，请确保您正在存放您的私人访问密钥的目录中工作

为澄清起见，一旦启动EC2实例并位于保存私有访问密钥的目录中，请在命令行中键入以下内容：

ssh -i private_access_key.pem linux@IPv4

---

您是否能够使用

pem

键作为默认用户登录？对于Ubuntu实例，默认用户应该是

Ubuntu

；对于大多数其他情况，它应该是

ec2用户

。如果您能够以默认用户身份登录，则

root

不允许

ssh

登录。要更改此设置，请以默认用户身份登录并执行以下操作：

# Edit sshd_config and modify 'PermitRootLogin XX' to 'PermitRootLogin yes'
sudo vi /etc/ssh/sshd_config

# Reload sshd configuration
sudo service sshd reload

---

将权限更改为

chmod 400~/.ssh/secure.pem

，感谢您的解决方案奏效。我可以以root用户身份登录
