AWS ssh访问'Permission denied(publickey)'问题

如何通过ssh连接到AWS实例？

我有:

在AWS注册;

在AWS网站上创建公钥和证书并将其保存到磁盘;

去了我的控制台并创建了环境变量:

$ export JAVA_HOME=/usr/lib/jvm/java-6-openjdk/
$ export EC2_CERT=/home/default/aws/cert-EBAINCRNWHDSCWWIHSOKON2YWGJZ5LSQ.pem
$ export EC2_PRIVATE_KEY=/home/default/aws/pk-EBAINCRNWHDSCWWIHSOKON2YWGJZ5LSQ.pem

告诉AWS API使用此密钥对并将密钥对保存到文件:

$ ec2-add-keypair ec2-keypair > ec2-keypair.pem

使用此密钥对启动AWS Ubuntu 9实例:

$ ec2-run-instances ami-ed46a784 -k ec2-keypair

尝试与实例建立ssh连接:

$ ssh -v -i ec2-keypair.pem ubuntu@ec2-174-129-185-190.compute-1.amazonaws.com

可能是什么问题以及如何使其发挥作用？

对于Ubuntu实例:

chmod 600 ec2-keypair.pem
ssh -v -i ec2-keypair.pem ubuntu@ec2-174-129-185-190.compute-1.amazonaws.com

对于其他情况,您可能必须使用ec2-user而不是ubuntu.

我使用的大多数EC2 Linux映像都默认创建了root用户.

对于Ubuntu实例:

现在是:

ssh -v -i ec2-keypair.pem ec2-user@[yourdnsaddress]

Canonical的版本默认使用用户'ubuntu'来登陆这里的任何人使用ubuntu图像来解决同样的问题.

如果您使用的是Bitnami图像,请以"bitnami"身份登录.

看似显而易见,但我忽视了一些事情.

ssh -v -i [yourkeypairfile] ec2-user@[yourdnsaddress]

ssh -v -i GSG_Keypair.pem ec2-user@ec2-184-72-204-112.compute-1.amazonaws.com
