你好我在尝试ssh到我新创建的ec2实例时，在ec2免费套餐上获得了权限被拒绝，我搜索论坛并尝试提供的解决方案无济于事。我会非常感谢任何帮助。这就是我做的事情
首先使用以下
编辑〜/ .bashrcexport EC2_PRIVATE_KEY=$HOME/ec2/pk-4JGFV4LMAHPSI2RLN46Z2U5DSQ7F3IUO.pem
export EC2_CERT=$HOME/ec2/cert-4JGFV4LMAHPSI2RLN46Z2U5DSQ7F3IUO.pem
export JAVA_HOME=/usr/lib/jvm/java-6-openjdk/
然后
source ~/.bashrc
ec2-add-keypair ec2-keypair > ~/ec2/smitchell.pem
然后我通过web gui创建了实例，然后尝试ssh in via ssh -v -i /home/smitchell/ec2/smitchell.pem root@ec2-50-17-66-200.compute-1.amazonaws.com
该命令产生以下内容

我设法通过web配置删除实例和我的密钥对并重新生成它们，一旦我这样做，我就能登录了。感谢大家的帮助
