ubuntu – SSH连接到Amazon EC2在Linux

前端之家收集整理的这篇文章主要介绍了ubuntu – SSH连接到Amazon EC2在Linux前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我正在尝试从ssh使用以下命令ssh来惊吓ec2实例
ssh -vi sec.ppk ubuntu@ec2-xx.compute-1.amazonaws.com

但连接失败

这是上述命令生成的调试输出

为什么要求密码为sec.ppk

有什么问题?谁能帮忙?

忘了提到,我使用FileZilla成功地建立了与上述凭据相同的连接

尝试
ssh -i /directory/keyname.pem ubuntu@ec2-xx.compute-1.amazonaws.com

.pem是您在设置实例时创建的密钥对文件
