我完全不懂编程,正在Coursera上学习初创企业课程:https://class.coursera.org/startup-001/lecture/87
我在尝试连接我在AWS上创建的EC2 Ubuntu实例时遇到了“Permission Denied (publickey)”错误。
- 设置AWS实例
- 将安全性设置为默认值,并添加端口22,然后启动
课程告诉我接下来输入:
chmod 400 trevor-learning.pem ssh -i trevor-learning.pem \ ec2-user@ec2-XX-XXX-XX-XX.us-west-2.compute.amazonaws.com
然后我就收到了这个错误:Permission denied (publickey)。
我查看了其他问题并尝试将ubuntu@切换为ec2-user和其他一些方法,但仍无法连接。
我还尝试了以下内容: trevor-larsons-macbook-pro:downloads trev$ chmod 600 trevor-learning.pem trevor-larsons-macbook-pro:downloads trev$ ssh -v -i trevor-learning ubuntu@ec2-XX-XXX-XX- XX.us-west-2.compute.amazonaws.com
它给了我:

我完全不知道该怎么做,请帮帮我!
另外,不确定这是否与此有关,当我下载实例证书(显示在Chrome浏览器左下角时),它会打开我的钥匙串访问并显示“发生错误。无法导入项目。无法检索此项目的内容。”
警告:身份文件trevor-learning不可访问:没有这个文件或目录。
