EC2 ssh权限被拒绝publickey，gssapi-keyex，gssapi-with-mic

当我想要ssh到我的ec2主机时，我得到了这个权限被拒绝的问题。 我尝试了现有的解决schemechmod 600 "My.pem"但仍然没有工作。 这是我的debugging信息：

什么权限jenkins必须执行shell命令而不是不安全？

通过连接用户centos而不是ec2-user 。

将用户添加到/etc/sshd_special_user

我使用命令在我的centos机器上解决了这个问题：

ssh -i <Your.pem> ec2-user@<YourserverIP>

这是关于我的情况下ec2-user userName 。
