Amazon web services Bitnami Wordpress AWS实例的权限被拒绝（公钥）

我有一个Bitnami Wordpress的AWS实例

正在尝试使用以下命令进行连接：

ssh -N -L 8888:127.0.0.1:80 -i wordpress.pem bitnami@52.91.239.245 -v 

我明白了

这是否意味着找不到公钥？无法读取吗？

我删除了该实例并重新开始。这次我创建了一个新的.pem，而不是重用现有的.pem。当我用新的.pem创建实例时，我加入了。我认为重用.pem可能是个问题。谢谢大家的帮助

转到nano/Users/OWNER/.ssh/known_hosts并删除行号18，然后再次尝试ssh，结果显示：警告：已将“52.91.239.245”（RSA）永久添加到已知主机列表中。然后以与上面相同的最后13行结束。您是否尝试了普通SSH？您所说的普通SSH是什么意思？例如SSH-i//wordpress.pembitnami@52.91.239.245

sudo chmod 700 ~/.ssh/
sudo chmod 600 ~/.ssh/*
sudo chown -R OWNER ~/.ssh/
