我正在跟进这教程，这就是我正在尝试的
ssh-copy-id -i ~/.ssh/id_rsa.pub remote_host
它说Permission denied (publickey,password).
我也尝试过ssh -v remote_host并验证过

答案1
您应该提供私钥ssh-copy-id或者根本不提供密钥，如命令概要中所述（来自手册页）：
ssh-copy-id [...] [-i [identity_file]] [-p port] [-o ssh_option] [user@]hostname
或者根本没有密钥（在这种情况下，它将复制标准位置中的所有密钥）。使用以下命令应该可以完成这项工作：
ssh-copy-id -i ~/.ssh/id_rsa remote_host
如果没有帮助，请运行
ssh-copy-id -i ~/.ssh/id_rsa -o LogLevel=DEBUG3 remote_host
并使用输出更新问题以进行进一步调查。
