我正在尝试将我的id_rsa.pub推送到服务器,以便我可以进入它。
我运行以下命令,
cat ~/.ssh/id_rsa.pub | ssh -v -p 12345 myname@123.45.67.8 'cat >> ~/.ssh/authorized_keys'
返回以下调试:

我无法弄清楚问题是什么..有人可以帮帮我吗?
基于密钥的身份验证仅在authorized_keys具有正确权限时才有效。
尝试做一个chmod 600~ / .ssh / authorized_keys
只有输入密码才能通过ssh访问服务器,您的命令才有效。它还需要在远程服务器上创建dir~ / .ssh,最后(正如Jan-Erik Revsbech指出的那样)本地和远程的权限〜/ .ssh需要禁止其他人读取它。
如果您改为使用ssh-copy-id remote-server
来复制密钥,那么远程系统上的目录和权限都将被正确设置。但是,它仍然需要您第一次输入密码。
确保也设置正确的所有者:)
我按照Ole的建议尝试了ssh-copy-id remote-server
并得到如下错误:
无法写入.ssh / authorized_keys。没有权限
目录~/.ssh
以及文件authorized_keys
已经存在于服务器上,并设置了正确的权限......但对于错误的用户!这是什么解决了它:
chown right-user:right-user .ssh
chown right-user:right-user .ssh/authorized_keys
我更改了文件的所有者和目录。然后ssh-copy-id
工作。
