添加ssh公钥到服务器

我试图推我的id_rsa.pub到服务器，所以我可以ssh进入它。添加ssh公钥到服务器

我已经运行下面的命令，

cat ~/.ssh/id_rsa.pub | ssh -v -p 12345 [email protected] 'cat >> ~/.ssh/authorized_keys'

返回以下调试：

我想不通的问题是什么.. 任何人可以帮我出来吗？

基于密钥的身份验证只有在authorized_keys拥有权限时才有效。

尝试做在chmod 600的〜/ .ssh/authorized_keys中

你的意思是在我的电脑上？显然我没有一个名为authorized_keys的文件。这是我需要生成的东西吗？ – ytrewq 2014-10-29 07:20:00

对不起，那还不清楚。它不在本地计算机上，而是在远程计算机上。您最初运行的命令（来自您的问题）在远程计算机上生成了该文件。试着做一个ssh -v -p 12345 [email protected]'chmod 600〜/ .ssh/authorized_keys – 2014-10-29 08:27:35

thanx，但是这也导致了同样的错误。 – ytrewq 2014-10-29 14:53:18

你的命令，如果你可以通过输入密码ssh到服务器将只工作。它还需要在远程服务器上创建dir〜/ .ssh，最后（如Jan-Erik Revsbech指出的）本地和远程〜/ .ssh的权限需要禁止其他人读取它。

如果您使用ssh-copy-id remote-server来复制您的密钥，那么远程系统上的dir和权限都将被正确设置。不过，它仍然会要求您第一次输入密码。

显然ssh-copy-id不起作用Mac终端..是否有其他选择？ – ytrewq 2014-10-29 07:33:08

你正在做的是另一种方式，但在遥控器上你需要使用密码和'mkdir .ssh登录; chmod 700 .ssh; touch .ssh/authorized_keys; chmod 600 .ssh/authorized_keys'，然后再运行命令。 – 2014-10-29 08:49:30

*** SOOOOOOOO ***比确保所有权限设置正确要容易得多！ – n0nag0n 2017-10-09 17:20:35
