Question

我想通过hexo在远程服务器上建立一个博客，通过ssh作为root来连接它非常有效，并且我在〜/ .ssh / authorized_keys中添加了一个具有公共密钥的git用户。

-rw------- 1 git git 417 3月  26 23:17 authorized_keys
drwx------  2 git  git  4096 3月  26 23:17 .ssh

但是当我尝试以git用户身份通过ssh连接服务器时，它失败了。调试信息如下。谁能帮我找出哪一部分不对？

Answer 1

首先重命名authorized_keys中的文件然后为ssh文件夹和authorized_keys文件设置权限。

chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

SSH授权失败
