git - SSH 授权失败
问题描述
我想在远程服务器上通过 hexo 建立一个博客,通过 ssh 作为 root 连接它效果很好,我在 ~/.ssh/authorized_keys 中添加了一个带有公钥的 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是错的?

解决方案
首先重命名文件,authorized_keys
然后设置对 ssh 文件夹和 authorized_keys 文件的权限。
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys
