使用密钥进行 ssh 登录无法连接，尽管使用了 ssh 密钥

我有 2 台服务器，我想通过 ssh 将其中一台连接到另一台。

我是服务器 A 中的用户 --> userA，我在 .ssh 文件夹中有此配置文件

Host git
        HostName git.OURSITE.com
        User userB
        IdentityFile ~/.ssh/git

当然，我已经在 /home/userA/.ssh 文件夹中创建了一个名为“git”的密钥

并且我在服务器 B 中有一个用户 --> 用户 B，我将服务器 A 中的 git.pub 添加到其 /home/userB/.ssh/authorized_keys

现在我尝试以用户 B 的身份将用户 A 连接到服务器 B

用这个 -->

 ssh git -v

这是我的输出

知道为什么它仍要求我输入密码吗？

答案1

检查 ~/.ssh 是否有 700 所有权，该目录中的文件是否有 600。

但您还应该检查 HOME 目录和父目录的所有权。它们不应由组或其他人写入。

最后一个要求取决于 sshd 配置，但这是默认的。
