linux - ssh key 不适用于 linux 主机

Question

我正在尝试在我的 Linux 托管服务上将 ssh key 与 git 结合使用。

我确实检查了大量指南，但似乎没有一个适合我，所以也许需要一些人工帮助。

这是我所做的:

• 我的 mac 上已经有了公钥和私钥的 key 对

• 我已将此公钥添加到 bitbucket

• 如果(从 mac 上)我输入 ssh -T git@bitbucket.org，它要求输入密码，它说我已经登录，这意味着它正在工作并且 key 是正确的

现在，在 linux 服务器主机上:

• 我转到 ~/.ssh/并在此处我有以下文件:

authorized_keys -> /etc/support.pub (i cannot access this because of host limitations)

authorized_keys2 -> with my public id_rsa (format: id_rsa #######)

id_rsa -> my public key (format: id_rsa #######)

我还创建了一个名为 config 的文件，如下所示:

主机 bitbucket.com-{username} 主机名 bitbucket.com 用户 git 身份文件 ~/.ssh/id_rsa.pub

但是当我输入:ssh -T git@bitbucket.org

我收到此错误:Permission denied (publickey).

详细日志显示:

我错过了什么？示例、论坛或谷歌搜索都没有帮助我解决这个问题，托管支持也没有。

感谢您的帮助。

ls -la ~/.ssh 输出:

drwx------  2 user user 4096 Dec 12 17:22 .
drwx--x--x 16 user user 4096 Dec 12 16:52 ..

Answer 1

您可以尝试这些解决方案:

1- ssh-agent :

要么使用 ssh-agent(应该包含在 openssh 中)来管理身份:

> eval "$(ssh-agent -s)"
> ssh-add /path/to/private_key

2- ~/.ssh/config 文件:

在客户端的 ~/.ssh/config 设置 ssh 配置。这是 github 配置的示例:

Host github github.com
Hostname github.com
User git
IdentityFile ~/.ssh/github 

3- [编辑]:通过 CLI 直接将路径传递给身份文件:

ssh -T git@bitbucket.org -i /path/to/key

当然，公钥必须添加到服务器端的authorized_keys文件中。
