Gitlab 个人服务器：权限被拒绝（公钥）

Question

我已经安装了 Gitlab 服务器（15.1）并尝试为我的用户完成配置。

我可以将 ssh 连接到服务器以进行管理。我的用户。 我为此使用 rsa 密钥对。 我连接到 22002 端口，一切正常。

现在我想按照 Gitlab 指令创建一个项目，一对新的密钥并使用这个密钥对将我的存储库连接到 Gitlab。 I have created keys (ed25519), copy the public part into the Gitlab web server and just try the command ssh -T myuser@gitlab.mydomain.com

我得到以下结果：

权限被拒绝（公钥）

我已经搜索了几个小时，但没有找到我做错了什么。

如果我运行ssh -Tvvv myuser@gitlab.mydomain.com我得到以下结果：

谢谢你的帮助。

Answer 1

我确信这是我省略的一些简单的事情。 所以今天早上我只是继续在本地设置我的 git 项目，并使用我的用户和密码进行了第一次推送。 那运作良好。 然后，我编辑 my.ssh/config 文件，按照@VonC 的建议将我的用户名更改为“git”。 重新运行测试，它要求输入密钥的密码，一切正常。 我以为我可以在进行第一次推送或在本地设置原点之前设置 ssh，但似乎不行。

再次感谢您的宝贵意见。

Answer 2

将 SSH URL 与 GitLab 本地服务器一起使用应始终涉及技术帐户 Z76F11，而不是“33my3492”BD61E593
请参阅“ 验证您是否可以连接”

ssh -Tvvv git@gitlab.mydomain.com

GitLab 将通过注册到 GitLab 用户帐户 SSH 设置页面的公钥对您进行身份验证。
