无法与gitlab建立ssh连接

问题描述：

我在gitlab上有一个项目，我试图推送一个提交。我首先用https url复制了项目，但之后将其改为ssh，然后运行cat ~/.ssh/id_rsa.pub，它给了我ssh密钥：我有拷贝将密钥粘贴到我的gitlab配置文件中的ssh密钥，但尝试推送提交我收到一条消息：无法与gitlab建立ssh连接

主机'gitlab'的真实性无法建立。 RSA密钥指纹是SHA256：cZiqgz2tMzLXftNIIXmQ9v + 6M38xM1LzxROnDM1OJ0Q。您确定要继续连接（是/否）吗？是警告：将'07 .no，'myIpAddress'（RSA）永久添加到已知主机列表中。权限被拒绝（公钥）。

在运行ssh -Tv [email protected]：

我该如何解决呢？

好的，所以它都会警告你正在连接的新主机，正如@Rohit Poudel正确回答的一样，但是在你的编辑中还会显示“Permission denied（publickey）”，暗示GitLab无法识别该密钥。您确定回购站位于您的用户帐户下，您大概还添加了您的SSH密钥？ – roryrjb

也只是为了确认，如果你运行'git remote -v'，它是否显示：'origin \t [email protected]：your_user_account/your_repo'而不是任何对'https'的引用？ – roryrjb

它显示git @ gitlab – Leff

答

它告诉你，你从来没有连接到这台服务器。如果你期待这一点，这是非常正常的。如果您偏执，请使用备用渠道验证密钥的校验和/指纹。（但是请注意，有人可以重定向您的ssh连接，也可以重定向Web浏览器会话。）

如果您在从此安装ssh之前已连接到此服务器，则服务器已用新密钥重新配置或者某人在欺骗服务器的身份。由于中间人攻击的严重性，它警告你可能性。

无论哪种方式，你都有一个安全的加密频道给某人。没有人没有与指纹相对应的私钥可以解码您发送的内容。

您用来验证自己身份的密钥是无关的......您不希望将身份验证信息发送给可能会窃取该密码的欺诈服务器，因此您不应该期待任何更改，具体取决于您是否要使用密码或私钥进行登录。你在这个过程中还没有那么远。

是的，我以前没有尝试过连接，这是我第一次，但是，因为这个，我无法推送任何东西，我该如何解决这个问题？ – Leff
