无法“git pull"- 主机密钥验证失败 [英] Not able to "git pull" - Host key verification failed

问题描述

我对我们的生产服务器具有 root 访问权限，我想将 git 中的最新版本部署到服务器，但是当我在要更新的文件夹上git pull"时遇到以下错误.

我浏览了一下，但找不到明确的答案.

登台服务器在同一台机器上运行，但只是在不同的文件夹中，当我在该文件夹中 pull 时一切正常.

我在 Linux 方面不是很有经验，所以请帮助我明确回答如何修复 :-)

否则我可以访问我需要的任何东西

附言这在过去有效，所以我假设它与 SSH 密钥有关

错误:

解决方案

在日志中您会看到以下文本:

<上一页>(...)请联系您的系统管理员.在/root/.ssh/known_hosts 中添加正确的主机密钥以消除此消息./root/.ssh/known_hosts:1 中的违规 ECDSA 密钥删除:ssh-keygen -f "/root/.ssh/known_hosts" -R gitlab.site.orggitlab.site.org 的 ECDSA 主机密钥已更改，您已要求严格检查.主机密钥验证失败.

所以这是执行那里建议的命令的问题:

ssh-keygen -f "/root/.ssh/known_hosts" -R gitlab.site.org

I've got root access to our production server and I want to deploy the latest version in git to the server but I'm running into the error below when I "git pull" on the folder I want to update.

I've browsed around a bit, but can't find a clear answer on what to do..

The staging server runs on the same machine, but just in a different folder and when I pull on that folder it all goes fine.

I'm not very experienced when it comes to Linux, so please help me out with a clear answer on how to fix :-)

Otherwise I have access to anything I need

p.s. This has worked in the past, so I'm assuming it's got something to do with the SSH key

Error:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.

ECDSA host key for gitlab.site.org has changed and you have requested strict checking.
Host key verification failed.

解决方案

In the log you see the following text:

(...)

Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /root/.ssh/known_hosts:1
remove with: ssh-keygen -f "/root/.ssh/known_hosts" -R gitlab.site.org
ECDSA host key for gitlab.site.org has changed and you have requested strict checking.
Host key verification failed.

So it is a matter of performing the command that is suggested there:

ssh-keygen -f "/root/.ssh/known_hosts" -R gitlab.site.org
