自建了 gitlab，要如何配置 ssh 的密钥？

ssh-keygen 同时生成了公钥和私钥，私钥只留在机器上，上传公钥之后直接用就可以了

@ahaooahaz #1 但是 push 的时候提示 Permission denied (publickey)。不知道是什么原因，这个要怎么排查问题😭

... ssh-keygen 生成的时候既有公钥也有私钥。

gitlab 太重了，我选 gitea

ssh -T -v git@your-gitlab.com

ssh -T -v git@your-gitlab.com

看看有没有用上你的私钥。

一个手抖发出去了

@gegeligegeligo 是不是贴错 key 文件了，是那个 id_rsa.pub 文件的内容。要不就检查下仓库是否开了 push 权限或者用户权限不对

开 ssh 让我上去看看

@IvanLi127 #6 这个 git@your-gitlab.com 要怎么改，比如我的服务器地址是 192.168.2.2 ，端口是 30001

@8888k666 ssh 哥换号了？🤣

编辑~/.ssh/config

# gitlab
Host gitlab
HostName your-gitlab.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/your-gitlab-private-key

@gegeligegeligo #9 ssh -T -v -p 30001 [email protected]

@storyxc #11 还是不行，Permission denied (publickey).

@IvanLi127 #12 输出是这样的：

不知道为什么提示了 Host '[192.168.5.235]:30001' is known and matches the ED25519 host key ，但是还是 Permission denied

😭😭😭help me 这是为什么

~/.ssh/config 文件的配置里加 User git

ssh 用户名固定是 git ，不会是别的用户名，通常不能省略。
ssh -T -v -p 30001 [email protected]
看上去私钥文件没放错地方 /c/Users/99192/.ssh/id_ed25519 ,你要上传的是 /c/Users/99192/.ssh/id_ed25519.pub

之前也遇到了同样的问题。不知道楼主解决了没有。你是不是部署的时候，修改了 gitlab 的 22 端口？如果是的话，要么改回 22 端口。要么修改一下项目的 remote 地址，指定端口号，例如：ssh://git@xxxxxx:2222/abc/def 2222 是你修改的端口号。
