Gitlab：无法使用 SSH 密钥或 HTTPS 连接

Question

我正在做一个项目，需要将 Gitlab 项目克隆到我的计算机上。我在虚拟机中运行 CentOS 6。我无权访问 Gitlab 服务器或其信息，因为它属于第三方。

SSH 问题

我尝试了多种创建 ssh 密钥的方法，包括但不限于：

ssh-keygen -t rsa -C "Gitlab" -b 4096
ssh-keygen -t rsa -C "GitLab" -b 2048
ssh-keygen

我从来没有设置过密码。我以适当的方式将/home/jchambers/.ssh/id_rsa.pub 复制到Gitlab，但这是我的结果：

$ git clone git@localhost:Project/Project_stuff.git
Initialized empty Git repository in /home/jchambers/Project/Project_stuff/.git/
git@localhost's password: 
Permission denied, please try again.

我从未设置密码，我的 Gitlab 密码和我的计算机登录密码都不是这里期望的密码。根据this question，我跑了ssh -vT git@localhost：

$ ssh -vT git@localhost

并更新了这些权限：

chmod 700 /home/git/.ssh
chmod 600 /home/git/.ssh/authorized_keys

我不明白公钥身份验证部分有什么问题。

编辑*

根据我收到的答案，我更改了命令中的主机名，使其成为：

$ git clone jessica.chambers@my-gitlab.gitlab-platform.net:Project/Project_stuff.git
Initialized empty Git repository in /home/jchambers/Project/Project_stuff/.git/
ssh: connect to host my-gitlab.gitlab-platform.net port 22: Connection timed out
fatal: The remote end hung up unexpectedly

我也再次运行了这个，但连接似乎总是超时：

$ ssh -vT jessica.chambers@my-gitlab.gitlab-platform.net
OpenSSH_5.3p1, OpenSSL 1.0.1e-fips 11 Feb 2013
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug1: Connecting to my-gitlab.gitlab-platform.net [12.34.567.89] port 22.
debug1: connect to address 12.34.567.89 port 22: Connection timed out
ssh: connect to host my-gitlab.gitlab-platform.net port 22: Connection timed out

HTTPS 问题

由于 SSH 的情况似乎没有结果，我尝试了 HTTPS 方法。它最初没有工作，所以根据另一个问题，我做了以下更改：

sudo yum install ca-certificates
update-ca-trust force-enable

这没什么区别。这是我尝试通过 HTTPS 克隆时得到的结果：

$ git clone https://my-gitlab.gitlab-platform.net/gitlab/Project/Project_stuff.git
Initialized empty Git repository in /home/jchambers/Project/Project_stuff/.git/
error:  while accessing https://my-gitlab.gitlab-platform.net/gitlab/Project/Project_stuff.git/info/refs

fatal: HTTP request failed

我的互联网连接，虽然在代理之后，但可以正常工作（例如，我可以通过yum 安装，并使用网络浏览器）。 Gitlab 项目确实需要登录，所以也许我需要在某处输入？

如果有人可以为我指出 SSH 问题或 HTTPS 问题的正确方向，那将非常有帮助。

Answer 1

我相信你的 GitLab 的 SSH 端口不是 22。在你使用 SSH 的 URL 中，你默认使用端口 22，我猜测是你的服务器的 SSH 守护进程在回答，而不是 GitLab - 因此你的公钥没有不工作。 HTTPS 也一样，我假设默认端口不是 443。

如果您可以分享有关 GitLab 如何安装和运行的更多详细信息 - 可以为您提供更多指导。
