git - Git 子模块在从私有 git 服务器克隆时无法递归

问题描述

这个问题已经被问过无数次了，但总是与使用公共 git 服务器（如 github）结合使用。我正在设置我自己的私有 git 服务器，这似乎一切正常，直到我尝试使用我之前提交并自己推送的子模块克隆一个项目。

当关于 github 提出这个问题时，答案似乎总是需要生成密钥对，并且需要在 github 上注册公钥。我很乐意在我的私人 git 服务器上注册我的公钥，但我找不到任何关于此的文档。甚至可能吗？甚至来自 git-scm.com 的文档也汇集到了 github 参考中。

我的私人 git 服务器只不过是一个带有外部硬盘驱动器的 Raspberry Pi，运行 Raspbian lite。我做了三个项目，其中一个是主项目，另外两个作为子模块添加。我可以这样创建它，提交并推送，但是当我尝试使用 --recurse-submodules （或没有然后子模块初始化/更新）克隆它时，子模块失败。但是，我可以克隆主项目范围之外的子模块。

我一直在玩弄网络设置，并且 Pi 已经更改了几次 IP 号。当我因此遇到问题时，我设置了一个指向我的路由器的 DNS 条目，并为路由器中的 Pi 添加了一个端口转发规则，这样我就可以有效地从世界各地访问我的私人服务器。因为 URL 发生了变化，并且不想在某个地方出现旧 URL 的残余，所以我只是重新启动了所有三个项目，但这对我没有帮助。

这里发生了什么？以下日志已匿名。:)

更新 1：问题出在子模块被克隆时的身份验证中。/var/log/auth.log 在子模块被克隆作为主项目克隆的一部分时显示登录失败：

Jan 13 15:07:56 raspberrypi sshd[3148]: Failed password for git from 192.168.1.18 port 62855 ssh2

我这样做的场景显示了错误，并且从主项目的上下文中克隆子模块也成功了：

解决方案

也许使用 git daemon 或 http(s) 这可能有效？打算试试 git 守护进程

git daemon没有身份验证，因此不会询问密码，这意味着访问您的服务器的每个人都可以克隆存储库。

我不希望每个人都能够克隆我的存储库和 2：我不知道如何设置它不需要密码。

如果您的服务器依赖于 SSH，您需要将您的公钥 ( ~/.ssh/id_rsa.pub) 发布到git@yourserver:~git/.ssh/authorized_keys：任何克隆都不需要您输入任何密码（假设您的私钥不受密码保护）

ssh-copy-id git@yourserver

如果您的服务器使用的是 https 服务器，那么您需要通过Git 凭证存储（例如，在使用 Microsoft GCM的 Windows 客户端上）缓存您的凭证（用户名/密码）。
