这个问题已经被问了无数次，但总是与公共git服务器（例如github）结合使用。我正在设置自己的私有git服务器，似乎一切正常，直到尝试使用以前提交并推送的子模块克隆项目为止。
关于github询问此问题时，答案总是似乎是需要生成密钥对，并且需要向github注册公共密钥。我很乐意在我的私人git服务器上注册我的公钥，但是我找不到关于此的任何文档。可能吗甚至将git-scm.com漏斗中的文档都存储到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。我已经完成了三个项目，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，提交和推送，但是当我尝试使用--recurse-submodules克隆它（或者先不进行子模块初始化/更新）时，子模块将失败。但是，我可以在主项目范围之外克隆子模块。
我一直在鬼混网络设置，而Pi更改了IP地址几次。因此，当我遇到问题时，我会设置一个指向路由器的DNS条目，并向路由器中的Pi添加端口转发规则，这样我就可以有效地从世界各地访问我的私有服务器。由于URL发生了变化，并且不想在某个地方留下旧URL，因此我只是再次启动了所有三个项目，但这对我没有帮助。
这是怎么回事？以下日志已匿名。 ：）
更新1：克隆子模块时，身份验证出现问题。当克隆子模块作为主项目克隆的一部分时，/ var / log / auth.log显示失败的登录：
Jan 13 15:07:56 raspberrypi sshd[3148]: Failed password for git from 192.168.1.18 port 62855 ssh2
我这样做的场景不仅显示了错误，而且还成功地从主项目的上下文中克隆了子模块：

答案 0 :(得分：2)
也许使用git守护程序或http（s）可行？要尝试git daemon
git daemon has no authentication，因此不会询问密码，这意味着访问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：我不确定如何设置它，因为您不需要密码。
如果您的服务器依赖SSH，则需要将您的公钥（~/.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（假设您不需要私钥）密码保护）
ssh-copy-id git@yourserver
如果您的服务器使用的是https服务器，则需要通过Git credential storage（例如，在Windows客户端上为using the Microsoft GCM）来缓存凭据（用户名/密码）
