我知道最初的问题列出了Cygwin，但这是CentOS的解决方案:

curl http://curl.haxx.se/ca/cacert.pem -o /etc/pki/tls/certs/ca-bundle.crt

设置SSL验证为false时在windows上克隆:

    git -c http.sslVerify=false clone http://example.com/e.git

如果你想克隆而不无聊你的全局设置。

如果你只想在github.com上使用Cygwin git客户端，有一种更简单的方法，而不必经历下载、提取、转换和分割证书文件的麻烦。按以下步骤进行(我假设Windows XP与Cygwin和Firefox)

In Firefox, go to the github page (any) click on the github icon on the address bar to display the certificate Click through "more information" -> "display certificate" --> "details" and select each node in the hierarchy beginning with the uppermost one; for each of them click on "Export" and select the PEM format: GTECyberTrustGlobalRoot.pem DigiCertHighAssuranceEVRootCA.pem DigiCertHighAssuranceEVCA-1.pem github.com.pem Save the above files somewhere in your local drive, change the extension to .pem and move them to /usr/ssl/certs in your Cygwin installation (Windows: c:\cygwin\ssl\certs ) (optional) Run c_reshash from the bash.

就是这样。

当然，这只安装一个证书层次结构，你需要的github。当然，您可以将此方法用于任何其他站点，而不需要安装200个您(不一定)信任的站点。

我在必须管理的协作开发平台上配置Git时遇到了同样的问题。

解决方法:

I've Updated the release of Curl installed on the server. Download the last version on the website Download page of curland follow the installation proceedings Installation proceedings of curl Get back the certificate of the authority which delivers the certificate for the server. Add this certificate to the CAcert file used by curl. On my server it is located in /etc/pki/tls/certs/ca-bundle.crt. Configure git to use this certificate file by editing the .gitconfig file and set the sslcainfo path. sslcainfo= /etc/pki/tls/certs/ca-bundle.crt On the client machine you must get the certificate and configure the .gitconfig file too.

我希望这对你们中的一些人有所帮助。

在CentOS 5上。X，一个简单的yum update openssl更新了openssl包，更新了系统ca-bundle。CRT文件，帮我解决了这个问题。

其他发行版可能也是如此。

我使用apt-cyg(一个类似于apt-get的伟大安装程序)来解决这个问题 轻松下载ca-certificates(包括Git等):

apt-cyg install ca-certificates

注意:apt-cyg需要先安装。你可以在Windows上这样做 命令行:

cd c:\cygwin
setup.exe -q -P wget,tar,qawk,bzip2,subversion,vim

关闭Windows cmd，打开Cygwin Bash:

wget rawgit.com/transcode-open/apt-cyg/master/apt-cyg
install apt-cyg /bin
