如何在Windows下正常运行SSH-Agent

现有的答案没有一个能使我满意地解决这个问题。下面是微软的建议:

以管理员权限启动powershell控制台:

按Win Win开始菜单，输入powershell，按回车键

将Windows中包含的OpenSSH添加到PATH变量中:

setx PATH "c:/Windows/System32/OpenSSH/;$Env:PATH;" 

关闭powershell终端，打开一个新的。

输入以下命令，确保openssh代理作为服务在后台运行:

# enable automatic start
Get-Service ssh-agent | Set-Service -StartupType Automatic

# start it now
Start-Service ssh-agent

现在服务应该运行，你可以检查通过

Get-Service ssh-agent

将您的私钥加载到ssh-agent中，例如:

ssh-add $env:USERPROFILE/.ssh/id_rsa

现在您应该可以使用您的私钥，而不必每次都输入密码。

如果你在Windows下使用Git bash，你可以执行以下操作:

eval `ssh-agent -s`
ssh-add ~/.ssh/*_rsa

它会在第二个命令中要求传递短语，就是这样。你需要做的每一个额外的操作(曾经需要pass phrase)都不会要求你提供pass phrase(参见下面的屏幕截图中的例子):

我意识到这个问题在两年前就出现了，但我也有同样的问题，这里的几个答案并没有完全回答我的问题。以下是三个分步解决方案，具体取决于您是否使用TortoiseGit和msysgit。

第一种方案以Windows、msysgit、PuTTY为例。

Install msysgit and PuTTY as instructed. (Optional) Add PuTTY to your path. (If you do not do this, then any references to PuTTY commands below must be prefixed with the full path to the appropriate executable.) If you have not done so already, then generate a key hash as instructed at GitHub or as instructed by your Git host. Again, if you have not already done so, convert your key for use with PuTTY's pageant.exe using puttygen.exe. Instructions are in PuTTY's documentation, in this helpful guide, and several other places in cyberspace. Run PuTTY's pageant.exe, open your .ppk file ("Add Key"), and provide your passphrase for your key. Access Windows' environment variables dialog (Right-click on "Computer", Click on "Properties", Click on "Advanced system settings" or the "Advanced" tab, click on "Environment Variables"). Add the following environment variable: GIT_SSH=C:\full\path\to\plink.exe Replace "C:\full\path\to" with the full installation path to PuTTY, where plink.exe is found. It is probably best to add it to the "User variables" section. Also, make sure that the path you use to plink.exe matches the path you use for Pageant (pageant.exe). In some cases, you may have several installations of PuTTY because it might be installed along with other applications. Using plink.exe from one installation and pageant.exe from another will likely cause you trouble. Open a command prompt. If you are trying to connect to a git repository hosted at Github.com then run the following command: plink.exe git@github.com If the git repository you are trying to connect to is hosted somewhere else, then replace git@github.com with an appropriate user name and URL. (Assuming Github) You should be informed that the server's host key is not cached, and asked if you trust it. Answer with a y. This will add the server's host key to PuTTY's list of known hosts. Without this step, git commands will not work properly. After hitting enter, Github informs you that Github does not provide shell access. That's fine...we don't need it. (If you are connecting to some other host, and it gives you shell access, it is probably best to terminate the link without doing anything else.) All done! Git commands should now work from the command line. You may want to have pageant.exe load your .ppk file automatically at boot time, depending on how often you'll be needing it.

第二种方案假设Windows、msysgit和TortoiseGit。

TortoiseGit附带了PuTTY可执行文件和一个经过特别修改的plink版本(称为TortoisePlink.exe)，这将使事情变得更简单。

Install msysgit and TortoiseGit as instructed. If you have not done so already, then generate a key hash as instructed at GitHub or as instructed by your Git host. Again, if you have not already done so, convert your key for use with TortoiseGit's pageant.exe using TortoiseGit's puttygen.exe. Instructions are in PuTTY's documentation, in the helpful guide linked to in the first solution, and in several other places in cyberspace. Run TortoiseGit's pageant.exe, open your .ppk file ("Add Key") and provide your passphrase for your key. Access Windows' environment variables dialog (Right-click on "Computer", Click on "Properties", Click on "Advanced system settings" or the "Advanced" tab, click on "Environment Variables"). Add the following environment variable: GIT_SSH=C:\full\path\to\TortoisePlink.exe Replace "C:\full\path\to" with the full installation path to TortoiseGit, where TortoisePlink.exe is found. It is probably best to add it to the "User variables" section. Also, make sure that the path you use to TortoisePlink.exe matches the path you use for Pageant (pageant.exe). In some cases, you may have several installations of PuTTY because it might be installed along with other applications. Using TortoisePlink.exe from the TortoiseGit installation and pageant.exe from another installation of a different application (or from a standalone PuTTY installation) will likely cause you trouble. All done! Git commands should now work from the command line. The first time you try to connect to your git repository you will probably be informed that the server's host key is not cached, and asks if you trust the server. Click on "Yes". (This is TortoisePlink.exe in action.) You may want to have pageant.exe load your .ppk file automatically at boot time, depending on how often you'll be needing it.

第三种方案假设Windows、msysgit和本机命令提示符。

安装msysgit 确保允许在MS-DOS命令提示符上使用git 运行start-ssh-agent 输入SSH密码 全部完成!Git命令现在应该在本机命令提示符中工作。

确保你的~/。Ssh /config不包含

UseKeychain是的

防止ssh-add持久化到ssh-agent。

如果您为密钥文件设置了密码，则在连接时始终需要输入该密码。如果你创建了一个无密码密钥，那么你就不必每次都输入它，但是，任何访问你的密钥文件的人现在都可以连接到你的github帐户。

Ssh-agent也可以工作。试着运行它，看看它是否会记住你的密码。

我意识到这个问题已经拖延了好几年，但我无意中发现了这个问题，试图找到一个解决方案，我发现了一些适合所有专业水平的东西，所以我想我应该分享一下。

GitHub提供了一个非常有用的安装程序，使一切都很好很简单:https://help.github.com/articles/caching-your-github-password-in-git/
