Generating a new SSH key

1. Open Terminal.

2. Paste the text below, substituting in your GitHub email address.

   ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
   

   This creates a new ssh key, using the provided email as a label.

   Generating public/private rsa key pair.
   

3. When you're prompted to "Enter a file in which to save the key," press Enter. This accepts the default file location.

   Enter a file in which to save the key (/Users/you/.ssh/id_rsa): [Press enter]
   

4. At the prompt, type a secure passphrase. For more information, see "Working with SSH key passphrases".

   Enter passphrase (empty for no passphrase): [Type a passphrase]
   Enter same passphrase again: [Type passphrase again]

Git配置SSH,并Push到GitHub上的相关流程

首先，你可以试着输入git，看看系统有没有安装Git

像上面的命令，有很多Linux会友好地告诉你Git没有安装，还会告诉你如何安装Git。

如果你碰巧用Debian或Ubuntu Linux，通过一条sudo apt-get install git就可以直接完成Git的安装，非常简单。

如果是其他Linux版本，可以直接通过源码安装。先从Git官网下载源码，然后解压，依次输入：./config，make，sudo make install这几个命令安装就好了。

安装完成后，还需要最后一步设置，在命令行输入：

然后我们需要配置SSH。

第1步：创建SSH Key。在用户主目录下，看看有没有.ssh目录，如果有，再看看这个目录下有没有id_rsa和id_rsa.pub这两个文件，如果已经有了，可直接跳到下一步。如果没有，打开Shell（Windows下打开Git Bash），创建SSH Key：

你需要把邮件地址换成你自己的邮件地址，然后一路回车，使用默认值即可，由于这个Key也不是用于军事目的，所以也无需设置密码。

如果一切顺利的话，可以在用户主目录里找到.ssh目录，里面有id_rsa和id_rsa.pub两个文件，这两个就是SSH Key的秘钥对，id_rsa是私钥，不能泄露出去，id_rsa.pub是公钥，可以放心地告诉任何人。

第2步：登陆GitHub，打开“Account settings”，“SSH Keys”页面：

然后，点“Add SSH Key”，填上任意Title，在Key文本框里粘贴id_rsa.pub文件的内容：

点“Add Key”，你就应该看到已经添加的Key：

为什么GitHub需要SSH Key呢？因为GitHub需要识别出你推送的提交确实是你推送的，而不是别人冒充的，而Git支持SSH协议，所以，GitHub只要知道了你的公钥，就可以确认只有你自己才能推送。

当然，GitHub允许你添加多个Key。假定你有若干电脑，你一会儿在公司提交，一会儿在家里提交，只要把每台电脑的Key都添加到GitHub，就可以在每台电脑上往GitHub推送了。

现在，我们根据GitHub的提示，在本地的learngit仓库下运行命令：

请千万注意，把上面的 cqcre 替换成你自己的GitHub账户名，否则，你在本地关联的就是我的远程库，关联没有问题，但是你以后推送是推不上去的，因为你的SSH Key公钥不在我的账户列表中。

添加后，远程库的名字就是origin，这是Git默认的叫法，也可以改成别的，但是origin这个名字一看就知道是远程库。

下一步，就可以把本地库的所有内容推送到远程库上：

好啦，静静等待git把你的代码Push上去吧~是不是很简单？

How to access my .ssh?

In the find file window, press Command-Shift-G. It'll ask you what folder to navigate to. Enter "~/.ssh" and press return.
