1.下载一个安装包哦
在mac下安装git，首先下载一个git安装包，这里我选的是git-1.9.3.tar ，
因为这是比较新的一个版本，
网址是 https://www.kernel.org/pub/software/scm/git/
2. 在一个你喜欢的文件夹里解压一下安装包
打开terminal终端，进入安装包所在的文件夹之后执行以下的解压命令
$ tar -xf git-1.9.3.tar
3. 编译安装的命令如下
$ cd git-1.9.3
$ ./configure –prefix=/usr/local
$ make
$ sudo make install
4.查看一下git的安装路径
$which git
这里会得到路径/usr/local/bin/git
祝贺你已经安装完啦。以下来配置ssh连接吧
1.生成ssh的key
$ ssh-keygen -t rsa -C aaaa@163.com （后面的是git上注册的邮件哦）
$ vim id_rsa.pub (用vim命令打开文件可以复制一下啦)
不明白的同学可以看下面完的完整操作记录如下哦
angeladeMacBook-Air:.ssh angela$ ssh-keygen -t rsa -C aaaaa@163.com
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/angela/.ssh/id_rsa): key
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
angeladeMacBook-Air:.ssh angela$ ssh-keygen -t rsa -C aaaaa@163.com
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/angela/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/angela/.ssh/id_rsa.
Your public key has been saved in /Users/angela/.ssh/id_rsa.pub.
The key fingerprint is:
0e:70:c0:67:4b:08:15:b3:37:d9:b9:9a aaaaa@163.com
The key’s randomart image is:
+–[ RSA 2048]—-+
| .+=o |
| o++o |
| o+=.. |
| +.. . |
| o=.. |
| E+o |
+—————–+
2.登录github设置一下账户里的ssh key
在登录后直接点击右上方的工具按钮，也就是页面最上方从右边数第二个按钮（Account settings）
或者直接点击下面的网址
https://github.com/settings/ssh
进入Account setting之后，页面左侧有一列菜单，里面有一项是 SSH keys，点击后页面右侧会有add SSH keys的选项，点击后就可以把之前vim id_rsa.pub之后的内容粘贴过来啦。
3 已经配好啦，现在就可以回终端里测试一下啦。
angeladeMacBook-Air:.ssh angela$ ssh git@github.com
The authenticity of host ‘github.com (192.30.xxx .xxx)’ can’t be established.
RSA key fingerprint is 16:27:ac::63:1b:56:4d:eb:df:a68.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘github.com,192.30.xxx.xxx’ (RSA) to the list of known hosts.
PTY allocation request failed on channel 0
Hi aaaaaa! You’ve successfully authenticated, but GitHub does not provide shell access.
Connection to github.com closed.
完成啦，现在github和本地的git就可以顺利的连接啦，本地的代码就可以上传git仓库啦。
