MAC 下 Git的安装与基本配置

• 下载git版本源码：（前提是安装了xcode）
  

  http://kernel.org/pub/software/scm/git/

• 解压下载在安装包：
  

  tar xjvf git-1.8.4

   
• 编译  cd git-1.8.4
  

  ./configure --prefix=/usr/local
  make

   
• 安装
  

  sudo make install

   
• 检查安装git的版本
  

  git --version

   
• 查看git的安装路径
  

  which git

   
• 设置SSH
  

  //检查SSH key   
  cd ~/.ssh
  //备份已有的key  
  mkdir key_backup
  mv id_rsa*key_backup

• 生成SSH key 
  

  ssh-keygen -t rsa -C [e-mail]
  //备注：后面的邮箱为注册github账号的邮箱

     运行之后，生成SSH key

  Generating public/private rsa key pair.
  
           Enter file in which to save the key (/Users/chenyue123/.ssh/id_rsa): 
  
           Enter passphrase (empty for no passphrase):
     
           Enter same passphrase again:
  
           Your identification has been saved in yes.
  
           Your public key has been saved in id_rsa.pub.
  
           The key fingerprint is:
  
           fb:c4:b0:e0:47:fd:be:e0:fb:ea:73:ef:a8:29:d5:22 [e-mail]
  
           The key's randomart image is:
  
  +--[ RSA 2048]----+
  
  |                 |
  
  |                 |
  
  |                 |
  
  |         .       |
  
  |      . S ..     |
  
  |     . oE=o..    |
  
  |      . +o+..    |
  
  |       ..+.+..   |
  
  |         oOB=+o  |
  
  +-----------------+

   
•  将SSH key添加到GitHub

   

     登录到GitHub页面，找到
  
  

  Account Settings->SSH Public Keys->Add another key

      将生成的key(id_rsa.pub文件）内容copy到输入框中，save。

   

•  测试链接
  

  ssh [e-mail]

   运行结果显示
  

  The authenticity of host 'github.com (207.97.227.239)' can't be   
      established.
  
      RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
  
      Are you sure you want to continue connecting (yes/no)? yes

      Hi chenyue123! You've successfully authenticated, but GitHub does not provide shell access.
  
           Connection to github.com closed.

   
• 设置个人信息
  

  //设置github默认用户名
  git config --global user.name "chenyue123"
  //设置github默认用户邮箱
  git config --global user.email "[e-mail]"

• 开启终端输入git命令时显示颜色
  

  git config --global color.ui true

• 查看git默认的用户名和邮箱 
  

  //查看git的默认用户名
  git config user.name
  //查看git的默认邮箱
  git config user.email

   

  //打印结果分别为
  //用户名
  chenyue123
  //邮箱
  [e-mail]
