1.ubuntu下安装git环境

• ubuntu 16.04已经自带git ，可以通过下列命令进行安装与检测是否成功安装

1. sudo apt-get inst all git 　//安装  
   

   ---

2. //git命令出现代表安装成功（为考证） 
   

   ---

3. root@forest-E351:/# git 
   

   ---

4. usage: git [--version] [--help] [-C <path>] [-c name=value] 
   

   ---

5. [--exec-path[=<path>]] [--html-path] [--man-path] [--info-path] 
   

   ---

6. [-p | --paginate | --no-pager] [--no-replace-objects] [--bare] 
   

   ---

7. [--git-dir=<path>] [--work-tree=<path>] [--namespace=<name>] 
   

   ---

8. <command> [<args>] 
   

   ---

9. ---

10. These are common Git commands used in various situations: 
    

    ---

11. ---

12. start a working area (see also: git help tutorial) 
    

    ---

13. clone Clone a repository into a new directory 
    

    ---

14. init Create an empty Git repository or reinitialize an existing one

• 打通本地git与github之间的连接
  
  设置git的user.name和user.email,便于后面定位git commit的操作对象,姓名和邮箱不需要与github对应，若不操作，则不能进行本地git commit提交。

1. git config --global user.name "我填写的是github上用户名称" 
   

   ---

2. git config --global user.email "我填写github注册邮件"

• 生成ssh key，用于本地连接上github
  • 查看是否已经有了ssh密钥：cd ~/.ssh,如果没有密钥则不会有此文件夹，有则备份删除。
  • 生存密钥：$ ssh-keygen -t rsa -C “h××@163.com”
    
    注：ssh-keygen - 生成、管理和转换认证密钥
    
    ssh-keygen [-q] [-b bits] -t type [-N new_passphrase] [-C comment] [-foutput_keyfile]
    
    -t 指定要创建的密钥类型。可以使用：“rsa1”(SSH-1) “rsa”(SSH-2) “dsa”(SSH-2)
    
    -C 提供一个新注释 查看公钥文件，最后就是你-Ｃ填写的邮箱
    
    按3个回车，密码为空,最后得到了两个文件：id_rsa和id_rsa.pub,终端会出现如下结果：

1. Your identification has been saved in /home/forest/.ssh/id_rsa. 
   

   ---

2. Your public key has been saved in /home/forest/.ssh/id_rsa.pub. 
   

   ---

3. The key fingerprint is: 
   

   ---

4. ……………… 
   

   ---

5. cat ~/.ssh/id_rsa.pub 
   

   ---

6. ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQD1MLePx7

• 多次生成秘钥会使得目录下自动生成另外一种命名公钥和私钥，如y和y.pub

• 上传public key到Github账户
  
  1.登陆github
  
  2.点击右上方的accounting settings
  
  3.选择SSH KEY
  
  4.点击添加ssh key 即为～/.ssh/id_rsa.pub 中的内容
  
  修改～/.ssh/config Host github.com Hostname ssh.github.com Port 44
  
  不修改也可以 直接使用ssh -T git@github.com 测试即可,出现以下结果说明连接成功

1. Hi wowforestwow! You've successfully authenticated,  
   

   ---

2. but GitHub does not provide shell access. 
   

   ---

3. Connection to github.com closed
