push代码到github

• 安装git
  

  
   $ git
   The program 'git' is currently not installed. You can install it by typing:
   sudo apt-get install git
   

  上述表明没有安装git
  安装git: sudo apt-get install git

• 安装完成后配置信息:
  

  
   $ git config --global user.name "Your Name"
   $ git config --global user.email "[email protected]"
   

• 配置 SSH
  查看本地是否已经生成了ssh key(包含了id_rsa 以及id_rsa.pub): ~/.ssh
  没有就需要生成ssh key:
  

  
   $ ssh-keygen -t rsa -C "[email protected]"
   

  
  然后一直回车(有密码则需输入密码)
  查看是否配置成功:
  

  
   $ cd ~/.ssh
   $ ls
   $ id_rsa id_rsa.pub
   

  
  如果有id_rsa和id_rsa.pub两个文件则生成了ssh key,然后通过cat ~/.ssh/id_rsa.pub查看公钥内容,然后添加到github上的SSH Keys 中;

• 创建本地版本仓库
  1.在合适的位置创建一个空目录
  

  
   $ mkdir learngit
   $ cd learngit
   $ pwd
   /Users/desk/learngit
   

  
  也可以选择一个已有的项目文件夹, cd到当前文件夹下
  2.通过git命令 git init 把当前目录变成git可以管理的仓库:
  

  
   $ git init
   Initialized empty Git repository in /Users/desk/learngit/.git/
   

• 提交文件到仓库
  

  
   $ git add readme.txt
   $ git commit -m "提交了一个文件"
   

  
  上面两步可以合并一步: commit -a 然后再用vim编辑提交说明
  添加全部: git add .

• 添加远程仓库
  1.先在github上创建一个仓库并拷贝地址如:[email protected]:MrXiaxia/test.git
  2.然后关联本地仓库:$ git remote add origin [email protected]:MrXiaxia/test.git
  3.把本地库的内容推送到远程库: $ git push -u origin master
  4.首次提交推送需加上 -u ,以后不用;
  5.如出现以下错误:
  

  
   git push -u origin master
   To [email protected]:MrXiaxia/test.git
   ! [rejected] master -> master (non-fast-forward)
   error: failed to push some refs to '[email protected]:MrXiaxia/test.git'
   hint: Updates were rejected because the tip of your current branch is behind
   hint: its remote counterpart. Integrate the remote changes (e.g.
   hint: 'git pull ...') before pushing again.
   hint: See the 'Note about fast-forwards' in 'git push --help' for details.
   

  
  可以尝试用: git pull 或者git push --force origin master解决

• 从git上克隆项目到本地

//类似SVN 的 checkout
$ git clone [email protected]:sharlley/test.git

• 更新代码

//类似SVN 的 update
$ git pull

待续!
