今天花了一個下午的時間來玩GitHub，遇到一些問題，基本靠官方wiki和Google解決了。現在把過程記錄下來。
一、註冊一個GitHub賬號
二、新建一個倉庫
每次向GitHub提交的代碼都會被放到一個倉庫（repo）。爲了把你的項目放到GitHub上，你需要有一個GitHub倉庫來“入住”。
點擊新倉庫
在新的頁面裏填上倉庫的名稱（因爲已經創建過了，所以爲提示衝突）：
點擊創建後就OK了！
三、安裝和配置git
使用yum安裝
yum -y install git
完成後查看是否成功
[root@localhost ~]# git --version git version 1.7.1
可以看到安裝成功了，如果使用源碼可以安裝最新版本的。
接着就要設置用戶名和Email了，Email最好和註冊時候的一樣。
$ git config --global user.name "Your Name Here" # Sets the default name for git to use when you commit $ git config --global user.email "[email protected]" # Sets the default email for git to use when you commit
上面的內容都寫在配置文件~/.gitconfig裏了
恭喜，到這裏，基本Git和GitHub都配置好了！
四、創建和提交項目
這裏給官方提供的例子吧,Hello-World爲項目名稱。
$ mkdir ~/Hello-World # Creates a directory for your project called "Hello-World" in your user directory $ cd ~/Hello-World # Changes the current working directory to your newly created directory $ git init # Sets up the necessary Git files # Initialized empty Git repository in /Users/you/Hello-World/.git/ $ touch README # Creates a file called "README" in your Hello-World directory
如果已經有項目了，就只用切換到項目目錄，然後git init。
接着向Git提交修改
$ git add README # Stages your README file, adding it to the list of files to be committed $ git commit -m 'first commit' # Commits your files, adding the message "first commit"
這裏所有的更改都只是在本地的。Push之後纔會提交到GitHub保存：
$ git remote add origin https://github.com/username/Hello-World.git # Creates a remote named "origin" pointing at your GitHub repository $ git push origin master # Sends your commits in the "master" branch to GitHub
成功之後就可以在網頁上看到添加的文件了：
但是我這邊沒有這麼一帆風順，主要是在最後一步出了問題：
向GitHub提交時遇到403錯誤：
root@localhost InfoView4CentOS]# git remote add origin https://github.com/callmepeanut/InfoView4CentOS.git [root@localhost InfoView4CentOS]# git push origin master error: The requested URL returned error: 403 Forbidden while accessing https://github.com/callmepeanut/InfoView4CentOS.git/info/refs fatal: HTTP request failed
根據《github初試-403錯誤》將地址由https改爲ssh方式
git remote set-url origin https://[email protected]/callmepeanut/InfoView4CentOS.git
Push之後出現新的錯
[root@localhost InfoView4CentOS]# git push origin master (gnome-ssh-askpass:3422): Gtk-WARNING **: cannot open display:
Google了下，是SSH_ASKPASS這個環境變量出的問題，unset掉就OK了。
ho 'unset SSH_ASKPASS' >> ~/.bashrc && source ~/.bashrc
終於連接上了，輸入yes後居然又出現了問題
[root@localhost InfoView4CentOS]# git push origin master The authenticity of host 'github.com (192.30.252.129)' 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 Warning: Permanently added 'github.com,192.30.252.129' (RSA) to the list of known hosts. Permission denied (publickey). fatal: The remote end hung up unexpectedly
繼續Google，按照《訪問[email protected]出現Permission denied (publickey).的解決辦法》成功得添加了SSH key，測試一下：
[root@localhost InfoView4CentOS]# ssh -T [email protected] Warning: Permanently added the RSA host key for IP address '192.30.252.130' to the list of known hosts. Hi callmepeanut! You've successfully authenticated, but GitHub does not provide shell access.
成功連接上了，繼續PUSH！沒想到還是未能成功：
[root@localhost InfoView4CentOS]# git push origin master Warning: Permanently added the RSA host key for IP address '192.30.252.131' to the list of known hosts. ERROR: Repository not found. fatal: The remote end hung up unexpectedly
查看了官網的幫助文檔：https://help.github.com/articles/error-repository-not-found ，最大的可能是拼寫不正確，去主頁看了下，確實InfoView4CentOS的V小寫了，於是把原來的倉庫刪掉，重新建立了一個，接着PUSH：
[root@localhost InfoView4CentOS]# git push origin master Counting objects: 6, done. Compressing objects: 100% (5/5), done. Writing objects: 100% (6/6), 1.32 KiB, done. Total 6 (delta 0), reused 0 (delta 0) To ssh://[email protected]/callmepeanut/InfoView4CentOS.git * [new branch] master -> master
噢耶，成功了！
