使用碼雲帶來的好處：

• 程式碼共享
• 檔案恢復
• 原始碼維護
• 版本控制

常見版本控制系統有Git、SVN、CVS、Git、Mercurial，目前主流使用的最多的就是git和svn，下面是這兩種版本控制系統的比較：

1. GIT是分散式的，SVN是集中式管理；
2. GIT把內容按元資料方式增量儲存，而SVN是按檔案； <.svn .git >
3. GIT分支和SVN的分支不同；
4. GIT的內容完整性要優於SVN：
5. git內容儲存使用的是SHA-1雜湊演算法；
6. SVN有一個全域性的整數編號，而git則是一個SHA-1值作編號：
7. SVN控制粒度可以到某個目錄（當然很少這樣做）;而git一般是整個專案；

一、建立專案

 1. 點選“+”->"新建專案"
 2. 填寫歸屬->填寫名稱->路徑自動匹配->介紹(非必填)->選擇程式語言(如C)->新增.gitignore->加密方式(如GPL v2)->相應填寫是否公開->儲存
 3. (可選)開啟svn訪問：點進專案->管理->基本設定->啟用svn訪問

二、公鑰管理

開發者向碼雲版本庫寫入最常用到的協議是 SSH 協議，因為 SSH 協議使用公鑰認證，可以實
現無口令訪問，而若使用 HTTPS 協議每次身份認證時都需要提供口令。

1.若伺服器沒有安裝git服務，首先安裝

[root@VM_83_82_redhat ~]# yum install git git-gui

2.對git進行全域性配置

[yanhuan@VM_83_82_redhat ~]$ git config --global user.name"yanhuan"
[yanhuan@VM_83_82_redhat ~]$ git config --global user.email"*****@foxmail.com"
//使用者名稱和郵箱應為自己實際姓名而非登入名

3.生成SSH祕鑰

[[email protected]_83_82_redhat ~]$ ssh-keygen -t rsa -C "*****@foxmail.com"
 
  //對應上方郵箱
Generating public/private rsa key pair.
Enter file in which to save the key (/home/yanhuan/.ssh/id_rsa):       //選擇祕鑰儲存路徑
Created directory '/home/yanhuan/.ssh'. 
Passphrases do not match.  Try again.
Enter passphrase (empty for no passphrase):     //linux賬號的密碼
Enter same passphrase again: 
Your identification has been saved in /home/yanhuan/.ssh/id_rsa.
Your public key has been saved in /home/yanhuan/.ssh/id_rsa.pub.
The key fingerprint is:
3b:2b:69:61:f1:40:77:c0:3a:ff:e8:07:3f:58:1c:cd *****@foxmail.com
The key's randomart image is:
+--[ RSA 2048]----+
|       ...       |
|      . o .      |
|     . o . o     |
|      =   . E    |
|       *S. .     |
|      o +.o      |
|     . ooB       |
|      + oo=      |
|     . oo. .     |
+-----------------+

4.上傳祕鑰到碼雲

[[email protected]_83_82_redhat ~]$ cat ~/.ssh/id_rsa.pub               //檢視祕鑰檔案
ssh-rsa AAAA************705R2UZ ******@foxmail.com

設定->SSH公鑰->新增

5.測試是否連上SVN

[[email protected]_83_82_redhat ~]$ ssh -T [email protected]
The authenticity of host 'git.oschina.net (120.55.226.24)' can't be established.
ECDSA key fingerprint is 27:e5:d3:f7:2a:9e:eb:6c:93:cd:1f:c1:47:a3:54:b1.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'git.oschina.net,120.55.226.24' (ECDSA) to the list of known hosts.
Enter passphrase for key '/home/yanhuan/.ssh/id_rsa':                   //linux密碼
Welcome to Gitee.com, yanhuan!                                          //成功
[[email protected]_83_82_redhat ~]$ 

三、下載

1.git下載

[[email protected]_83_82_redhat ~]$ git clone [email protected]:************.git
Cloning into 'FL2440KaiFaBan'...
The authenticity of host 'gitee.com (120.55.226.24)' can't be established.
ECDSA key fingerprint is 27:e5:d3:f7:2a:9e:eb:6c:93:cd:1f:c1:47:a3:54:b1.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'gitee.com' (ECDSA) to the list of known hosts.

2.svn下載

注意: 在碼雲上使用git管理的專案，svn不能管理空資料夾，只能管理檔案:

[root@VM_83_82_redhat ~]# yum install subversion                   //首先要有svn

[yanhuan@VM_83_82_redhat ~]$ svn co svn://gitee.com/**********     //svn下載地址
Authentication realm: <svn://gitee.com:3690> gitee.com
Password for 'yanhuan':                                            //linux密碼
