Git 的日常工作用法

GIT 配置

  • 生成SSH公鑰
cd ~/.ssh
ls
authorized_keys2  id_dsa       known_hosts
config            id_dsa.pub

關鍵是看有沒有用 something 和 something.pub 來命名的一對檔案，這個 something 通常就是 id_dsa 或 id_rsa。有 .pub 字尾的檔案就是公鑰，另一個檔案則是金鑰。假如沒有這些檔案，或者乾脆連 .ssh 目錄都沒有，可以用 ssh-keygen 來建立

ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/schacon/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/schacon/.ssh/id_rsa.
Your public key has been saved in /Users/schacon/.ssh/id_rsa.pub.
The key fingerprint is:
43:c5:5b:5f:b1:f1:50:43:ad:20:a6:92:6a:1f:9a:3a schacon@agadorlaptop.loca

它先要求你確認儲存公鑰的位置（.ssh/id_rsa），然後它會讓你重複一個密碼兩次，如果不想在使用公鑰的時候輸入密碼，可以留空。
注：使用git指使用git clone從遠端倉庫拉專案 或git push到遠端倉庫

  • 檢視本地公鑰
cd ~/.ssh
cat id_dsa.pub

  • 本地全域性設定使用者名稱和郵箱
git config --global user.name "zhangjianhui"
git config --global user.email "309078303@qq.com"
  • 檢視使用者名稱
git config user.name
  • 檢視郵箱
git config user.email
  • 配置遠端倉庫

這裡以alicode為例
登入完成後左側選單選擇 專案->設定->SSH公鑰
將本地ssh公鑰新增進去即可
image 個人設定

image SSH公鑰

  • 新增遠端倉庫
    這裡指定了遠端倉庫別名為 my 
    git remote add my git://github.com/paulboone/ticgit.git
  • 檢視遠端倉庫
git branch -a
* master
  my
  remotes/origin/HEAD -> origin/master
  remotes/origin/master
