git預設push需要填寫賬號密碼才能成功，通過配置賬號和ssh可以實現直接推送，節省時間。步驟如下:

1. 開啟.git/config,找到[remote "origin"]欄下的url，將https認證改成git認證，格式如下

[email protected]:xxx/learngit.git

xxx是賬號

2開啟家目錄下.ssh目錄，如果存在id.rsa,id.rsa.pub,表示已有金鑰生成，如果不用可直接刪除，重新生成。

ssh-keygen -t rsa -b 4096 -C "xxx"，一路回車

ssh-add ~/.ssh/id_rsa

3 開啟id_rsa.pub，複製公鑰資訊，開啟github的setting頁，ssh gpg keys選項，點選new ssh key，貼上公鑰資訊，輸入名稱，如cloud-key，點選提交。

測試方法，執行命令
 git push -u origin master

結果如下:
