安装git

apt-get install git -y

进入目录后初始化

git init

排除不需要备份的文件和目录

在根目录下创建.gitignore文件，里面的文件或目录不会被上传到github. 例：

public
themes
dev
.git
.DS_Store
*.bak
*_bak
*.old
*.log

使用 SSH 密钥登录 GitHub

git config --global user.name "username"
git config --global user.email "username168@gmail.com"
ssh-keygen -t rsa -C 'username@gmail.com'

然后使用

cat /root/.ssh/id_rsa.pub

把里面的文本全部复制到 https://github.com/username/branchname/settings/keys Add deploy key

ssh -T git@github.com

测试是否连接成功

推送到github

git commit -m "自定义描述"
git remote add origin git@github.com:username/branchname.git
git push -u origin master

git push错误提示

使用git push -u origin master时弹出错误提示

  • src refspec master does not match any.
error: src refspec master does not match any.
error: failed to push some refs to 'git@github.com:username/branchname.git'

然后用如下方法解决了：

git add .
git commit -m "write your meaaage"
  • ERROR: Repository not found.
ERROR: Repository not found.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

解决方案是

git remote set-url origin git@github.com:username/branchname.git

更新push

以后当有更新时，使用以下三步曲上传。

git add .
git commit -m "自定义描述" 
git push -u origin master
