配置用户名和邮箱

git config --global user.email "邮箱"
git config --global user.name "用户名"

SSH密钥生成

ssh-keygen -t rsa
cat ~/.ssh/id_rsa.pub

单远程多URL配置（懒人必备）

# 初始化远程仓库
git remote add origin https://github.com/你的用户名/仓库名.git

# 添加Gitee地址
git remote set-url --add origin https://gitee.com/你的用户名/仓库名.git

# 验证配置
git remote -v

origin  https://github.com/your-username/your-repo-name.git (fetch)
origin  https://github.com/your-username/your-repo-name.git (push)
origin  https://gitee.com/your-username/your-repo-name.git (push)  # 如果设置了同步推送
gitee   https://gitee.com/your-username/your-repo-name.git (fetch)
gitee   https://gitee.com/your-username/your-repo-name.git (push)
