How to get the key for git cloning

May 17, 2023 am 09:02 AM

对于使用 git 进行代码管理的开发人员来说,git 克隆(clone)操作是非常常见的。通过克隆操作,开发者可以将一个远程仓库中的代码下载到本地进行开发和修改。而在进行 git 克隆的过程中,需要使用密匙来进行身份认证,以保证操作的安全性。本文将介绍如何生成和使用 git 克隆的密匙。

一、生成 Git 克隆的密匙

在进行 git 克隆操作时,需要先生成一对公钥和私钥,其中私钥需放置在本地计算机上,公钥则放置在远程仓库服务器上。具体生成方法如下:

  1. 打开终端或命令行,输入以下命令生成一对公钥和私钥:
ssh-keygen -t rsa -C "your_email@example.com"
Copy after login

注意:需要将 your_email@example.com 替换为你的邮箱地址。

  1. 接着会提示你输入密码等信息,按照提示一步步操作即可。

生成完成后,私钥默认存放于 ~/.ssh/id_rsa,公钥则存放于 ~/.ssh/id_rsa.pub

二、使用 Git 克隆的密匙

在生成密匙后,需要对 git 进行配置,使其可以使用密匙进行身份认证。

  1. 打开终端或命令行,输入以下命令设置 Git 用户名和邮箱:
git config --global user.name "Your Name"
git config --global user.email "your_email@example.com"
Copy after login

注意:需要替换 Your Nameyour_email@example.com 为你的名字和邮箱。

  1. 接下来,将公钥添加到远程仓库服务器上,具体操作方式取决于你所使用的远程仓库服务商。以 GitHub 为例,具体操作步骤如下:
  • 登录 GitHub 账户
  • 点击右上角头像,选择 Settings
  • 进入 SSH and GPG keys 页面
  • 点击 New SSH key 按钮
  • 输入一个自定义的标题(用于区分不同的密匙),将 id_rsa.pub 中的内容复制到 Key 一栏中
  • 点击 Add SSH key 完成添加
  1. 最后,可以通过以下命令进行 git 克隆操作:
git clone git@github.com:your_username/your_repository.git
Copy after login

其中,your_username 替换为你的 GitHub 用户名,your_repository 替换为你要克隆的仓库名称。

总之,在进行 git 克隆操作时,密匙的使用是不可或缺的。通过生成一对公钥和私钥,并将公钥添加到远程仓库服务器上,可以实现高效安全的代码管理。
