为 GitHub 设置 SSH 密钥_github如何设置ssh密钥

github如何设置ssh密钥

1. 起因

给自己的 github 改个名,顺便就给原来 Hexo 对应的仓库也改了个名。然后发现 ub='hexo clean && hexo generate && hexo deploy' 失败了,报错如下:

INFO  Deploying: git
INFO  Clearing .deploy_git folder...
INFO  Copying files from public folder...
INFO  Copying files from extend dirs...

} Something's wrong. Maybe you can find the solution here: %s https://hexo.io/docs/troubleshooting.html

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

好像我的 ssh 配置出问题了,想来那就重新配一遍吧,顺便记录下。

2. 配置过程

2.1 生成 SSH 密钥
ssh-keygen -t ed25519 -C "your_email@example.com"
  • 1

**注意:**如果您使用的是不支持Ed25519算法的遗留系统,请使用:

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"
  • 1
> Enter a file in which to save the key (/Users/YOU/.ssh/id_ALGORITHM): [Press enter]
> Enter passphrase (empty for no passphrase): [Type a passphrase]
> Enter same passphrase again: [Type passphrase again]å

这时候在 ~/.ssh/ 下应该看到如下文件:

image-20230715140759430

2.2 将 SSH 密钥添加到 ssh-agent
  1. 在后台启动 ssh-agent

    $ eval "$(ssh-agent -s)"
    > Agent pid 51024

  2. 打开文件 ~/.ssh/config ,然后修改文件以包含以下行

    Host github.com
      AddKeysToAgent yes
      IdentityFile ~/.ssh/id_ed25519
    
    • 1
    • 2
    • 3
  3. 将 SSH 密钥添加到 ssh-agent

    ssh-add ~/.ssh/id_ed25519
    
    • 1
2.3 将 SSH 公钥添加到 GitHub 上的帐户
  1. 将 SSH 公钥复制到剪贴板

    $ pbcopy < ~/.ssh/id_ed25519.pub
    
    • 1
  2. 在 GitHub 任何页面的右上角,点击头像,然后点击设置

    截屏2023-07-15 14.16.31
  3. 打开左侧的 SSH and GPG keys

    截屏2023-07-15 14.17.16
  4. New SSH key

    image-20230715141846805

    起个好听的名字,然后把第一步中复制的公钥粘贴进去
