1. 为 Github 生成 SSH 密钥
ssh-keygen -t ed25519 -C "your_email@example.com" -f ~/.ssh/id_ed_github
将 id_ed_github.pub 添加到 Github SSH keys中。Settings -> Access ->SSH and GPG keys -> New SSH keys
参考：Gitehub 生成新的 SSH 密钥并将其添加到 ssh-agent
2. 为 Gitee 生成 SSH 密钥
ssh-keygen -t ed25519 -C "your_gitee_email@example.com" -f ~/.ssh/id_ed_gitee
将 id_ed_gitee.pub 添加到 Gitee SSH 公钥中。设置 -> 安全设置 -> SSH 公钥
参考：Gitee SSH 公钥设置
3. 配置 SSH 的 config 文件
# Github
Host github.comHostName github.comPort 22User gitPreferredAuthentications publickeyIdentityFile ~/.ssh/id_ed_githubIdentitiesOnly yes# Gitee
Host gitee.comHostName gitee.comPort 22User gitPreferredAuthentications publickeyIdentityFile ~/.ssh/id_ed_giteeIdentitiesOnly yes
