第一次通过 SSH key 免密连接 GitHub 的完整过程


通过密码连接GitHub总是要输入密码,麻烦,现在使用 SSH key 可以轻松实现免密验证.

创建 SSH key

使用 ssh-keygen 命令

ssh-keygen -t ed25519 -C "[email protected]" 

注意:将[email protected]换成自己的邮箱。

Generating public/private ed25519 key pair.
Enter file in which to save the key (/Users/mleo/.ssh/id_ed25519): 
Created directory '/Users/mleo/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 


Your identification has been saved in /Users/mleo/.ssh/id_ed25519
Your public key has been saved in /Users/mleo/.ssh/

配置 SSH key

touch ~/.ssh/config
Host                           # 别名
	Hostname                # GitHub 主机地址
	Port 		22                        # GitHub 主机端口
	User 		git                       # GitHub 主机用户
	Identityfile ~/.ssh/id_ed25519        # ssh-key
