git: 配置github的公钥

一，生成公钥

未生成：

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

已生成:

cat ~/.ssh/id_rsa.pub

二，在github上添加公钥

 Settings → SSH and GPG keys → New SSH key,

如图:

测试连接到git服务器:

$ ssh -T git@github.com
Hi liuhongdi! You've successfully authenticated, but GitHub does not provide shell access.

三，使用url:

选择ssh的地址

$ git remote set-url origin git@github.com:username/repository.git
