之前在linux系统上登录GitHub都是用用户和密码登录的，现在打算用ssh登录GitHub，这样更安全，也不用输密码。
先配置git的用户名和邮箱：
git config --global user.name "your_name"
git config --global user.email "your_email@xxx.com"
先查看本地是否已经配置了公钥和私钥，如果已经存在私钥，无需再次生成。
cd ~/.ssh
生成密钥：
-> % ssh-keygen -t rsa -b 4096 -C your_email@xxx.com
Generating public/private rsa key pair.
Enter file in which to save the key (/home/ubuntu/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/ubuntu/.ssh/id_rsa.
Your public key has been saved in /home/ubuntu/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:14HZgHvg4z5qnFwlcrUeZ7AzxOpp+cka9oEMPrr04YQ xxx@gmail.com
The key's randomart image is:
+---[RSA 4096]----+
| o. |
| o == |
| . *o+o |
| . B O.o. |
| .=SO.*. |
| o oBo. |
| Eo===o.. |
| . ==+oo+. |
| oo+..o. |
+----[SHA256]-----+
生成密钥后拷贝公钥id_rsa.pub的内容，到GitHub上新建ssh的key：GitHub SSH and GPG keys
新建完成后就可以登录GitHub了：
-> % ssh -T git@github.com
The authenticity of host 'github.com (13.229.188.59)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'github.com,13.229.188.59' (RSA) to the list of known hosts.
Hi xxx! You've successfully authenticated, but GitHub does not provide shell access.
现在可以用ssh进行clone仓库的操作了：
-> % git clone git@github.com:xxx/xxx.github.io.git
