一、安装git

sudo apt-get install git

二、设置git用户名与邮箱

根据GitHub仓库注册的用户名与邮箱进行设置:

git config --global user.name "Your Name"
git config --global user.email "email@example.com"
git config --global credential.helper store

查看设置结果:

$ git config -l
user.name=Your Name
user.email=email@example.com
credential.helper=store

三、生成SSH密钥

(1)查看是否已经有ssh密钥:

ls ~/.ssh

如果没有密钥则不会有此目录,有则备份删除!

(2)生成密钥:

输入命令后连续按下三次回车键!

$ ssh-keygen -t rsa -C "email@example.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/home/book/.ssh/id_rsa):
Created directory '/home/book/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/book/.ssh/id_rsa.
Your public key has been saved in /home/book/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx email@example.com
The key's randomart image is:
+---[RSA xxxx]----+
| N |
| e |
| u |
| t |
| i |
| o |
| n |
| wei |
| |
+----[SHA256]-----+

(3)查看公钥并复制:

$ cat /home/book/.ssh/id_rsa.pub
ssh-rsa xxxxxxxxxx email@example.com

四、 GitHub仓库添加SSH key

(1)登陆GitHub仓库:https://github.com/

(2)添加公钥:

a、进入“Settings”:

Linux配置篇 | Ubuntu配置git远程连接GitHub仓库_用户名

b、点击“SSH and GPG keys”: 

Linux配置篇 | Ubuntu配置git远程连接GitHub仓库_ssh_02

c、新建“SSH key” :

Linux配置篇 | Ubuntu配置git远程连接GitHub仓库_用户名_03

d、添加SSH公钥到“Key”下,“Title”随便命名,然后点击增添“SSH key”:

Linux配置篇 | Ubuntu配置git远程连接GitHub仓库_ssh_04
