一.环境1.1 操作系统（其他发行版亦可）：
[root@gysl ~]# cat /etc/centos-release
CentOS Linux release 7.5.1804 (Core)1.2 Git版本：
[root@gysl ~]# git --version
git version 1.8.3.12.1 下载并安装Git软件。
[root@gysl ~]# yum -y install git2.2 创建SSH key。
[root@gysl ~]# ssh-keygen -t rsa -b 2048 -C "gysl@github.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory ‘/root/.ssh‘.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:QYCyVkZQyuMZFG4vH8ulyo7L4x5Jz1ewWhhD69mVhI8 gysl@github.com
The key‘s randomart image is:
+---[RSA 2048]----+
| +*o.oo. |
| +o.=.... |
| BO .oo. |
| o+=*E+. . |
| o++o+..S |
|. ++o=. |
| o +=. |
|.+... |
|=*= |
+----[SHA256]-----+这里简单提一下ssh-keygen的几个选项，-t指定加密算法，-b指定位数，-C可以理解为注释（comment)，随意填写，可以填写为管理员邮箱。连续按几次enter键即可，其余不必理会。
2.3 在GitHub的settings里面添加刚刚创建的SSH key的公钥。
[root@gysl /]# cat ~/.ssh/id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDjI58Vk8kCQqu6PPng8/bjkZY2JrsH/kExR9JpZ9I+i71H744Mpi7VnaBnbgye15ri4jG7DKFVMUKU7dflplL4+th90B2QIAEBKrXbIUV9LJH5InL/uJQ9+Gu7NK/vIboFhFLKgSzE3EU3p5SQcCNkGFL9ygQ18FPE2d2mwm+fOhNC73OrlADqZwLJ99wXKoH+3wX/b0l+NBsCE7usPE4bxQK6ZDWtjjvsQ2QWtlGO4ia7m3VdDmumV2byFEyeEpAN2dbMmlkVeix8+VmVNkPbJKkeSyjIXaJcjDJdyeqCcV0Kwx9jY+yU13LVZIBJ4wUBvtjO/u/RKDDsz1Ie+QrJ gysl@github.com上一步连续按了几次回车键，其实就是采用默认设置，默认情况下新生成的key位于~/.ssh/目录下。把id_rsa.pub的内容添加到GitHub。具体步骤为：settings(点击右上角用户头像) -> SSH and GPG keys -> New SSH key -> ADD SSH key.Title随便填，Key部分就是复制的内容。也可以在登陆后直接输入以下地址：https://github.com/settings/ssh/new
2.4 测试一下是否添加成功。
[root@gysl /]# ssh -T git@github.com
The authenticity of host ‘github.com (52.74.223.119)‘ can‘t be established.
RSA key fingerprint is SHA256:nThbg6kXUpJWGl7E1IGOCspRomTxdCARLviKw6E5SY8.
RSA key fingerprint is MD5:16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘github.com,52.74.223.119‘ (RSA) to the list of known hosts.
Hi mrivandu! You‘ve successfully authenticated, but GitHub does not provide shell access.此处需要输入一个yes。出现以上内容，说明key已经添加成功。
2.5 Clone一个自己的仓库试一下。
[root@gysl /]# git clone git@github.com:mrivandu/MyImageHostingService
正克隆到 ‘MyImageHostingService‘...

Hi mrivandu! You‘ve successfully authenticated, but GitHub does not provide shell access.再次体会到成功的喜悦。以上内容是使用本人的GitHub账户亲自实战的，私钥已删除，请勿使用此私钥尝试连接本人GitHub仓库。
3.1 很久之前就在使用Github了，但是一直未能写一片关于GitHub的使用教程。GitHub为我们的coding工作带来了极大便利，学会使用这个工具显得格外重要。
3.2 本文仅仅介绍了Git在Linux环境下的主要配置方法，其他环境也大同小异。
3.3 文中涉及到的git命令的使用极为简单，如需进一步使用，还需要进行系统话的学习，此步骤可以参阅本文相关资料部分。
3.4 我的GitHub除了代码托管之外，还被我当成了博客备份的地方及图床，一般人我都不告诉他。此处邪恶一笑~
