LinuxDeploy CentOS7 设置Git通过SSH连接Github

前言

先安装好Git，并且配置好邮箱和用户名

1

3
4
[root@localhost .ssh]# git config --list
user.name=xxx
user.email=xxx@yyy.com
[root@localhost .ssh]#

生成秘钥

输入下面的命令,然后一直按回车键：

1
ssh-keygen -t rsa -C "你的邮箱"

运行效果：

[root@localhost ~]# ssh-keygen -t rsa -C "xxxxxxx@yyy.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:...... xxx@yyy.com
The key's randomart image is:
......

查看公钥

进入上面命令生成秘钥的路径(Your public key has been saved in /root/.ssh/id_rsa.pub.)：

1
cd /root/.ssh

[root@localhost .ssh]# ls
id_rsa  id_rsa.pub
[root@localhost .ssh]# cat id_rsa.pub 
ssh-rsa AAAAopuytC1yc2EAAAjkngfBAAABAQC4ABJjwlORTcIjU0mmCjGOSRYiF8MaKbQZLeF8Md46tgD2LhTLjOnlp09mcha/0uK8TpbWOO3Oq7u+5ageggsvcss3JItrKPEQn0OsXxDW9j7Du9PRAfyagagetvdbkIpxvxYmQ3flXdIG5YtZJHSuqmrKGOo+cZgj1PL4t2vnS2xKmbirdV5qndh3whadfgwertvgDAd57zFXzgWFxH09fI0Nq1oNQpk+MSDnIFyFNDO72VEQA/SYsk+92z056dEKvF1gHS92356478gfsM/JSPqmyJ+qwerfgtvdbd7JLLg6hzQ2LUjA0SGAsusBzHtM0SuxCoRTkdAd3vwwn9l xxx@yyy.com
[root@localhost .ssh]#

进入github网站 填写公钥

打开浏览器，登录github网站,然后点击右上角的头像的后面的三角按钮，选择Settings，然后点击SSH and GPG keys，点击SSH keys横栏右侧的New SSH key按钮。输入各个公钥的名称,我这里为CentoSOnLinuxDeploy。然后输入公钥，点击Add SSH key按钮。此时可能会要求输入密码，按提示输入密码即可。

测试是否能够连接

回到Xshell,输入如下命令测试连接，然后输入yes回车。

1
ssh -T git@github.com

ssh连接成功效果：

[root@localhost .ssh]# ssh -T git@github.com
The authenticity of host 'github.com (52.74.223.119)' can't be established.
RSA key fingerprint is SHA256:nThbg6kXUpJjskgjghJhshsuiwoJkARLviKwJuhnb8.
RSA key fingerprint is MD5:23:45:rt:2g:56:31:7u:89:sd:3h:56::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 xxx! You've successfully authenticated, but GitHub does not provide shell access.
[root@localhost .ssh]#

这样就可以使用github的SSH连接了，省去输入密码的麻烦。
