同一台电脑免密访问多个Github帐号方法

一、为不同的帐号Github创建不同的公钥

同一台电脑，不同的Github帐号，不可以使用相同的公钥访问

C:\Users\admin>ssh-keygen -t rsa -C 123@qq.com
Generating public/private rsa key pair.
Enter file in which to save the key (C:\Users\admin/.ssh/id_rsa): C:\Users\admin/.ssh/id_rsa_hexohub
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in C:\Users\admin/.ssh/id_rsa_hexohub
Your public key has been saved in C:\Users\admin/.ssh/id_rsa_hexohub.pub
The key fingerprint is:
SHA256:eh90qjsF+gjHp2iu9U2k7eJ+WMJpGI0Veewx4aNuQnA 123@qq.com
The key's randomart image is:
+---[RSA 3072]----+
|      .+..       |
|      o.=        |
|  . E+ ooo       |
|   oo ..o.       |
|    .=.oS.. .    |
|   .o.O=o..o     |
|    o==O+.o      |
|   .o+==+o .     |
|  .+.o+o=o.      |
+----[SHA256]-----+


C:\Users\admin>ssh-keygen -t rsa -C 456@qq.com
Generating public/private rsa key pair.
Enter file in which to save the key (C:\Users\admin/.ssh/id_rsa): C:\Users\admin/.ssh/id_rsa_soxo
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in C:\Users\admin/.ssh/id_rsa_soxo
Your public key has been saved in C:\Users\admin/.ssh/id_rsa_soxo.pub
The key fingerprint is:
SHA256:mUOEBJAzt/Nz7g1SCqJe6KamGvpvQkX6yoVBoY46yyw 456@qq.com
The key's randomart image is:
+---[RSA 3072]----+
|  o+.o...        |
| .= o ..         |
|.. * .  .        |
|o o +  . o       |
|...=.o  S        |
|..+.o.oo..       |
|=+ +  o+.        |
|E*= .  ..o       |
|&*.+.  .. .      |
+----[SHA256]-----+



加上-f参数一次性创建:
ssh-keygen -t rsa -C "123@qq.com" -f ~/.ssh/id_rsa_hexohub
ssh-keygen -t rsa -C "456@qq.com" -f ~/.ssh/id_rsa_soxo
会生成id_rsa_hexohub.pub和id_rsa_soxo.pub这两个文件

二、查看公钥

C:\Users\admin>cd .ssh

C:\Users\admin\.ssh>dir
 Volume in drive C has no label.
 Volume Serial Number is 70E6-2E1B

 Directory of C:\Users\admin\.ssh

2024-07-03  15:48    <DIR>          .
2024-07-03  05:51    <DIR>          ..
2024-07-03  15:48             2,590 id_rsa_hexohub
2024-07-03  15:48               565 id_rsa_hexohub.pub
2024-07-03  15:47             2,590 id_rsa_soxo
2024-07-03  15:47               565 id_rsa_soxo.pub
2024-07-03  06:10               831 known_hosts
2024-07-03  06:10                93 known_hosts.old
               8 File(s)         10,404 bytes
               2 Dir(s)   1,331,605,504 bytes free
               

三、本地创建config配置文件

C:\Users\admin\.ssh\config   # 修改config文件，如果没有则创建config文件，添加如下内容
 
Host soxo.github.com
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_soxo
 
Host hexohub.github.com
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_hexohub

四、远程Github添加Key

将id_rsa_hexohub.pub和id_rsa_soxo.pub中的内容分别添加至各自的帐号中:
登录github，点击头像—设置—SSH and GPG keys—New SSH key—粘贴—Add SSH key

五、测试连接

C:\Users\admin>ssh -T git@soxo.github.com
Hi soxo! You've successfully authenticated, but GitHub does not provide shell access.

C:\Users\admin>ssh -T git@hexohub.github.com
Hi hexohub! You've successfully authenticated, but GitHub does not provide shell access.

六、hexo配置文件_config.yml添加deploy部署参数

deploy:

  - type: git
    repo: git@hexohub.github.com:hexohub/hexohub.github.io.git    
    branch: main
    
  - type: git
    repo: git@soxo.github.com:soxo/soxo.github.io.git  
    branch: gh-pages
    

七、上传代码

C:\Users\admin\hexo>hexo clean && hexo g && hexo d
