git生成gitee和github两个不同的公钥

news 2025/7/5 0:43:00

配置多个公钥

Windows 用户建议使用 Windows PowerShell 或者 Git Bash，在 命令提示符 下无 cat 和 ls 命令。

1、生成公钥文件：

通过命令 ssh-keygen 生成 SSH Key：

ssh-keygen -t rsa -C "Gitee SSH Key" -f ~/.ssh/gitee_bealei_rsassh-keygen -t rsa -C "Github SSH Key" -f ~/.ssh/github_bealei_rsa

-t key 类型
-C 注释
-f 指定用来保存密钥的文件名

输出，如：

Bealei@Y7000 MINGW64 /d/Desktop
$ ssh-keygen -t rsa -C "Gitee SSH Key" -f ~/.ssh/gitee_bealei_rsa
Generating public/private rsa key pair.
/c/Users/Administrator/.ssh/gitee_bealei_rsa already exists.
Overwrite (y/n)?Bealei@Y7000 MINGW64 /d/Desktop
$ ssh-keygen -t rsa -C "Gitee SSH Key" -f ~/.ssh/gitee_bealei_rsa
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Administrator/.ssh/gitee_bealei_rsa
Your public key has been saved in /c/Users/Administrator/.ssh/gitee_bealei_rsa.pub
The key fingerprint is:
SHA256:zTjk4lQJkyjatPJa8fucucXVkBPtV4o2LWj3CkcLfW4 Gitee SSH Key
The key's randomart image is:
+---[RSA 3072]----+
|     .o.  ..     |
|  o . .o . o.   .|
| + o    + ++ o o |
|o +    + +++X =  |
| o o  o S.+=.O   |
|  o .o o o. o E  |
| o   .. o  o o   |
|.   .. +    .    |
|     .*.         |
+----[SHA256]-----+

Bealei@Y7000 MINGW64 /d/Desktop
$ ssh-keygen -t rsa -C "Github SSH Key" -f ~/.ssh/github_bealei_rsa
Generating public/private rsa key pair.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Administrator/.ssh/github_bealei_rsa
Your public key has been saved in /c/Users/Administrator/.ssh/github_bealei_rsa.pub
The key fingerprint is:
SHA256:LveFZoIaZF5OdMHtNf5hb7VaH+2dhqPXiOxuIFT2QJw Github SSH Key
The key's randomart image is:
+---[RSA 3072]----+
|       .+o.      |
|        .E. o    |
|      . +.oo .   |
|     . o  ... o .|
|    o + S    o o+|
|   + + + . .  .++|
|    o + = * o *o=|
|     o o = = * ++|
|    .     =+o o  |
+----[SHA256]-----+

生成如下文件，其中gitee_bealei_rsa.pub为公钥，gitee_bealei_rsa为私钥：

在这里插入图片描述

2、读取公钥文件：

cat ~/.ssh/gitee_bealei_rsa.pub

输出，如：

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAAB********************Zm8= Gitee SSH Key

复制终端输出的公钥。

cat ~/.ssh/github_bealei_rsa.pub

输出，如：

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAAB********************Igs= Github SSH Key

复制终端输出的公钥。

3、配置仓库公钥

将生成的公钥，配置到gitee及github各自账户下

4、配置config文件

在.ssh目录下新建config.txt文件，编辑配置内容如下，去掉后缀保存文件名为config

# gitee
Host gitee.com
HostName gitee.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/gitee_bealei_rsa# github
Host github.com
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/github_bealei_rsa

5、测试连接

在本地git 的命令行中测试连接两种仓库，连接成功

# gitee
ssh -T git@gitee.com# github
ssh -T git@github.com

输出：

# gitee
Bealei@Y7000 MINGW64 /d/Desktop
$ ssh -T git@gitee.com
Hi bealei(@bealei)! You've successfully authenticated, but GITEE.COM does not provide shell access.# github
Bealei@Y7000 MINGW64 /d/Desktop
$ ssh -T git@github.com
Hi bealei! You've successfully authenticated, but GitHub does not provide shell access.
