github ssh多帐号支持

在使用github的时候有没有遇到管理多个帐号多个项目？每个github项目都有自己的ssh密钥、那怎么处理这种情况咧？来、跟着大猪一起来操作吧。

使用教程

帐号1：abc1
帐号2：abc2

1. 为帐号1生成rsa

ssh-keygen -t rsa -C "abc1"
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/dounine/.ssh/id_rsa): /Users/dounine/.ssh/abc1_rsa
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /Users/dounine/.ssh/abc1_rsa.
Your public key has been saved in /Users/dounine/.ssh/abc1_rsa.pub.
The key fingerprint is:
SHA256:1Xuzh9kmLFoFOseAc57wU/uxA8HdtZstqZHoVHDBL98 abc1
The key's randomart image is:
+---[RSA 2048]----+
|          ..o.  .|
|         . =.. .o|
|        + + B....|
|         B O.*..+|
|        S X OoB+.|
|         o + O.XE|
|          . + X +|
|           o . = |
|          .      |
+----[SHA256]-----+

2. 为帐号2生成rsa

ssh-keygen -t rsa -C "abc2"
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/dounine/.ssh/id_rsa): /Users/dounine/.ssh/abc2_rsa
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /Users/dounine/.ssh/abc2_rsa.
Your public key has been saved in /Users/dounine/.ssh/abc2_rsa.pub.
The key fingerprint is:
SHA256:1Xuzh9kmLFoFOseAc57wU/uxA8HdtZstqZHoVHDBL98 abc1
The key's randomart image is:
+---[RSA 2048]----+
|          ..o.  .|
|         . =.. .o|
|        + + B....|
|         B O.*..+|
|        S X OoB+.|
|         o + O.XE|
|          . + X +|
|           o . = |
|          .      |
+----[SHA256]-----+

3. 为两个帐号各添加ssh公钥

4. 复制 ~/.ssh/abc1_rsa.pub 与 ~/.ssh/abc2_rsa.pub 到对应的帐号即可。

5. config 配置

Host abc1.com
    HostName github.com 
    IdentityFile ~/.ssh/abc1_rsa
Host abc2.com
    HostName github.com 
    IdentityFile ~/.ssh/abc2_rsa

6. git项目配置 cat .git/config

abc1 帐号

[remote "origin"]
    url = [email protected]:abc1/test-project

abc2 帐号

[remote "origin"]
    url = [email protected]:abc2/test-project

提交就可以使用

git push
