如何正确配置涉及 github 和 bitbucket 的多个远程帐户的 ssh 密钥？

Question

我在本地和远程创建并配置了三个 ssh 密钥，如下所示：

SSH 密钥 - 电子邮件

$> cat ~/.ssh/id_rsa.pub (E-mail Bitbucket)
ssh-rsa AAAAB3.../kJVKej/5 ricardoramos.usp@gmail.com

$> cat ~/.ssh/id_rsa_git_hub.pub (E-mail Github1 is the same account Bitbucket)
ssh-rsa AAAAB3...Iq9FkLN6L ricardoramos.usp@gmail.com

$> cat ~/.ssh/id_rsa_back_track.pub (E-mail Github2)
ssh-rsa AAAAB3N...MSdYFaZ0d ricardo.comp.ufla@gmail.com

列出 SSH 密钥（同一电子邮件的两个不同 ssh 密钥）

$> ssh-add -l
2048 6b:0b:dd...e6:b7 ricardoramos.usp@gmail.com (RSA)
2048 fc:20:37...1a:ec ricardo.comp.ufla@gmail.com (RSA)
2048 45:4c:92...40:70 ricardoramos.usp@gmail.com (RSA)

配置 ~/.ssh/config 文件

#Default Bitbucket - User = ricardoramos
Host bitbucket.org
  HostName bitbucket.org
  User git
  IdentityFile ~/.ssh/id_rsa

#Account GitHub1 - User = ricardousp
Host github.com
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa_git_hub

#Account GitHub2 - User = ricardormoliveira
Host github.com
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa_back_track

此外，我还创建了一个名为 test 和远程配置的本地存储库：

$> git remote -v

origin  git@github.com:ricardormoliveira/testing.git (fetch)
origin  git@github.com:ricardormoliveira/testing.git (push)

但是，当我尝试使用我的 ricardormoliveira 远程用户推送时，会出现以下消息：

$> git push origin master
ERROR: Permission to ricardormoliveira/testing.git denied to ricardousp.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

我如何使用我的 ricardormoliveira 用户而不是 ricardousp 用户执行 git push？为什么 git 会改变我的用户？我做错了什么？

Answer 1

我的解决方案是：

我的帐户：

比特桶
Usuário: 里卡多拉莫斯
邮箱：ricardoramos.usp@gmail.com

Github – 01
Usuário: ricardousp
邮箱：ricardoramos@icmc.usp.br

Github – 02
Usuário: ricardormoliveira
邮箱：ricardo.comp.ufla@gmail.com

为每个帐户执行以下步骤：

1. ssh-keygen -t rsa -C "my email"
2. ssh-add ~/.ssh/(key name without the .pub)
3. key之后没有运行命令ssh-add -D，因为我 以为这个命令只会擦除 chache 而实际上这是 是我的错！
4. ssh-add -l
5. 进入目录~/.ssh
6. 如果没有配置文件，直接在目录下创建即可 ~/.ssh
7. sudo nano config
8. 在配置文件ssh文件夹中添加如下设置

我最终的 ssh 配置文件：

#Default Bitbucket email:ricardoramos.usp@gmail.com
Host bitbucket.org-ricardoramos
  HostName bitbucket.org
  User git
  IdentityFile ~/.ssh/id_rsa

#Account GitHub1 email:ricardoramos@icmc.usp.br
Host github.com-ricardousp
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa_github

#Account GitHub2 email:ricardo.comp.ufla@gmail.com
Host github.com-ricardormoliveira
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa_sec

完成创建和配置所有密钥后，只需设置远程存储库：

1. cat ~/.ssh/id_rsa.pub
2. 将我的密钥ssh-rsa AAAAB3Nz... my email复制到剪贴板
3. 在 bitbucket 或 github 中访问我的配置 > SSH 密钥添加 键

执行所有步骤后，推送正常！

你所做的一切都是正确的。

这里也有描述：Managing two ssh keys

看起来您没有将密钥添加到远程服务器。

---

为不同的 github 帐户设置多个 SSH Keys：

https://gist.github.com/jexchan/2351996

---

create different public key

根据文章 Mac Set-Up Git 创建不同的 ssh 密钥

$ ssh-keygen -t rsa -C "your_email@youremail.com"

例如，2 个密钥创建于：

~/.ssh/id_rsa_activehacker
~/.ssh/id_rsa_jexchan

Add these two keys to the ssh-agent:

$ ssh-add ~/.ssh/id_rsa_activehacker
$ ssh-add ~/.ssh/id_rsa_jexchan
you can delete all cached keys before

$ ssh-add -D

check your keys

$ ssh-add -l

Modify the ssh config

$ cd ~/.ssh/
$ touch config
$ subl -a config

Add the keys to the config file:***

#activehacker account
Host github.com-activehacker
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_activehacker

#jexchan account
Host github.com-jexchan
HostName github.com
User git
IdentityFile ~/.ssh/id_rsa_jexchan

Clone you repo and modify your Git config

# clone your repo 
git clone git@github.com:activehacker/gfs.git gfs_jexchan

cd gfs_jexchan and modify git config

$ git config user.name "jexchan"
$ git config user.email "jexchan@gmail.com" 

$ git config user.name "activehacker"
$ git config user.email "jexlab@gmail.com" 

# or you can have global 
git config $ git config --global user.name "jexchan" 
git config --global user.email "jexchan@gmail.com"

push your code

git add .
git commit -m "your comments"
git push
