管理多个 ssh-key 多个 github 账号

1: create different public key

create different ssh key according the article Mac Set-Up Git


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

Please refer to github ssh issues for common problems.

for example, 2 keys created at:


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

then, add these two keys as following


$ ssh-add ~/.ssh/id_rsa_activehacker
$ ssh-add ~/.ssh/id_rsa_jexchan

you can delete all cached keys before


$ ssh-add -D

finally, you can check your saved keys


$ ssh-add -l

2: Modify the ssh config


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

Then added


#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

3: 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”

then use normal flow to push your code


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