How to manage multiple GitHub accounts on one machine

scene

On a computer, there are two repositories that belong to two different GitHub accounts.

step

Configure GitHub’s git account for repository

Use the terminal to enter the repository a directory and configure the GIT account

$ git config user.name "user_a"
$ git config user.email "[email protected]"

Use the terminal to enter the repository B directory and configure the GIT account

$ git config user.name "user_b"
$ git config user.email "[email protected]"

Generating SSH keys for different GitHub users

For user_ A generates an SSH key named user_ A_ Id_ RSA

$ ssh-keygen -t rsa -C "[email protected]"

The same operation, for user_ B generates an SSH key named user_ B_ Id_ RSA

$ ssh-keygen -t rsa -C "[email protected]"

Configure SSH matching of multiple accounts

In the. SSH directory, create a new config file and configure the key of multi-user

host user_a_github.com
    Hostname github.com 
    User git 
    IdentityFile ~/.ssh/user_a_id_rsa  

host user_b_github.com
    Hostname github.com 
    User git 
    IdentityFile ~/.ssh/user_b_id_rsa

Add a new private key to the SSH agent cache

$ eval "$(ssh-agent -s)"
$ ssh-add ~/.ssh/user_a_id_rsa
$ ssh-add ~/.ssh/user_b_id_rsa

Modify the push address of the repository

For the URL field value of. Git / config in the repository[email protected]Modification.

Modify the push address of repository a:

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
    ignorecase = true
    precomposeunicode = true
[remote "origin"]
    url = [email protected]_a_github.com:*********/***********.git
    fetch = +refs/heads/*:refs/remotes/origin/*
[user]
    name = user_a
    email = [email protected]

Modify the push address of repository a:

[core]
    repositoryformatversion = 0
    filemode = true
    bare = false
    logallrefupdates = true
    ignorecase = true
    precomposeunicode = true
[remote "origin"]
    url = [email protected]_b_github.com.com:******/******.git
    fetch = +refs/heads/*:refs/remotes/origin/*
[user]
    name = user_b
    email = [email protected]

That’s it.

Some orders

#Check current user
ssh -vT [email protected]
#Check the original key
ssh-add -l
#Add key
#Delete key
ssh-add -d /Users/****/.ssh/id_rsa
#View git config configuration
git config --list
