Multiple SSH Keys settings for different git account

This instruction helps create multiple ssh keys for local machine to use multiple git remote repositories.

Step 1: Create different ssh keys

$ ssh-keygen -t rsa -C "your_email1@youremail.com"
$ ssh-keygen -t rsa -C "your_email2@youremail.com"

Step 2: Create file config at ~/.ssh

Host bitbucket.org
    HostName bitbucket.org
    User git
    IdentityFile ~/.ssh/user1

Host git.everymatrix.com
    HostName git.everymatrix.com
    User git
    IdentityFile ~/.ssh/id_rsa

Step 3: Clone your repo and modify your Git config (Can skip this step if Host == HostName)

Checkout .git/config: Update Host in origin to the Host that defined in ~/.ssh/config

[remote "origin"]
    url = git@bitbucket.org:activehacker/gfs.git
    ...

Make sure @bitbucket.org to match config host
