Adding your SSH key to the ssh-agent
Before adding a new SSH key to the ssh-agent to manage your keys, you should have checked for existing SSH keys and generated a new SSH key.
- Start the ssh-agent in the background.
$ eval "$(ssh-agent -s)"
> Agent pid 59566
- Add your SSH private key to the ssh-agent. If you created your key with a different name, or if you are adding an existing key that has a different name, replace id_rsa in the command with the name of your private key file.
$ ssh-add ~/.ssh/id_rsa
