Remote Repo

Generate SSH private and public key​

Open Shell (open Git Bash in Windows) and create an SSH Key:

ssh-keygen -t rsa -C "youremail@example.com"

User's home directory .ssh, which contains id_rsa and id_rsa.pub files. These two are the SSH Key key pair.

  • id_rsa are private keys and cannot be leaked.
  • id_rsa.pub are public keys and can be told to anyone with confidence.
  • copy paste id_rsa.pub into youe Github acc

Git repository work with both HTTPS and SSH protocols​

Check your current remote URL with : git remote -v

  • If the URL starts with https://github.com, Git will prompt for your GitHub credentials instead of using SSH.

Change the remote URL to use SSH : git remote set-url origin git@github.com:username/repo.git

Verify SSH authentication works : ssh -T git@github.com

Why does GitHub need an SSH Key?​

Because GitHub needs to identify that the commits you push are indeed pushed by you, not someone else pretending to be you. Git supports the SSH protocol, so as long as GitHub knows your public key, it can confirm that only you can push.

1.Adding a remote repo​

git remote add origin git@github.com:michaelliao/learngit.git

git push -u origin master

Summary​

  • To associate a remote library, use the command git remote add origin git@server-name:path/repo-name.git;
  • When you associate a remote library, you must specify a name for the remote library, originwhich is the default customary naming;
  • After associating, use the command to push all the contents of the branch git push -u origin masterfor the first time ;master
  • After that, after each local commit, you can use the command to push the latest changes whenever necessary git push origin master;
  • One of the biggest benefits of a distributed version control system is that you don't need to consider the existence of a remote repository when working locally, that is, it can work normally whether you have an Internet connection or not, while SVN refuses to work when there is no Internet connection! When there is a network, you can push the local commits to complete the synchronization, which is really convenient!

2. Cloning from a remote repo​

git clone <https>
