Initial git & github configuration

ssh keys

Configure github ssh keys: https://help.github.com/articles/connecting-to-github-with-ssh/

gpg keys

• Generate gpg keys: https://help.github.com/articles/generating-a-new-gpg-key/

• Add gpg key to github: https://help.github.com/articles/adding-a-new-gpg-key-to-your-github-account/

• Tell to git which key to use https://help.github.com/articles/telling-git-about-your-gpg-key/

• Tell git to sign all commits:

  git config --global commit.gpgsign true
  

• Make gpg remember your passphrase

  # Update gpg-agent config
  # 28800 is 8 hours
  echo "default-cache-ttl 28800" >> ~/.gnupg/gpg-agent.conf
  echo "max-cache-ttl 28800" >> ~/.gnupg/gpg-agent.conf
  
  # tell git to use gpg-agent
  git config --global gpg.program gpg2
  
  # install gpg2 if needed
  sudo apt-get install gnupg2
  
  # restart gpg-agent
  gpgconf --kill gpg-agent
  gpg-agent --daemon
  

• Make a backup if needed

  # make backup file and move it to secret place
  gpg --export-secret-keys > secret-backup.gpg
  
  # you will be able to restore keys by following command:
  gpg --import secret-backup.gpg
  # or
  gpg2 --import secret-backup.gpg
  

警告

If you lost your key or forgot password, you need to create new one, but don’t remove old one from github, because otherwise all signed by old key commits will be “Unverified”

git email

• Configure email in git. Email must be the same as in github settings:

  git config --global user.email "your_email@example.com"
  

git editor

git config --global core.editor "nano"

gitignore

• Configure global gitignore

  Possible content for ~/.gitignore_global:

  *~
  *.pyc
