When creating a new repository the following steps are required:

  • Create repo with

    $ sudo su -
    # cd /data/git
    # mkdir $repo.git
    # cd $repo.git
    # git init --bare
    # touch export
    # touch git-daemon-export-ok
    # cd ..
    # chown -R gitmirror.gitmirror $repo.git
    # chmod -R g+w $repo.git
    # find -type d $repo.git | xargs chmod g+s
  • Set the description and config files following other repos' example

  • Setup mirroring

    $ sudo su - gitmirror
    # ./newrepo.sh /data/git/$repo.git
    # cd mirrors
    # $HOME/sync-one.sh $repo.git
