Setting up local git mirror

This tutorial explains how to save bandwidth when several local computers need to pull updates from a single remote git repository.

Use case

This tutorial will be about hosting a local mirror of funtoo git based portage tree.

Following terms should be adapted

Terms	Definition
git.lan	The git-daemon local mirror host
localhost	Any local host
nobody	Owner user of .git files
/home/git-mirrors	Base path of git-daemon

Local mirror

Git-daemon configuration

Prepare directories and clone portage-mini from github::

    root@git.lan # mkdir /home/git-mirrors
    root@git.lan # chown nobody /home/git-mirrors
    root@git.lan # su -s /bin/sh nobody
    nobody $ cd /home/git-mirrors
    nobody $ git clone --mirror --bare git://github.com/funtoo/portage-mini-2011.git portage.git

Configure git-daemon in /etc/conf.d/git-daemon::

    GITDAEMON_OPTS="--syslog --verbose --enable=receive-pack --export-all"
    GITDAEMON_OPTS="${GITDAEMON_OPTS} --base-path=/home/git-mirrors /home/git-mirrors"
    GIT_USER="nobody"
    GIT_GROUP="nobody"

Start Daemon::

    root@git.lan # /etc/init.d/git-daemon start
    root@git.lan # rc-update add git-daemon default

Pull from remote

Add to /etc/cron.daily/funtoo-sync.sh::

    #!/bin/sh

    cd /home/git-mirrors/portage.git
    su nobody -s "/bin/sh" -c "git fetch --all"

Cloning from local git-daemon

Local clone from git.lan::

    root@localhost # mv /usr/portage /usr/portage.old
    root@localhost # git clone git://git.lan/portage.git /usr/portage
    root@localhost # cd /usr/portage
    root@localhost # git checkout funtoo.org
