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

Prepare directories and get portage tree

# mkdir /home/git-mirrors
# chown nobody /home/git-mirrors
# su -s /bin/sh nobody
$ cd /home/git-mirrors
$ git clone --mirror --bare git://github.com/funtoo/ports-2012.git portage.git

For a security reason we use a nobody user .

git-daemon configuration

/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 --interpolated-path=/home/git-mirrors"
GIT_USER=nobody
GIT_GROUP=nobody

Service configuration

To start daemon with a mirror machine boot add git-daemon to default runlevel

# rc-update add git-daemon default

To make changes start immediately just run rc

# rc

Pull from remote

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

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

Cloning from local git-daemon

Local clone from git.lan:

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

Downstream Clients Settings

machines previously syncing to upstream mirrors need their portage moved:

# mv /usr/portage /usr/portage.old
/etc/portage/make.conf: define client sync source for emerge --sync
SYNC="git://git.lan/portage.git"
