First install etckeeper, it is simple on Debian Jessie:
# apt-get install etckeeper
Generate the key for git server:
root@milliondollarserver:~# ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: f2:20:f2:20:f2:20:f2:20:f2:20:f2:20:f2:20:f2:20 root@milliondollarserver The key's randomart image is: +---[RSA 2048]----+ | | | | | | | o | | oSo E | | +.... .. | | .....o .+=| | ..o +.**| | .o.=.B| +-----------------+
Setup Git:
root@milliondollarserver:~# git config --global user.email root@milliondollarserver.com root@milliondollarserver:~# git config --global user.name root@milliondollarserver root@milliondollarserver:~# cd /etc/ root@milliondollarserver:/etc# etckeeper init root@milliondollarserver:/etc# git commit -m "initial checkin" [master 7c33032] initial checkin 4 files changed, 14 insertions(+), 4 deletions(-) delete mode 100644 check_mk/mysql.cfg create mode 100644 python/debian_config create mode 100644 python2.7/sitecustomize.py
Hook it up with my Git server:
cd /etc git remote rm origin git remote add origin gitolite3@git.milliondollarserver.com:etckeeper-milliondollarserver
Add auto push:
cd /etc/etckeeper/commit.d (echo ‘#!/bin/sh’ ; echo ‘git push origin’) > 60git-push chmod +x 60git-push
Try to push:
cd /etc git add . git commit -m “automatically push commits to backup repository” /etc# git push
You will got warning:
warning: push.default is unset; its implicit value has changed in
Git 2.0 from 'matching' to 'simple'. To squelch this message
and maintain the traditional behavior, use:
git config --global push.default matching
To squelch this message and adopt the new behavior now, use:
git config --global push.default simple
When push.default is set to 'matching', git will push local branches
to the remote branches that already exist with the same name.
Since Git 2.0, Git defaults to the more conservative 'simple'
behavior, which only pushes the current branch to the corresponding
remote branch that 'git pull' uses to update the current branch.
See 'git help config' and search for 'push.default' for further information.
(the 'simple' mode was introduced in Git 1.7.11. Use the similar mode
'current' instead of 'simple' if you sometimes use older versions of Git)
fatal: The current branch master has no upstream branch.
To push the current branch and set the remote as upstream, use
git push --set-upstream origin master
Run these 2 command to push:
:/etc# git config --global push.default simple :/etc# git push --set-upstream origin master
You should have output like this:
