Join Jon Peck for an in-depth discussion in this video Automatically storing server config with etckeeper, part of Learning Linux for PHP Developers (2014).
…Code isn't the only thing that's useful…to store and revision control systems like Git.…Server configuration is critical to success, given its…impact on the ability for a server to function.…In a lot of ways it's like procedural code.…Being able to track changes over time and having a back up can be a real time saver.…Why not treat configuration like any other program?…Enter etckeeper, a collection of tools that can…store configuration in revision control repositories, including git.…Once we set it up, etckeeper will…automatically save changes to configuration in etc…after apt-get runs, checking for and saving…changes once a day, and manually as well.…
Let's set up etckeeper now.…From a terminal, we can use apt-get to install etckeeper.…So, sudo apt-get -y install etckeeper.…By default, the version control system used for etckeeper…is set to Bazaar, which is Canonical's version control system.…Let's switch it over to Git.…The configuration is in etc.…So we'll use, sudoedit /etc/etckeeper/etckeeper.com.…
We'll uncomment git, and comment out Bazaar.…
