A Brief Introduction to Fabric

Fabric is a deployment management framework written in Python which makes remotely managing multiple servers incredibly easy. If you've ever had to issue a change to a group servers, this should look pretty familiar:

for s in $(cat servers.txt); do ssh $s service httpd graceful; done

Fabric improves on this process by providing a suite of functions to run commands on the servers, as well as a number of other features which just aren't possible in a simple for loop. While a working knowledge of Python is helpful when using Fabric, it certainly isn't necessary. This tutorial will cover the steps necessary to get started with the framework and introduce how it can be used to improve on administering groups of servers.

1. Clone your fork:

git clone [email protected]:YOUR-USERNAME/YOUR-FORKED-REPO.git

2. Add remote from original repository in your forked repository:

cd into/cloned/fork-repo
git remote add upstream git://github.com/ORIGINAL-DEV-USERNAME/REPO-YOU-FORKED-FROM.git
git fetch upstream

	sudo apt-get install build-essential libsqlite3-dev zlib1g-dev libncurses5-dev libgdbm-dev libbz2-dev libreadline5-dev libssl-dev libdb-dev

	wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz
	tar -xzf Python-2.7.3.tgz
	cd Python-2.7.3

	./configure --prefix=/usr --enable-shared
	make
	sudo make install
	cd ..

	<VirtualHost *:80>
	ServerAdmin {USER}@cslavoie.com
	ServerName {DOMAIN}
	ServerAlias www.{DOMAIN}
	ServerAlias {USER}.localhost
	ServerAlias {USER}.static.cslavoie.com

	DocumentRoot {DOC_ROOT}

	<Directory {DOC_ROOT}>
