Now that you've read the preface and know what you're getting yourself into, It is time to get your system ready to install NGINX and PHP-FPM.

You can get the source from NGINX and/or add the NGINX repositories to your system. There is a Debian specific Repository that you could use, there are also other distro-specific repositories that you could use, if your system happens to not be a Debian Server. You can find more information on these repositories here: NGINX Repositories

While the fore-mentioned REPO is perfectly valid, I choose to use the Debian Backports as my repository for NGINX. I chose this because this allowed for an easy configuration, and allowed me to install a more up-to-date version of NGINX on my system while giving me a more supported application for my environment. To add the Debian Backports to your repositories simply execute this echo command:

echo 'deb http://backports.debian.org/debian-backports squeeze-backports main' >> /etc/apt/sources.list.d/backports.list

After this has been added to your Source Repositories you will then need to add the DotDeb Repositories to your system so that you can install PHP-FPM.

To install the DotDeb Repositories into your system here is a crazy little command set:

echo 'deb http://packages.dotdeb.org stable all' >> /etc/apt/sources.list.d/DotDeb.list
echo 'deb-src http://packages.dotdeb.org stable all' >> /etc/apt/sources.list.d/DotDeb.list
wget http://www.dotdeb.org/dotdeb.gpg
cat dotdeb.gpg | sudo apt-key add -
rm dotdeb.gpg

This set adds the DotDeb Repositories to your sources, it then adds the GPG key to your system, and finally it removes the GPG key file from your system; so there are no leftovers from the installation.

After you have added the repositories to your system, update your sources with this simple command:

apt-get update
