Run Composer Binaries From Project Directories

As a PHP developer I often find myself having to run executable files installed to a project via Composer (e.g. php-cs-fixer, phpunit, psysh, etc.). These binary files typically reside in vendor/bin relative to the root of a project and in order to run these binary files from the project root I would need to cd into the vendor/bin directory first or type out the relative path (e.g. vendor/bin/php-cs-fixer fix) every time I wanted to run one of these executables.

However, my home server lies behind my ISP and they block all outbound emails citing SPAM as the reason. Regardless of their reasoning I had to find a workaround to allow me to send email notifications from behind my ISP. Well, it turns out this is rather painless with postfix and a Gmail account.

Having set up several Debian and Ubuntu web servers in the past I thought it would be a good idea to share my process. The following is a relatively comprehensive guide to installing and configuring an Apache based web server with some optimizations and basic resource monitoring. I primarily work with Ubuntu servers, but most of the commands here should work exactly the same in Debian or Ubuntu. I've tried to note where differences may occur.
