On the SitePoint.com site's "Web" category they're posted a tutorial showing off an interesting piece of software that helps make automated installs of CMS/frameworks easy: a simple bash script tool called Please.

If you’re a web developer, possibly one of your most boring and repetitive tasks is the configuration of the basic setup for every new project. Configuring your my-project.dev domain, creating the database, installing WordPress (or any other CMS/Framework) for the thousandth time: you already know how to do it. What if you could automate all of that?

Well, actually, you can. Please is a simple bash script that helps to automate the installations of many CMSs and Frameworks by configuring them automatically into your Vagrant box, adding a development domain name into your host file, and even a database if needed.

They start off by helping you get a Vagrant box up and running to use for the Please handling. You then clone the Please repository locally and can use the command line tool to set up the process for multiple CMS/framework types including WordPress, Laravel and React. There's also a section covering the creation of your own environment if you need something more custom. Please is currently in beta at the time of this post so be aware that there may still be issues that need resolving before it becomes stable.
