Vagrant + Drupal + Drush Automating setup of a Drupal development environment John Kary @johnkary Lawrence Coders May 2012 

Web Application Environments Your languages of choice and all their dependencies 

Development Environments 

Virtual Machines 

Virtual Machines • Abstracts host hardware • Install many guest operating systems • Goals • Mimic your staging/prod environments • Every team dev has the same environment • Isolate configuration between projects 

Vagrant Create and configure lightweight, reproducible, and portable development environments. 

Vagrant • Create VirtualBox VMs • Config file written in Ruby • Runs a “headless” VM • Can SSH to the it like a remote server 

No content

Vagrant + Chef Source code describing how each part of your infrastructure will be built, and appling those descriptions to individual servers. Configuration Automation 

Vagrant + Chef • Script install and configuration of dependencies • Recipes - https://github.com/opscode/cookbooks • Custom recipes versioned in git • Configure our VM • Install Apache, MySQL, PHP, PEAR, memcached • php.ini • MySQL accounts • /etc/profile

WDID Dev Environment •  • WDID VM • Ubuntu 11.04 w/ package updates • Mounts host’s /Users/username/Sites • Local Mac DNS magic forwards domains 

WDID Dev Environment http://kudrupal.local.dev /Users/johnkary/Sites/kudrupal_dev/public_html hosts... Never write a site definition again! 

WDID Dev Environment ~/Desktop/not-a-vagrant-dir $ vagrant up A Vagrant environment is required to run this command. Run `vagrant init` to set one up. ~/Desktop/not-a-vagrant-dir $ Must invoke vagrant where .vagrant dir lives 

WDID Dev Environment ~ $ cat ~/.bash_profile wdidvm () { eval 'cd ~/vagrant/wdid && vagrant' $*; cd $OLDPWD; } Or invoke Vagrant commands from anywhere! ~/Desktop/not-a-vagrant-dir $ wdidvm up [default] VM already created. Booting if it's not already running... [default] Resuming suspended VM... [default] Booting VM... [default] Waiting for VM to boot. This can take a few minutes.

WDID Dev Environment ~/Desktop/not-a-vagrant-dir $ wdidvm ssh Welcome to Ubuntu 11.04 (GNU/Linux 2.6.38-8-server x86_64) Last login: Thu May 17 20:17:34 2012 from 10.0.2.2 vagrant@natty:~$ pwd /home/vagrant vagrant@natty:~$ Must SSH to Vagrant VM to execute commands 

WDID Dev Environment ~ $ cat ~/.bash_profile wdidvmexec () { local wdidcode=`pwd`; eval 'ssh wdidvm -t "cd' $wdidcode'; '$*'"'; } Or invoke VM SSH commands from a mounted dir! ~/Sites/kudrupal_dev $ wdidvmexec whoami vagrant ~/Sites/kudrupal_dev $ wdidvmexec drush cc all 

WDID Drupal • WDID VM setup • Checkout our Drupal repo to Mac • ~ $ wdidvm up • Get some coffee • ~ $ wdidvmexec bin/installvm.drush.sh • Fully working Drupal install • All modules installed/config • Test users with role combinations • http://kudrupal.local.dev 

Drush Make • Automated downloading of Drupal core + modules ~/Sites/kudrupal_dev $ cat kudrupal.make core = 7.x api = 2 ; MODULES projects[admin_menu][version] = "3.x-dev" projects[admin_menu][subdir] = contrib projects[advanced_help][version] = "1.0" projects[advanced_help][subdir] = contrib projects[colortheme][version] = "1.0" projects[colortheme][subdir] = contrib 

Drush Make • Automated downloading of Drupal core + modules ~/Sites/kudrupal_dev $ drush make --no-core >> --contrib-destination=/profiles/kudrupal >> --prepare-install kudrupal.make -y -i .drush/ Project information for admin_menu retrieved. [ok] Project information for advanced_help retrieved. [ok] Project information for colortheme retrieved. [ok] admin_menu downloaded from http://ftp.drupal.org/files/projects/admin_menu-7.x-3.x-dev.tar.gz.

[ok] 

Drush site-install • Automated provisioning of Drupal • Faster than going through the UI ~/Sites/kudrupal_dev $ drush si kudrupal >> --db-url=mysql://myadmin:[email protected]/kudrupal >> --site-name=KU-Drupal [email protected] >> --account-name=user1 --account-pass=user1 -y
