Use these steps to clone live sites into dev enviroments, for example.

Tested for:
Ubuntu 14.04
Drupal 7
CiviCRM 4.7

• Create a snapshot of the droplet, and from that snapshot, create a new droplet

• disable outgoing emails, to prevent automated workflows from sending emails from this dev server.
  sudo nano /etc/postfix/main.cf
  add this line at the bottom of the file:
  default_transport = error:No outside emails.

• Create a copy and then edit the Drupal nginx config file to update server_name and set server to listen to port 80 instead 0f 443, and remove redirects (assuming the live site was set up to force SSL).
  ssh mysudoeruser@myipaddress
cd /etc/nginx/sites-enabled
scp drupal /home/mysudoeruser/drupal.txt
sudo nano drupal

• make sure the new nginx config file works properly by testing it
  sudo service nginx configtest

• Restart Nginx service
  sudo service nginx restart

• Edit settings.php to update the base_url variable with the IP address of the droplet you're setting up.
  sudo nano <drupal-root>/sites/default/settings.php

• Edit civicrm.settings.php to update the CIVICRM_UF_BASEURL variable with the new URL, like the to do above, but with an ending /.
  sudo nano <drupal-root>/sites/default/civicrm.settings.php

• Remove all files from the templates_c directory
  sudo rm -r <drupal-root>/sites/default/files/civicrm/templates_c/*

• Ensure this templates_c directory permissions allow for the application to add files to it.
  sudo chown -R www-data:www-data <drupal-root>/sites/default/files/civicrm/templates_c

• Remove the Config.IDS.ini file
  sudo rm <drupal-root>/sites/default/files/civicrm/ConfigAndLog/Config.IDS.ini

• Clear Drupal Cache
  cd <drupal-root>
sudo drush cc all

• Log into the site, /user, and disable CiviCRM's force SSL setting at civicrm/admin/setting/url?reset=1

• Disable CiviCRM's crob, to avoid scheduled reminders other automated tasks from running.
  sudo -u www-data crontab -e
