This works great on Rackspace Cloud Sites, and eliminates the need to upload an archive or individual files. Script works by grabbing and unpacking the latest stable version of WordPress.

  1. Create a new file in your web root, ie: deploy.php
  2. Add the contents from below
  3. Upload the file
  4. Visit http://yourdomain.com/deploy.php
  5. When the script is complete, connect via SFTP and edit wp-config.php accordingly
  6. The script will have unpacked WordPress and deleted itself
  7. Behold the glory that is WordPress, and the fuzzy feeling that accompanies going from zero to WordPress in but a minute.
