Deploy Drupal sites to remote server with GIT and Capistrano

Submitted by Sam Rose on Thu, 07/01/2010 - 06:25

Follow the instructions here for creating users on source server:

http://mattrude.com/2009/07/creating-a-secure-git-repository-server/

(ignore the rest of instructions on that blog post)

Capistrano set up will then be the same as http://socialsynergyweb.org/network/blog/building-capistrano-recipe-rail...

$my_string = "Login";
