Command line Drupal install and update script for multi-site hosting

Maintaining a Drupal site, or a collection of sites is much easier if everything is kept completely separate--Drupal core, contributed modules, and the site itself.
This is even more important if multiple sites are hosted on the same server. Drupal's own multi-site support can be a nightmare to maintain, believe me! (e.g. when you want to upgrade modules or core).
A must simpler and easily supported configuration is to keep everything separate and to use symbolic links to tie it all together. For example, I keep:

Webform formatting

As I wrote here:www.drupal.org/…omment-9134347

Webform descriptions can be made to take any tags using:

php -r "print json_encode(array('a', 'em', 'strong', 'code', 'img', 'ul', 'ol', 'li'));"  | drush vset --format=json webform_allowed_tags -
  • The first command generates:
["a","em","strong","code","img","ul","ol","li"]
  • which can be written to the variable and checked with:
drush vset --format=json webform_allowed_tags '["a","em","strong","code","img","ul","ol","li"]'
drush vget webform_allowed_tags  # check value is set

Clouidflare

So far CloudFlare has proved to be an excellent service. It is very useful for providing extra safety for old Drupal 5 sites that have not yet been upgraded.

JavaScript MVC Frameworks

A new way of creating a website is using what is sometimes called a “headless” site, with the front end being served by an MVC framework (Model View Controller).

Headless Drupal means using Drupal purely for content creation and management and feeding all the data in JSON format to a JavaScript front end.

Installing Open Atrium

Stragegy

  • download no-core version
  • replace all modules in repo with symbolic links
  • create standard Drupal 7 site
  • link openatrium directory into profiles/openatrium
  • install site using openatrium install profile
dget install openatrium 7.x-2.19-no-core d7paths
grep memory_limit /etc/php.ini       #should be >= 256M
grep max_allowed_packet /etc/my.cnf  #should be >= 32M (add under [mysqld]}
  • Go through OA contrib modules and any we have already replace with the one in the repo
mod=/opt/dr7/contrib/modules
oa=$mod/openatrium

function repoa {
  rm -Rf $oa/modules
