Drupal Installation

Drupal is a Content Management System (CMS) allowing to build a web portal with a friendly administration interface and with extensible capabilities. What is referred to Mica Drupal Client in this documentation consists of a set of Drupal modules and theme. These modules/theme will get the published data from the Mica server (through its web services) and will deliver them as Drupal pages. Drupal supports user authentication which is itself extended to use Agate user directory. This way Drupal users can authenticate on Agate and get the Mica pages adapted to their permissions.

This guide describes how to set up a Drupal server with Mica client modules/theme configured. It is intended for the the system administrators.


Server Hardware Requirements

Component Requirement
CPU Recent server-grade or high-end consumer-grade processor
Disk space 2GB or more.
Memory (RAM) Minimum: 4GB, Recommended: >4GB

Server Software Requirements

Software Suggested version Usage
Drupal 7.x Drupal application that will host Mica Client modules/theme.
Drupal requirements (PHP, database etc.) PHP >=5.5 See Drupal Requirements


System dependencies

For Linux systems the following dependencies need to be installed:

  • Debian
apt-get update
apt-get install mariadb-server php5.6 php5.6-mysql php5.6-curl php5.6-gd php5.6-cli php5.6-xml
  • CentOS
yum clean all
yum install mariadb-server php56w php56w-mysql php56w-gd php56w-cli php56w-xml

Drush and Composer

It is recommended to install Drush 7 (Drupal Shell) using Composer (Dependency Manager for PHP). See Drush install documentation.

Install Composer:

# Install Composer at system level (root access required)
curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

Install Drush via Composer tool:

# Install Drush and add composer installation directory to your execution path
composer global require drush/drush:7.*
echo "export PATH=\$HOME/.composer/vendor/bin:\$PATH" | tee -a $HOME/.bashrc
# For CentOS 7 you have to use :
echo "export PATH=\$HOME/.config/composer/vendor/bin:\$PATH" | tee -a $HOME/.bashrc
source .bashrc

# Verify Drush install
drush status

# Install composer module for Drush (allows Drush to use Composer)
drush dl composer-8.x-1.x

Drupal Server

Now you can install Drupal 7. The installation with Drush is recommended. See Drupal Documentation for details (we recommend you the installation with drush).


CentOS If you have problems about authorization (like httpd code 403 from apache), this error could be related to SELinux. You can disable SELinux (command : setenforce 0) to check if this resolves your problem (temporarily). See SELinux documentation for details.


The following modules and theme are required to have a fully functional Mica Drupal Client:

Name Type Drupal Link Usage
obiba_mica modules https://www.drupal.org/project/obiba_mica Uses Mica web services to render published content, data summaries and manage data access requests.
obiba_agate module https://www.drupal.org/project/obiba_agate Uses Agate web services to authenticate Mica users.
obiba_bootstrap theme https://www.drupal.org/project/obiba_bootstrap Bootstrap based Drupal theme with appropriate style sheets and page templates. Extension of bootstrap theme.

Once Drupal is installed on your system, run the following commands:

# Go to Drupal installation directory

# Download and enable Obiba bootstrap theme
drush en -y bootstrap
drush en -y obiba_bootstrap

# Download and enable Obiba Mica module
drush en -y obiba_mica

# Download and enable Obiba Agate module
drush en -y obiba_agate

# Download and enable Obiba Mica Data Access module (optional)
drush en -y obiba_mica_data_access_request

# Download Obiba Javascript dependencies
drush download-mica-dependencies

# Generate the autoload composer dependencies
drush composer-json-rebuild
cd sites/default/files/composer/
composer update
composer dump-autoload -o
# Choose option 9 (to clear registry cache)
drush cc registry

# Apply JQuery settings
drush vset -y --format=string jquery_update_jquery_version 1.10
drush vset -y --format=string jquery_update_jquery_admin_version 1.10

# Download and enable Autologout module (optional)
drush dl -y autologout
drush en -y autologout
drush vset -y autologout_redirect_url "<front>"
drush vset -y autologout_no_dialog TRUE
  • Debian
# Apply some folder permissions
chown www-data:www-data ./sites/default/files/composer/
  • CentOS
# Apply some folder permissions
chown apache\: ./sites/default/files/composer/

To enable the mode_rewrite on Debian:

sudo a2enmod rewrite
sudo service apache2 restart

On CentOS the rewrite_mode is enabled by default.

  • Make sure that the apache config on Debian and CentOS allow overriding via .htaccess, to do so make sure the apache config file has the following directive:
<Directory "/var/www/html">
AllowOverride All


Before proceeding, make sure that the PHP version is 5.6 and Mica server version is >= 2.0.0.

The following instructions apply when upgrading from obiba_mica 7.x-1.3 or older.

# Go to Drupal installation directory

# Upgrade Obiba modules
drush up obiba_mica
drush up obiba_bootstrap
drush up obiba_agate

# Install Obiba javascript dependencies
drush download-mica-dependencies

# Replace the old search module with the new one
drush dis obiba_mica_search
drush en obiba_mica_repository

# Generate the autoload composer dependencies
drush composer-json-rebuild
cd sites/default/files/composer/
composer update
composer dump-autoload -o
# Choose option 9 (to clear registry cache)
drush cc

# Install Obiba Agate module new dependency
drush en autologout

# Clear all caches
drush cc

If some templates have been overridden, please compare with the new original one.

If you have defined a sub-theme of obiba_bootstrap’s theme, you might need to update your style sheet.

Drupal 7.72

For the security issues you should update your Drupal installation to the latest version 7.72. Also, make sure to use the bootstrap-7.x-22 version. After that please follow these steps:

  • Install and enable the jquery_update-7.x-3.0-alpha5 version.
  • Go to the jQuery configuration page under <YourDrupalInstallation>/admin/config/development/jquery_update.
  • In “JQuery Migration” section check the “Enable JQuery Migrate Plugin” options, (do not enable the “JQuery Migration CDN”).
  • In the “Theme Override” section click on the “Configure” link of your enabled theme.
  • Once on the custom theme “Configuration” page check the 2.2 theme specific jQuery version under the “JQUERY UPDATE” section and click on “Save” configuration.
  • It may be useful to switch the default jQuery version to 2.2.
  • Clear your site cache.

These steps are recommended for anyone who updates the Drupal installation to 7.72.
