UNLcms 2

Drupal 8 installation at the University of Nebraska–Lincoln

Installation

1. Install Composer (https://getcomposer.org/download/) and Drush version 8 (http://docs.drush.org/en/master/install/). Latest Drush tested and verified is 8.1.11.

• Production uses http://www.imagemagick.org/script/download.php. You can optionally skip installing this and switch to the core GD2 toolkit at admin/config/media/image-toolkit.

2. Clone this project and run from this project's root:

cp .htaccess.sample .htaccess
cp sites/default/default.settings.php sites/default/settings.php
mkdir sites/default/files
sudo chown _www sites/default/files
sudo chmod 777 sites/default/settings.php
sudo chmod 777 sites/default/files

3. If installing in a directory such as http://localhost/workspace/UNL-CMS-2 edit .htaccess and change

# RewriteBase / to RewriteBase /workspace/UNL-CMS-2

4. Run

composer install

5. Do standard Drupal install:

• Navigate to /index.php in the browser
• Choose "Configuration installer" for the "installation profile"
• On "Configure site" set "Username" to "admin" and set "Email address" to a personal address so it doesn't conflict with your UNL email

6. Run:

drush entity-updates
sudo chmod 755 sites/default/settings.php
sudo chmod 755 sites/default/files/

7. Install the UNLedu Framework (https://github.com/unl/wdntemplates) separately and create a symlink to its 'wdn' directory.

• For example, if you installed the wdntemplates project in /Library/WebServer/Documents then you would run this from your UNL-CMS-2 project root:

ln -s /Library/WebServer/Documents/wdntemplates/wdn wdn

8. Run:

drush user-create jdoe2
drush user-add-role "administrator" jdoe2

The reason we create an admin user first, then create a second account is that the first user in a Drupal installation has special permisisons. We want to operate without that complexity. See https://www.drupal.org/node/540008

9. Enter the domain of your dev machine at admin/config/system/group_subdomain

10. That's it for installation. Instructions below are for additional site maintenance and updating tasks.

Update core

• Run composer update drupal/core --with-dependencies
• Replace files (such as update.php) except for
  • .htaccess.sample (and your site's .htaccess)
  • index.php
  • composer.json
  • composer.lock
  • robots.txt
  • sites/ directory including sites/default/default.settings.php
• Manually update the above files with the latest changes
• Run drush updatedb

Adding a module

• Example for adding the IMCE module: composer require drupal/imce
• Enable the module in the UI and configure
• Export the configuration and commit using "Managing configuration" below

Updating a module

• Run command to update a module composer update vendor/module. For example: composer update unlcms/unl_cas as this will only update the specific module and nothing else.
• Make edits to the configuration in the Drupal UI if needed
• Follow "Managing configuration" below
• Once the module update is pushed to production, run update.php there

Managing configuration

• Requires Drush 8+: http://docs.drush.org/en/master/install/
• git pull so you have the latest /config files
• Make sure your local dev site is using the latest config by running this from the site root drush config-import
• Make configuration changes on a local dev site and run drush config-export
• Commit changes to /config dir
• Do a pull request

Production deployment

• composer install --no-dev
• drush updb
• drush config-import --partial IMPORTANT: Must use the '--partial' flag so that existing group menus and webforms are not deleted.
• drush cr
