Better to use Malcolm’s Drupal Update Notes


Make sure you have a recent backup of your site.

To check the current version of your site, browse to https://www.mydrupalsite.com/admin/reports/status

Download the latest Drupal update e.g. drupal-8.6.10.tar.gz.

Copy the tar.gz file to the server:

scp drupal-8.6.10.tar.gz  www.mydrupalsite.com:repo/temp/

Copy the update archive to the deploy folder:

sudo -i
cd /home/web/repo/project/www.mydrupalsite.com/deploy
mv /home/patrick/repo/temp/drupal-8.6.10.tar.gz .

Make sure the folder doesn’t already contain a drupal-8.6.10 folder.

Extract the update:

tar xzf drupal-8.6.10.tar.gz
cd drupal-8.6.10/

# copy our code from the previous version of the site
cp -r ../../live/sites/* sites/
# note: our site does not use 'themes', 'profiles' or 'modules'

Make a note of where the ‘live’ folder is currently pointing to (so you can put it back if the update fails).

Put the site into maintenance mode:


Link the new code to the live folder:

ls -l /home/web/repo/project/www.mydrupalsite.com/
# e.g. live -> deploy/0_0_01__20190117_135225_malcolm


rm /home/web/repo/project/www.mydrupalsite.com/live
ln -s /home/web/repo/project/www.mydrupalsite.com/deploy/drupal-8.6.10 /home/web/repo/project/www.mydrupalsite.com/live

Clear the cache (and update the database) by browsing to https://www.mydrupalsite.com/update.php


I didn’t think I needed to clear the cache, but I think it rebuilds the twig files which are the Drupal templates!

Update permissions:

chown www-data:www-data sites/default/files
chown -R www-data:www-data sites/default/files/


  1. The update needs to be done by the root user. I think it should be web?

  2. The files folders do not contain any files: /home/web/repo/files/www.mydrupalsite.com/public/ /home/web/repo/files/www.mydrupalsite.com/private/ Why are the files for the Drupal site not in these folders?



See the PHP - Install documentation

With regard to the Salt scripts you asked about:

  • restore.sh restores the drupal files from a compressed tar backup

  • restore_db.sh restores a mysql database from an SQL script.

I created them so we could restore the journal system from a snapshot and modified them for use in the upgrade to Drupal 8. I thought the best place for them was in the Salt configuration.

To use them in the current configuration we would need to restore the files backup and create a compressed tar and restore the database backup.
