EDIT: The script below has been updated to work with Drush 3.x. Those using previous versions of Drush will need to edit the script appropriately. The nature of the change was to use the new Drush 3.x standard of no spaces with command names, so "drush sql dump" was changes to drush sql-dump."
Before using this script, make sure that all your contributed themes and modules are somewhere in the "sites/" directory. If they are in any other Drupal core directories, your modules and themes will be lost.
I run a handful of small Drupal sites that I can't afford to spend too much maintenance time on, but that still need to be updated with the occasional maintenance version of Drupal.
It can be quite time-consuming to manually update 4 or 5 sites each time a security release is published.
So, a couple months ago I spent an afternoon writing a shell script to automate the whole task. With a little help from Drush, it turns a 10 or 15 minute maintenance task into about 10 or 15 seconds.
Here's what it looks like.
$ drupal-upgrade 6.15 Putting site in offline mode... Backing up current Drupal core files... Done. Backing up current Drupal database... Done. Start downloading drupal-6.15.tar.gz... Done. Upgrading Drupal core files... Done. Upgrading Drupal database... No database updates required Cache cleared. Finished performing updates. Done. Putting site back online... Done. If something went horribly wrong type "restore" to restore from backup: Your upgrade is complete Backup files before the upgrade where saved in the following locations: /home/nathan/www/drupal-core.backup.tgz /home/nathan/www/drupal-upgrade.backup.sql.tgz
From the output, you can see that the script does the following:
- Take the site offline
- Backup the Drupal core files
- Backup the database
- Download the chosen version of Drupal
- Update the filesystem with the new version of Drupal
- Run any database updates (update.php)
- Put the site back online
Before the script finishes, it gives you the chance to restore both the filesystem and the database in case anything went horribly wrong.
Now updating to the latest maintenance release is a breeze.
Here is the script.
#!/bin/bash # A script to upgrade a Drupal installation to the next minor version # This script uses drush to initiate database updates; comment out lines beginning with "drush" if you don't have drush installed TMP="/tmp" # check for user input if [ ! $@ ]; then echo echo " Usage:" echo " $0 VERSION [DIRECTORY]" echo echo " VERSION: The new version to install" echo " DIRECTORY: The relative path to your Drupal installation; if blank the current directory is assumed" echo echo " Example usage:" echo " $0 6.9 public_html/" echo exit 0 fi VERSION=$1 if [ ! $2 ]; then SITEPATH="." else SITEPATH=$2 fi DRUPAL_VERSION="drupal-${VERSION}" DRUPAL_PACKAGE="${DRUPAL_VERSION}.tar.gz" TMP_FILE="${TMP}/${DRUPAL_PACKAGE}" cd $SITEPATH # Put the site offline echo "Putting site in offline mode..." drush vset --yes site_offline 1 > /dev/null # backup core files echo -n "Backing up current Drupal core files...

" yes | drush updatedb echo "Done." # Put the site back online echo -n "Putting site back online... " drush vset --yes site_offline 0 > /dev/null echo "Done." echo echo -n "If something went horribly wrong type \"restore\" to restore from backup: " read RESTORE if [ "$RESTORE" = "restore" ]; then echo -n "Restoring database... " MYSQL_CONNECT=$(drush sql-connect) $MYSQL_CONNECT < ../drupal-upgrade.backup.sql.tgz echo "Done." echo -n "Restoring files... " tar -xzf ../drupal-core.backup.tgz -C ./ echo "Done." drush vset --yes site_offline 0 > /dev/null echo "Your upgrade failed, but the backup was restored" else echo "Your upgrade is complete" fi BACKUP_DIR=$(readlink -f ../) echo "Backup files before the upgrade where saved in the following locations:" echo " ${BACKUP_DIR}/drupal-core.backup.tgz" echo " ${BACKUP_DIR}/drupal-upgrade.backup.sql.tgz"
To make the script available to any user on the command line, put it in the /usr/local/share directory then create a symlink from the /usr/local/bin directory.
$ mkdir /usr/local/share/drupal $ cp drupal-upgrade.sh /usr/share/drupal/drupal-upgrade.sh $ ln -s /usr/local/share/drupal/drupal-upgrade.sh /usr/local/bin/drupal-upgrade $ chmod 755 /usr/local/bin/drupal-upgrade

What about non-core modules?
Is there a way to automate saving status of, then disabling and re-enabling the non-core modules, to ensure nothing goes wrong there?
At least, I know the upgrade instructions always include to disable non-core modules, then re-enable after the upgrade.
I was thinking of how nice it'd be to automate the whole thing and include that. My thought is that couldn't you run a few queries to take care of this part, or is it possible to run queries from such a script?
Parents often prefer to use
Parents often prefer to use full-featured duo/tandem strollers. Such strollers are narrower than the other tandem strollers and they are easier to maneuver in tight spaces. However, the maneuvering becomes more difficult as children become heavier. Also graco duoglider is known for its durability and sturdiness.
No need that I see
There isn't a need to disable any modules if you are doing a minor release upgrade. You only need to do that if you are doing a major release upgrade, like from Drupal 5.x to 6.x.
Hello! And thanks for this
Hello! And thanks for this usefull script! With the command "up", Drush update, upgrade, and make a backup of the old files. You just need to make a backup of the db with the sql-dump command. Is there a special reason you didn't proceed that way? Greetings. MR
Air Jordan
Jordan lorsque michael jordan intégra le monde de la nba en 1984, ce ne fut pas seulement le début d'une carrière sans égal, mais aussi
le début de la série célèbre "Air Jordan" de nike. le fabricant d'articles de sport accorda toute
une série de chaussures et d'habits au basketteur doté apparemment de talents surhumain. cette série fit tout de suite sensation : l' Air Jordan 1 fut interdite par la nba puisque la combinaison des coloris noir/rouge ne
correspondit pas au "code vestimentaire" de la nba à l'époque. pourtant, cela ne put empêcher le succès mondial de cette sneaker unique.
au contraire : la chaussure de basket déclencha une véritable hystérie et est, dès lors, lancée dans une nouvelle édition chaque
année.jordan - plus qu'une simple chaussure de basket les spots publicitaires de jordan sont aussi innovateurs que les produits eux-
mêmes. au cours des années 80, avec spike lee alias mars blackmon, ils conquirent les écrans de la télé. aujourd'hui, les spots pour les
différents modèles d'air jordan sont toujours de vrais classiques sur youtube. de nos jurs, le jumpman ne se porte pas seulement sur les
chaussures : Air Jordan 3, Air Jordan
4, Air Jordan 5, Air Jordan 6,
Air Jordan 7, Air Jordan Spizike.
ils se distinguent par le design typique de la marque et convainquent par une excellente qualité et des matières hut de gamme. en 1997,
nike externalisa même la série de jordan : aujourd'hui, la marque de jordan développe ses propres produits, mais coopère néanmoins
étroitement avec nike. des joueurs comme carmelo anthony ou dwyane wade portent le jumpman dans la nba. ainsi, michael jordan reste
présent dans la meilleure ligue de basket-ball du monde. Obtenez les dernières Air
