Installing and Updating Drush¶
An important note: we no longer need to install any version of Drush except Drush 8, since that now supports Drupal 6, 7, <8.3 and Backdrop.
Installing and updating Drush 8 for all users¶
These instructions follow the "Install a global Drush via Composer" instructions under in the Drush 8 alternative installation documentation.
If needed, follow this Composer documentation to install or update Composer on the server.
composer install as root is a security risk, you can use commands like these to install or update Drush in your home directory first, then move it to a globally-accessible location using
cd ~ COMPOSER_HOME=$HOME/drush COMPOSER_VENDOR_DIR=$HOME/drush/8 composer require drush/drush:8.4.11 cd ~/drush/8/drush/drush composer install cd ~ sudo rm -rf /opt/drush; sudo mv ~/drush /opt/ sudo chown -R root: /opt/drush sudo rm /usr/local/bin/drush; sudo ln -s /opt/drush/8/drush/drush/drush /usr/local/bin/drush
Replace "8.4.11" (last updated in this documentation on 12/04/2022) with the tag of the most recent stable 8.x release (see https://github.com/drush-ops/drush/releases)
If you must run
composer install and the other commands above as root, e.g. if that's the only user we have access to on the server, you can do so by changing the
COMPOSER_HOME path to
/opt/drush/8 and adjusting the other commands above accordingly.
Use the same commands with a new version number to update Drush as needed; the commands above account for updates.
Install and update Drush Backdrop commands¶
In order for Drush to work with Backdrop, you must install the Drush Backdrop commands within the Drush 8 installation itself.
Assuming that Drush 8 is installed in
/opt/drush/8/drush/drush, as specified above:
sudo git clone https://github.com/backdrop-contrib/drush.git /opt/drush/8/drush/drush/commands/backdrop
To update Drush Backdrop commands installed like this:
cd /opt/drush/8/drush/drush/commands/backdrop sudo git pull origin
Install Drush on May First Movement Technology and other shared hosting environments¶
Primarily drawn from this MF ticket; thanks Ivan!
First, install Composer following these instructions.
Then to install Drush:
echo 'export PATH="$HOME/.composer/vendor/bin:$PATH"' >> ~/.bashrc source ~/.bashrc cd ~/<organization.org>/bin composer global require drush/drush:8.4.10 which drush
Note that sometimes
cgi-bin is present on MF/PL sites instead of
If using Drush aliases, you may need to specify the new Drush installation in the shared
aliases.drushrc.php file or a local aliases file. Here's an example:
$aliases['organization'] = array( 'remote-host' => 'organization.org', 'remote-user' => 'organization', 'root' => '/home/members/organization/sites/organization.org/web', 'uri' => 'organization.org', 'path-aliases' => array( '%drush-script' => '/home/members/organization/sites/organization.org/users/organization/.composer/vendor/bin/drush', '%dump-dir' => '~/drush-backups', '%files' => '/home/members/organization/sites/organization.org/web/sites/default/files',), );
