Drush

About Drush

Drush is an awesome command line interface for Drupal

If you have multiple sites (and even in cases of single site use) and you are not using Drush, you are missing out

Installing Drush:

 
  • First we need to download drush through pecl:
pear channel-discover pear.drush.org
pear install drush/drush
 
now, you can check drush is installed by typing “drush from command line”
  • In centos, default php settings are too restrictive so we need to make a drush.ini that allowes exec:
_ mkdir /etc/drush
_ cp /usr/share/pear/drush/examples/example.drush.ini /etc/drush/drush.ini
 
when done, uncomment the disable_function=”” line
