So a year ago I’ve done a freelance drupal job, you know, the kind of quick-and-dirty-money-freelance-job that you completely wipe of your memory after is done, and it came back to bite my ass, no surprises there. So I needed to change some stuff over here and fix other over there, but a year ago I didn’t even bother on using drush, now I can’t live without it on my Drupal projects.

A quick word about Drupal on Dreamhost: don’t, really, don’t do it. The Dreamhost shared servers are so overselled that are completely drained of resources. So if you don’t want to have a painfull experience with a CMS like Drupal, Wordpress, Joomla, whatever-thing-that-uses-lots-of-tables, just don’t hire the shared services. Go for the VPS o Cloud services. Or better yet, go for Digital Ocean.

Anyway, quick steps for installing Drush on your Dreamhost shared account. First of all, you will need to login via SSH to your host, also, since is a shared account, you need to make this changes only for you. Also, you will be installing drush via PEAR, so we will set up PEAR first.

• Create an instance of PEAR

pear config-create ${HOME} ${HOME}/.pearrc
pear install -o PEAR

• Edit your ~/.bash_profile file and add the following lines at the end of it
  export PHP_PEAR_PHP_BIN=/usr/local/php53/bin/php
export PATH=${HOME}/pear:/usr/local/php53/bin:${PATH}

• Reload your bash profile
  . ~/.bash_profile

• Now install that cheeky Drush
  pear channel-discover pear.drush.org
pear install drush/drush

All done. Piece of cake.
I took all this easy instructions from Robin Monks. So all credits for him.
Also, he suggests all the instructions in one single line, pretty neat, isn’t it?

pear config-create ${HOME} ${HOME}/.pearrc;pear install -o PEAR;echo "export PHP_PEAR_PHP_BIN=/usr/local/php53/bin/php" >> ~/.bash_profile;echo 'export PATH=${HOME}/pear:/usr/local/php53/bin:${PATH}' >> ~/.bash_profile;. ~/.bash_profile;peuar channel-discover pear.drush.org;pear install drush/drush
