Drush & Dreamhost

Submitted by abhishek on Wed, 04/14/2010 - 10:19

Its been more than a year since i am using Dreamhost, The basic package is not too great but is cheap and the support is responsive.

Drush or the Drupal Shell is one of the most powerful tools to use when you are working with Drupal. DreamHost provides php5 but uses php4 as the default for the php command line and in that case drush wont work, so here is a 3 step guide to setup drush on your dreamhost account.

  1. Download & Extract Drush some where on your home folder
  2. Add the following lines to .bash_profile using your favorite editor.

    export PATH=/usr/local/php5/bin/:$PATH
    alias drush='/home/username/drush/drush'

    replace the path of drush as per your preferences :)

Key Based Authorization with SSH

Submitted by abhishek on Wed, 08/26/2009 - 19:09

Using remote shells is all time favourite but remembering those many passwords is a pain so here are the steps to login using SSH without putting a password :)


1. Create a public ssh key, if you haven’t one already. Look at ~/.ssh. If you see a file named then you obviously already have a public key. If not, simply create one.

ssh-keygen -t dsa should do the trick. Please note that there are other types of keys, e.g. RSA instead of DSA.

2. Make sure your .ssh dir is not publically writable

    # chmod 700 ~/.ssh
