I have tried to install Drupal 7 over 20 times using every suggestion and trick that I can find. I run a set of websites for various non-profits, and several want to convert to Drupal 7. I do this as a volunteer since I am over 60 and have time on my hands. Been working with computers since 1968 and running online systems since 1985, so this is very humiliating.
Dreamhost, which used to have a one-click install fro Drupal 6, refuses to offer any assistance on Drupal 7. They know the install is crashing.
Sigh.
I am willing to help write an unofficial install manual for Drupal 7 on Dreamhost, since they have a great policy on hosting non-profits for free.
Here are some of the tricks I have tried:
create these directories by hand :
sites
sites/default
sites/default/files
Copy and rename new file
sites/default/default.settings.php
to
sites/default/settings.php
so that you end up with both files:
sites/default/default.settings.php
and
sites/default/settings.php
Edit settings.php
Now go to a command line prompt:
chmod a+w sites
chmod a+w sites/default
chmod a+w sites/default/files
chmod a+w sites/default/settings.php
