Multisites with shared codebase, multiple databases, local install

Hi,

I've read through all the posts I could find on the subject of installing multisites with a shared codebase. I'm trying this locally under MAMP on OS X. I've tried this solution http://drupal.org/node/25011 and this one http://drupal.org/node/69199#comment-129840 without success.

Here are the settings I'm using:

I have the main drupal install in /cms

In the sites directory I have 127.0.0.1.cms.site01

In httpd.conf I have the following:

Alias /checkdisc /Applications/MAMP/htdocs/cms

AllowOverride All
Options +Indexes
DirectoryIndex index.php
Order allow,deny
Allow from all

and in the .htaccess file in the /cms dir I have:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} ^/cms/(.*)$
RewriteRule ^(.*)$ /cms/index.php?q=$1 [L,QSA]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} ^/site01/(.*)$
RewriteRule ^(.*)$ /site01/index.php?q=$1 [L,QSA]

I'm a little confused as to what the url is to access site01. Would it be http://127.0.0.1/cms/site01 ?

I can't get anything to work except the main drupal install. Any help would be greatly appreciated.

Thanks!
