Check list:

• Get MAMP: MAMP Download
• Get Drupal: Drupal Download | Get WordPress: WordPress Download

MAMP sets up an Apache, MySQL, PHP stack on your desktop.

For multiple sites I use the Hosts feature in MAMP Pro.

So I created a “Drupal7″ and “WordPress3″ Host pointing to “/code/drupal7″ and “/code/wordpress3″

Moved the downloaded files to there respective locations “/code/drupal7″ and “/code/wordpress3″

Modified the Permissions for each site:

Created the databases:

Server >> MySQL >> Launch phpMyAdmin

Create new Database – “drupal7″ and “wordpress3″

Then created users for those databases

drupal7 >> Privileges >> Add a new User
drupal_user
with all ‘Grant all privileges on database “drupal7″‘ selected

wordpress3 >> Privileges >> Add a new User
wp_user
with all ‘Grant all privileges on database “wordpress3″‘ selected

Once all this is done go to the browser and point it to your sites and run configurations.

Done.
