I know how to install a single instance of Drupal very well but I want to create a number of sub-sites under my Drupal installation. My file structure is as follows:
drupal7_main
-sites
--drupal7_sub1
settings.php
--drupal7_sub2
settings.php
I'm developing on my localhost and the plan is to duplicate the structure on the production server.
However, only drupal7_main works. When I visit localhost/drupal7_main, Drupal is ready and configurable as usual; when I visit localhost/drupal7_sub1, I get the following error.
Not Found
The requested URL /drupal7_sub1 was not found on this server.
I get the same for drupal7_sub2.
I'm trying to learn this process and would appreciate some help.
