1. I started with a working site and performed the following steps to add a second one
2. Create a symlink, making the /backend a symlink to the web root:

ln -s backend .

2. Add entries to my sites.php (because with our deployment workflow, the site name cannot always match with the domain name. Also allows us to test with xip.io).

$sites['mysite.dev'] = 'mysite';

$sites['mysite.dev.backend'] = 'mysite.backend';

3. I created a directory named mysite.backend .
4. In mysite.backend, I created a directory corresponding to all directories in mysite.
5. In mysite.backend, I created the following settings.php file:

$databases = array (

'default' =>

array (

'default' => 

array ( 

 'database' => 'XXXXXX', 

 'username' => 'XXXXXX', 

 'password' => 'XXXXXX', 

 'host' => 'localhost', 

 'port' => '', 

 'driver' => 'mysql', 

 'prefix' => '', 

), 

),

);

$update_free_access = FALSE;

$drupal_hash_salt = 'k_vtgGjzCyq0mp0dsxDk1gILuEs6G5ODP5aJuQsAUuc';

$base_url = 'http://mysite.dev/backend'; // NO trailing slash!

ini_set('session.gc_probability', 1);

ini_set('session.gc_divisor', 100);

ini_set('session.gc_maxlifetime', 200000);

ini_set('session.cookie_lifetime', 2000000);

6. I go to /backend/install.php and go through the install process. Everything goes smoothly
7. I click the link to view the new site, and enter the admin login credentials (for the new site. I made it a point to have separate logins for each site)
