Step 3: setting the subdirectories

Bulk loop 2

• Copy directory /var/www/drupal7/sites/default as /var/www/drupal7/sites/example.com  .
• Give read and write permissions to everybody for that directory and for /var/www/drupal7/sites/example.com/files/ .
• If the file /var/www/drupal7/sites/example.com/settings.php doesn't exist yet, copy /var/www/drupal7/sites/example.com/default.settings.php to /var/www/drupal7/sites/example.com/settings.php .
• Search the line beginning by "$databases" and modify that paragraph like this:
  

  $databases['default']['default'] = array(
     'driver' => 'mysql',
     'database' => 'company_example',
     'username' => 'company_example',
     'password' => 'my_password',
     'host' => 'localhost',
     'prefix' => '',
     'collation' => 'utf8_general_ci',
  );
  

  replacing the 1st occurrence of "company_example" by the database schema's name, "my_password" by your password, and, if you have created another database user representing Drupal in the schema, replace also "company_example" by its name. If you have installed mysqli, replace "mysql" by "mysqli".

End of bulk loop 2
Copy /var/www/drupal7/sites/example.sites.php to /var/www/drupal7/sites/sites.php .

Bulk loop 3

• At the end of /var/www/drupal7/sites/sites.php , add the following line:
  $sites['example'] = 'example.com';
  replacing "example" by the website short name, and "example.com" by the directory name.
