title: Drush. Command pm-enable needs a higher bootstrap level to run
body: <p>I have started to learn Drupal on this week and I have installed the drush on my virtual machine with CenOS ( Drupal version:  7.28,  Drush version:  7.0-dev). I installed drupal using drush by command: drush dl --drupal-project-rename=mysite
  and downloaded some moduls by command: drush dl admin_menu ctools views ...
  But when I want enable these moduls in Drupal by command: drush en -y admin_menu_toolbar ...
  I have errors: 
  Command pm-enable needs a higher bootstrap level to run - you will need to invoke drush from a more functional Drupal environment to[error]
  run this command.
  The drush command 'en admin_menu' could not be executed.                                                                            [error]
  Drush was not able to start (bootstrap) the Drupal database.                                                                        [error]</p>
  
  <p>I changed the code in the file /sites/default/settings.php</p>
  
  <pre><code>'host' =&gt; 'localhost', to 
  'host' =&gt; php_sapi_name() == 'cli' ? '127.0.0.1' : 'localhost',
  </code></pre>
  
  <p>but it still does not work.</p>
  
  <p>Tell me please how can I fix it?</p>
  
  <p>If I use command "drush si standard --db-url=mysql://user:password@localhost/db_name" database is create and drupal install. But when I try to sign in using provided username and password server answer me "404 Not found". </p>
