[root@AY1403072133429290dbZ www.penghuajun.com]# drush en views -y
Command pm-enable needs a higher bootstrap level to run - you    [error]
will need to invoke drush from a more functional Drupal
environment to run this command.
The drush command 'en views' could not be executed.              [error]
Drush was not able to start (bootstrap) the Drupal database.     [error]
Hint: This may occur when Drush is trying to:
 * bootstrap a site that has not been installed or does not have
a configured database. In this case you can select another site
with a working database setup by specifying the URI to use with
the --uri parameter on the command line. See `drush topic
docs-aliases` for details.
 * connect the database through a socket. The socket file may be
wrong or the php-cli may have no access to it in a jailed shell.
See http://drupal.org/node/1428638 for details.
