Drush on centos

I have a problem with drush. I have install vestacp, after the composer globally and then i require via composer drush/drush:dev-master.

The drush download successfull the drupal and install it with site-install command but when i use drush for enable or upwd return: Command user-password 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 ‘upwd admin’ 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.

Drush was attempting to connect to: Drupal version : 7.26 Site URI : http://default Database driver : mysql Database username : admin_drupal Database name : admin_sitedb PHP executable : /usr/bin/php PHP configuration : /etc/php.ini PHP OS : Linux Drush version : 7.0-dev Drush temp directory : /tmp Drush configuration : Drush alias files : Drupal root : /home/admin/web/mydomain/public_html/ site Site path : sites/default

I try the solution of the link but nothing. Any ideas? I use centos 6.4 x64 + VestaCP the composer is ok.
