Unable to run drush commands in developer portal.

[#1]

Unable to run drush commands, while running the command getting error-

[root@xyz html]# /usr/local/bin/drush dc-getorg

The drush command 'dc-getorg' could not be found. Run `drush cache-clear drush` to clear the commandfile cache if you have installed new extensions. [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-php533patch.zip

First Check the drush version and PHP version

==> drush --version

There is an issue with drush 7.x version running on PHP 5.3.3, which the attached patch (drush-php533.patch) resolves.

You will need to do the following: cd /usr/local/share patch -p0 < /path/to/drush-php533.patch

/** Note - You can also change the PHP version from your Pantheon dashboard by clicking the "Settings" gear at the top right, then selecting the "PHP Version" tab.

More recent on-prem install packages will apply this patch for you. Additionally, if you are doing a fresh install, the 4.16.09.00 installer will install PHP 7.0.x and drush 7 on Red Hat or CentOS 6 or 7, which entirely eliminates this problem.
