I have a slight issue in connecting Drush to my MAMP localhost DB. Already tried multiple solutions like changing host from localhost to, and editing MAMP files like this suggestion.

It seems my socket location is slightly different from most examples I see on the web, being var/mysql/mysql.sock rather than tmp/mysql.sock. I installed via homebrew, if that's helpful.

Super new to drush, and command line in general, so any help much appreciated. All file transfers (like dl) work fine, just anything DB related throwing an error. Thanks!

    PDO::__construct(): [2002] No such file or directory (trying to connect  [warning]
via unix:///var/mysql/mysql.sock) environment.inc:523
Command pm-enable needs a higher bootstrap level to run - you will need  [error]
to invoke drush from a more functional Drupal environment to run this
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
 * 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:

  • Did you just try installing drupal via the install.php file? – chadpeppers Dec 10 '13 at 21:12
  • Yes, D7 is up and running on localhost, no issues there. The issue is solely around connecting Drush to that DB. Thanks for checking! – Daniel Rogers Dec 10 '13 at 21:32
  • you also tried the symlink ? (like: ln -s /tmp/mysql.sock /var/mysql/mysql.sock) – rémy Dec 10 '13 at 22:51
  • Remy, yes, just tried that as well with no luck. Does the unix:/// in front of the socket path affect that? – Daniel Rogers Dec 11 '13 at 0:19
  • The background for truly troubleshooting and arriving at the answer above is clearly explained over in this gem of a post: drupal.stackexchange.com/a/174128/3167 which is conveniently hidden away due to a non-generalized post title, so I'm sharing here for the next time I stumble upon this issue and forget exactly what to search for to find that post! – JamesWilson Aug 17 '16 at 16:35

OK, finally got it working:

sudo mkdir /var/mysql
sudo ln -s /Applications/MAMP/tmp/mysql/mysql.sock /var/mysql/mysql.sock

Thanks to Remy for putting me on the right track, and This drupal.org post.

Seems it was that I needed to make a directory first... Rookie move.
