While running symfony jobeet tutorial, i got following error

fwh@pc11-desktop:~/web/jobeet$ php symfony doctrine:build-sql
>> doctrine  generating sql for models

This is fixed by editing config/databases.yaml

Find line

dsn: 'mysql:host=localhost;dbname=jobeet'

Replace with

dsn: 'mysql:host=localhost;dbname=jobeet;unix_socket=/var/run/mysqld/mysqld.sock'
