# doctrine configuration doctrine:     dbal:         driver:   pdo_mysql         host:     "%database_host%"         port:     "%database_port%"         dbname:   "%database_name%"         user:     "%database_user%"         password: "%database_password%"         charset:  utf8         server_version: 5.6         # if using pdo_sqlite database driver:         #   1. add path in parameters.yml         #     e.g. database_path: "%kernel.root_dir%/data/data.db3"         #   2. uncomment database_path in parameters.yml.dist         #   3. uncomment next line:         #     path:     "%database_path%"      orm:         auto_generate_proxy_classes: "%kernel.debug%"         naming_strategy: doctrine.orm.naming_strategy.underscore         auto_mapping: true 

my config_prod.yml

imports:     - { resource: config.yml }  #framework: #    validation: #        cache: validator.mapping.cache.apc #    serializer: #        cache: serializer.mapping.cache.apc  #doctrine: #    orm: #        metadata_cache_driver: apc #        result_cache_driver: apc #        query_cache_driver: apc  monolog:     handlers:         main:             type:         fingers_crossed             action_level: error             handler:      nested         nested:             type:  stream             path:  "%kernel.logs_dir%/%kernel.environment%.log"             level: debug         console:             type:  console

[doctrine\dbal\exception\connectionexception]                                                                         exception occured in driver: sqlstate[hy000] [1045] access denied user ''@'localhost' (using password: no)
