php - Symfony error : Cannot connect to DB after DB update -


i had symfony 2 website connected mysql db, find, after changing contract host provider, needed tu update datas on new db, new names. created new db, php myadmin shows me fine on side.

i updated paramaters.yml file follow in symfony project:

parameters: database_host: newdbhostname.db.1and1.com database_port: 3306 database_name: newdbname database_user: newdbusername database_password: ********** mailer_transport: mail mailer_host: null mailer_user: null mailer_password: null secret: *sameasbefore*

but since then, cannot connect db, , have weird error:

warning: pdo::__construct(): php_network_getaddresses: getaddrinfo failed: name or service not known in /homepages/37/d627732413/htdocs/billetterielouvre/vendor/doctrine/dbal/lib/doctrine/dbal/driver/pdoconnection.php on line 43

this part corresponds to:

    public function __construct($dsn, $user = null, $password = null, array $options = null)     {         try { line 43 --> parent::__construct($dsn, $user, $password, $options);               $this->setattribute(pdo::attr_statement_class, array('doctrine\dbal\driver\pdostatement', array()));             $this->setattribute(pdo::attr_errmode, pdo::errmode_exception);         } catch (\pdoexception $exception) {             throw new pdoexception($exception);         }     }

i cleared cache through ssh on server, still error happens. have idea me find needs fixes there ?

thanks!

you should clean cache.

rm -rf app/cache/*

does new provider allow connecting external networks?

try creating script in plain old php , see if can connect

with ssh on server, can resolve host of db? try nslookup newdbhostname.db.1and1.com , telnet newdbhostname.db.1and1.com 3306
