I download from https://github.com/luciddreamz/laravel Laravel for openshift then upload over my repository over github. This code for connect to database not work. The problem is that load variable from .env file that locate in root of project

for solve this problem change.env

# local environment only #   for production, see .openshift/.env  APP_ENV=APPLICATION_ENV APP_DEBUG=true APP_URL=OPENSHIFT_APP_DNS APP_KEY=OPENSHIFT_SECRET_TOKEN  DB_DRIVER=mysql DB_HOST=OPENSHIFT_MYSQL_DB_HOST DB_PORT=OPENSHIFT_MYSQL_DB_PORT DB_DATABASE=OPENSHIFT_APP_NAME DB_USERNAME=OPENSHIFT_MYSQL_DB_USERNAME  DB_PASSWORD=OPENSHIFT_MYSQL_DB_PASSWORD  CACHE_DRIVER=apc SESSION_DRIVER=file 

my error :

SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name or service not known  createConnection('mysql:host=OPENSHIFT_MYSQL_DB_HOST;port=OPENSHIFT_MYSQL_DB_PORT;dbname=OPENSHIFT_APP_NAME',  array('driver' => 'mysql',        'host' => 'OPENSHIFT_MYSQL_DB_HOST',        'port' => 'OPENSHIFT_MYSQL_DB_PORT',        'database' => 'OPENSHIFT_APP_NAME',        'username' => 'OPENSHIFT_MYSQL_DB_USERNAME',        'password' => 'OPENSHIFT_MYSQL_DB_PASSWORD',        'charset' => 'utf8',         'collation' => 'utf8_unicode_ci',        'prefix' => '',        'strict' => false,        'name' => 'mysql'),  array('0', '2', '0', false, '0')) in MySqlConnector.php line 20 

Answer 1

First line of the error message describes the error type: "PDOException". The next line displays PDO::errorInfo, i.e:

1. SQLSTATE error code (a five characters alphanumeric identifier defined in the ANSI SQL standard).
2. Driver-specific error code.
3. Driver-specific error message.

• "HY000" is a general server error (see Server Error Codes and Messages in MySQL docs).
• "2002" is MySQL Client Error Code meaning "Can't connect to local MySQL server through socket" (see (Client Error Codes and Messages in MySQL docs).
• The driver specific error code and message ("php_network_getaddresses: getaddrinfo failed: Name or service not known") tell you that PDO is not able to resolve the host name.

The stack trace you attached, line 3, reveals that you did not specify the database connection parameters in the configuration file. The error show up when you test on local, right? You need to update /.env with the actual database connection parameters.

Answer 2

Check your DB_HOST on your .env file

DB_HOST=http://localhost/ --> DB_HOST=localhost
