Database problem
Permalink 1 user found helpfulSQLSTATE[HY000] [2002] Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
I am not running my ḿySQL on a localhost, i run at different server

Good luck!
in the file 'concrete5.7.0.3/concrete/src/Database/Connection/PDOConnection.php'
In the __construct, I added as first line of the method:
$dsn = 'mysql:host=MY_SERVER;dbname=MY_DB';
So I kept 5.7.0.3 for the other fixes, a pity that the problem is not fixed yet as it was not present in 5.7.0.1...
/concrete/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php
http://www.concrete5.org/developers/bugs/5-7-0-3/database-connectiv...
Fixed it by changing the variables name in :
\concrete\src\Database\Driver\PDOMySqlConcrete5\Driver.php
36 if (isset($params['server']) && $params['server'] != '') {
37 $dsn .= 'host=' . $params['host'] . ';';
38 }
to
36 if (isset($params['host']) && $params['host'] != '') {
37 $dsn .= 'host=' . $params['host'] . ';';
38 }
