Can't connect to LimeSurvey database. Reason: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

/// Basic Setup
$databasetype = 'mysql'; // ADOdb database driver - valid values are mysql, mysqli, odbc_mssql, mssql_n, odbtp or postgres
// mysql:
Recommended driver for mysql
// mysqli: Slightly faster driver for mysql - not on all server systems available
// odbc_mssql: MSSQL driver using ODBC with MS SQL Server
// mssql_n: Experimental driver for MS SQL Server which handles UTF-8 charsets
// odbtp: ODBTP driver to access MSSQL-Server is needed for this one - we also recommend to activate $databasepersistent for decent speed
// postgres: Standard postgres driver
$databaselocation = 'localhost'; // Network location of your Database - for
odbc_mssql use the mssql servername, not localhost or IP

$databasename = 'ncsac4pd_lime'; // The name of the database that we will create
$databaseuser = 'ncsac4pd_lime'; // The name of a user with rights to create db (or if db already exists, then rights within that db)
$databasepass = 'correctly entered in actual file'; //
Password of db user
$dbprefix = 'lime_'; // A global prefix that can be added to all LimeSurvey tables. Use this if you are sharing
// a database with other applications. Suggested prefix is 'lime_'
// File Locations
$rooturl = "http://{$_SERVER}"; // The root web url for
your limesurvey installation (without a trailing slash).
// The double quotes (") are important.

$rootdir

= dirname(__FILE__); // This is the physical disk location for your limesurvey installation. Normally you don't have to touch this


// setting. If you use IIS then you MUST enter the complete rootdir e.g. : $rootDir='C:\Inetpub\wwwroot\limesurvey'!
// Some IIS

and OS/2 installations also require to use forward slashes
// instead of backslashes, e.g. $rootDir='C:/Inetpub/wwwroot/limesurvey'!

// Installation Setup
$defaultuser = 'stmoist'; // This is the username when LimeSurvey is installed and the administration user is created on installation
$defaultpass = 'c4pd;131'; // This is the password for the administration user when LimeSurvey is installed

// Debug Settings
$debug = 0;

// Set this to 1 if you are looking for errors. If you still get no errors after enabling this
// then please check your error-

logs - either in your hosting provider admin panel or in some /logs dir
// on your webspace.


// LimeSurvey developers: Set this to 2 to circumvent the restriction to remove the installation directory
// or to change the

password. If you set it to 3 then PHP STRICT warnings will be shown additionally.
