Unable to connecte to the database

No just run the code from straight php

Hello everyone

Thanks so much for the prompt guide you are giving me. I have used the suggested code of InsiteFx in my index.php (in a manner that eliminates CI) and still could not connect to the DB. The error msg is:

"Failed to Connect to MySQL: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)"

Thanks in advance for further suggestion.
