install error

I decided to start over and reinstall my VShare and start from scratch. But after I uploaded all the files in Binary mode I got an error when I tried to run my mysql stuff to my database. I got the following error below. Do you know what I am doing wrong? I downloaded the product again so all the files are fresh and never touched.

Code:

---

ERROR: Unable to execute query

SELECT * from signup where username='jeremy' and pwd='c5a6c7f52358c29b33831530a9fb35c6'

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

---

I tired a couple of other times changing some things around and I got it to work! :D

The problem due to the following reason

1.The script is not able to connect to MySQL with user name and password provided.

Please make sure you have enter the correct details in include/config.php

2.MySQL server is down
