Hi,I hope this is the right place! I have been having trouble installing VBulletin on Mysql. I have tried for a while now and cant get it installed... can someone help me with the error please

When i got to www.mywebsitename.com/install/install.php
i get this error:

The database has failed to connect because you do not have permission to connect to the server. Please confirm the values entered in the includes/config.php file

Error description: mysqli_real_connect() [function.mysqli-real-connect]: (HY000/2002): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) /home/content/23/7720423/html/includes/class_core.php on line 1317

Can someone help me fix this! I have no clue what to do, and im a beginner at this trying to learn, so some simple instructions would be greatly appreciated!

Probably the mysql server isn't running. Check
ps -e | grep mysql
on command line to see if so. If it is running the process number an d some details will be shown. If not you have to start the server first. The way you do that depends on the way you installed mysql. If it came with your distribution you can try
sudo /etc/init.d/mysql start

Im using godaddy to host my website, however from what i have read i cant access a command line to enter these codes to restart MYSQL. Am i correct about this?
What do you recommend i do, i just got vbulletin and i'm having trouble install it because of this error i get.
Some additional help would be appreciated!

Did you edit includes/config.php regarding the username and password you got from your provider?
