Problem after install..... HELP

I ran the install util created the database files fine, the next step was configure admin page. I got this error when i clicked ok....

Warning: mysql_connect(): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) in /data/5/0/155/19/318671/user/324289/htdocs/guestbook/lib/mysql.class.php on line 30
Connection Error

I tried to edit this file with the same host, username and password and database name as the install program asked for but no luck.....
Thanks.....

Sounds like your database server is not on the same machine as your site. Best asking your host.

I am on a network solutions hosted site, the database is on the local machine, but you must create the base , give a user name and passwork and it gives you a ip address. I used this to create the tables and it worked fine tables were created. I checked and they were there.
but the next step was to go to the admin and thats where i got the error above. so I looked at that line and all fields were default, nothing changed, so i tried to change them myself with my database info but no luck. dont know if i did it right, but am now stuck......
thanks....

So it installed fine but the book it's self does not work?

Well i was using the novice installation, with the installer, so after it created the tables on the first step, it said next admin setup and thats where i got the error, so i look at the file in error line 30 and it was paths and username, address to the database, they were all at default, so even though i put them in, in the first step of installition and the tables were created, the file mysql.class.php never was updated, that is when I tried to do it manually but never could get it to connect to the server, If that makes any sense, I am new to php as you could have guessed, but much html and cgi script installation experience....
Thanks....

Ah well did you edit the config.inc.php file in the admin folder to reflect your database details?
