We have a new CentOS installation using PHP5 and MySQL.  We were having an issue getting Cacti running, but the problem appears to boil down to a PHP issue.

When attempting to access Cacti via the web, we got this error:

FATAL: Cannot connect to MySQL server on 'localhost'. Please make sure you have specified a valid MySQL database name in 'include/config.php'

We checked config.php and everything is configured correctly.

We then looked at "my.cnf" and saw this line:
socket=/var/lib/mysql/mysql.sock

Running "netstat -an | grep mysql" says the following:
unix  2      [ ACC ]     STREAM     LISTENING     11035  /var/lib/mysql/mysql.sock

However, we have to create a symbolic link in /tmp in order to be able to get to the Cacti config screen:
ln -s /var/lib/mysql/mysql.sock mysql.sock

Why do we have to do this though?
