If you're passing undef for the user name, the script will try to connect
as whatever user is running the script.  I assume that when you can "a
script is run locally on the server", you mean the case where you invoke
it manually from the command line?  In that case, the script sends your
name as the user name.  When the script is invoked from the Web server,
the script sends the user name of the user the server runs as.  Given
that the error message says "root", my guess is that the Web server runs
as root.  (Not a good idea, by the way.)

You could either explicitly specify your MySQL user name and password
in the script (perhaps not a good idea, although you might try it just
to see if it works, and then make them undef again), or you can tell
the script to read a MySQL option file, and store the name and password
in that file.  I usually do something like this:

# construct data source
my ($dsn) = "dbi:mysql:db_name_here";
$dsn .= ":hostname=$host_name" if $host_name;
$dsn .= ";mysql_read_default_file=/path/to/some/option/file";

# connect to server
my (%attr) = ( RaiseError => 1 );
my ($dbh) = DBI->connect ($dsn, $user_name, $password, \%attr);
