ERROR 1045 (28000): Access denied for user 'root'@'localhost'

[Lars Cedar]

I'm attempting to install Bugzilla.

I'm stuck because the last two modules that are required in Perl won't run. The apparent reason is that the root login fails.

I tried it manually to, and here's what I get:

[root@10 bugzilla-2.18.3]# mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

I created the database and login via a Perl module called template:

/opt/ActivePerl-5.8/bin/perl-static -MCPAN -e 'install "Template"'

Please help!

This is similar to another post, but I'm redoing is as less system specific, since I think the previous post scared potential readers away.
