New install of AAH 2.7 - AMP admin page not working

Not sure what I’ve done - was a manual install from a .tar and I ended up manually re-installing amp after doing some yum updates to mysql.

Anyway, if I now navigate to AMP and click the admin link, after logging in as maint, I get the following response:

mysql://asteriskuser:amp109@localhost/asterisk

Figuring that asterisk database is not installed, I run:

mysqladmin create asterisk

And I get:

mysqladmin: connect to server at ‘localhost’ failed
error: ‘Access denied for user ‘root’@‘localhost’ (using password: NO)’

Any help appreciated.

Thanks.
