getting started with mysql

[Duncan Lithgow]

This seems kinda odd as well, I can get mysql as user, but not as root:

[dulithgow at 3e6b36fa ~]$ mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 4 to server version: 3.23.58

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> exit
Bye

[root at 3e6b36fa ~]# mysql
ERROR 1045: Access denied for user: 'root at localhost' (Using password: NO)
[root at 3e6b36fa ~]#
