#1045 Cannot log in to the MySQL server
 -- PHPMyAdmin

[xerrao@VicsVPS mysql-gui-tools-5.0]$ mysql -u xerrao -p
Enter password:
ERROR 1045 (28000): Access denied for user 'xerrao'@'localhost' (using password: YES)
 -- MySQL cli
 -- MySQL GUI tools

Any created users can not log in, only root.  Tried "FLUSH PRIVILEGES;", with result of:
110215 20:39:33 [ERROR] Can't open and lock privilege tables: Table 'mysql.servers' doesn't exist

When using CLI, root needs to have a password specified or else it can not log in:
[root@VicsVPS init.d]# mysql
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

However, using mysql cli on the system account "xerrao" will log into "xerrao@localhost" (i think)
