Ao instalar o mysql-server e o mysql-administrator, ao tentar conectar no banco era retornado o seguinte erro:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: N O)

E, para resolver esse erro fiz o seguinte:

Parei o mysql:

# /etc/init.d/mysql stop
Stopping MySQL database server: mysqld.

Iniciei o MySQL sem senha:

# mysqld_safe --skip-grant-tables &
[1] 4131
Starting mysqld daemon with databases from /var/lib/mysql
mysqld_safe[4193]: started

Conectei ao MySQL usando:

$ mysql client - mysql -u root
