# By default, MySQL does not allow root to run mysqladmin with no password.
# To get this script working, create /root/.my.cnf and put the following lines 
# in it (sans # signs)...
#
#[client]
#user = a_valid_mysql_user
#password = a_secret_password_1234
#host = localhost
#
# ...filling in your values for the user and password. Be sure to chmod .my.cnf
# to 600. You don't want other users to be able to read the username and 
# password.
