   shell> mysql -u root -p cacti < $(locate cacti.sql)
        HINT: If you get: "locate: fatal error: Could not find user database", run updatedb then retry.
   shell> mysql -u root -p cacti
   mysql> update user_auth set password=md5('admin') where username='admin'; <---may not be needed
   mysql> flush privileges;
   mysql> exit

   shell> use mysql
   mysql> GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'cactiuser';
   mysql> flush privileges;
   mysql> exit
