         mysql cacti < /var/www/cacti/cacti.sql

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

[3.] vi /var/www/cacti/include/config.php

/* make sure these values refect your actual database/host/user/password */
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "cactiuser";
$database_port = "3306";

[4.] 如果是用tarball安裝時，需加入排程

*/5 * * * * cactiuser php /var/www/html/cacti/poller.php > /dev/null 2>&1

            mysql> update user_auth set password=md5('admin') where username='admin';
