mysql --user=root --password cacti < /usr/share/cacti/cacti.sql
Create Cacti user and set the right privileges to the database
[html]
# mysql --user=root --password
mysql> GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'cactipwd';
mysql> flush privileges;
mysql> exit
Configure Cacti with DB user and pwd
[html]
# vim /usr/share/cacti/include/config.php
$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cactiuser";
$database_password = "cactipwd";
$database_port = "3306";
$database_ssl = false;

# vim /etc/apache2/conf.d/cacti.conf
Alias /cacti /usr/share/cacti
<Directory /usr/share/cacti >
Options None

</Directory>
Restart the apache webserver

#/etc/init.d/apache2 restart

(use "admin" as the default username and password)
Add a line to your /etc/crontab file similar to
[html]
# vim /etc/cron.d/cacti
*/5 * * * * cactiuser php /usr/share/cacti/poller.php > /dev/null 2>&1
