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;

Create Cacti Apache configuration file

[html]

# vim /etc/apache2/conf.d/cacti.conf

Alias /cacti /usr/share/cacti

Options None

Allow from 127.0.0.1

Allow from All

</Directory>

Restart the apache webserver

[html]

#/etc/init.d/apache2 restart

Finally We can log into cacti website:

http://IP/cacti

(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

Configure SNMP

For easy to let cacti to access and monitor other hosts we use below simple way to configure snmp file.

[html]

# vim /etc/snmp/snmpd.conf

rocommunity public

syslocation "Your Location"

syscontact admin@domain.com

Try to add host into Cacti and see the result. Good luck!
