2. select option 'apache2'
3. type your password of the database's administrative user (e.g.: root)
4. type your MySQL application password for cacti and retype in password confirmation (e.g.: root)
5. To complete the configuration process, open http://localhost/cacti in your favorite browser. 

In the installation type page, you can select if it's new install  or an upgrade. As we are going to install it for the first time, we will select New Install (which is selected by default) and click Next. The path settings page automatically determines the installed paths for RRDTool, PHP, SNMP and Cacti.log as well as the versions for Net-SNMP and RRDTool and then click Next.

In login screen, the username is admin and the default password is admin. After a successful login for the first time, the system will ask you to set a new password. Enter a new password and ensure you remember it. Without this password, you cannot administer the system!
