Cacti: instalasi di Ubuntu
Before installing cacti you need to make sure to install all dependencies.
1 – Lamp server
First step is to install Lamp server (Apache, Mysql, PHP)
sudo apt-get install apache2 mysql-server php5 libapache2-mod-php5
2 – RRDtools
A useful open source tool for storage and retrieval of time series data.
sudo apt-get -y install rrdtool
3 – SNMP and SNMPd
If you want to monitor the localhost where cacti is installed you need to install and configure the service snmpd.
sudo apt-get -y install snmp snmpd
Now after installing all dependencies we start the installation of cacti.

If you want a faster way to poll servers for information than the default php script cmd.php, you need to install cacti-spine.
sudo apt-get -y install cacti cacti-spine
Popup message will appear like this just select OK and move on.
