In this tutorial, we will show you how to install and configuration Cacti Monitoring on Ubuntu 15.04. For those of you who didn’t know, Cacti is an open-source, web-based network monitoring and graphing tool designed as a front-end application for the open-source, industry-standard data logging tool RRDtool. It is used by IT businesses and stores all of the necessary information about bandwidth, hard disk usage, CPU usage, load average, RAM statistics, etc in a MySQL database. Cacti create graphs and populate them with data. It offers SNMP support, 3rd party templates, and plugins and has built-in user authentications and user permission features.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Cacti on an Ubuntu 15.04 server.
Install Cacti Monitoring on Ubuntu 15.04
Step 1. First, make sure that all your system packages are up-to-date by running these following apt-get commands in the terminal.
sudo apt-get update sudo apt-get upgrade
Step 2. Install LAMP (Linux, Apache, MariaDB, PHP) server.
A Ubuntu 15.04 LAMP server is required. If you do not have LAMP installed, you can follow our guide here. Also install all PHP required modules:
apt-get install php5 php5-mysql php5-snmp snmp php5-gd libapache2-mod-php5
Step 3. Installing the Cacti packages.
Install SNMP and SNMP and RRDtools:
apt-get install snmp snmpd rrdtool
Now use the following command to install Cacti:
apt-get install cacti-spine
A popup message will appear like this just select OK and move on.
Now it will ask you for a web server that you will use it, we choose Apache2 since that’s what we installed in the dependencies.
Next, it will ask to configure the Cacti database, select Yes.
Now it will ask for your root password of MySQL/MariaDB database.
Before we start the web configuration part, we need to start the snmpd service.
sudo /etc/init.d/snmpd start
Step 3. Accessing cacti.
Cacti will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://yourdomain.com/cacti or http://server-ip/cacti and complete the required steps to finish the installation. You will get the “Cacti Installation Guide” on screen. Click on the ‘Next’ button.
On the next screen, you will get a drop-down button. Because of this fresh installation select ‘New Install’ and click the ‘Next’ button.
Cacti will now check for the packages it needs to run properly. Make sure all the checks appear with an “OK” status and then click Finish.
The next page is the login page. The first time you log into Cacti, use admin as username and password.
