How To Install Cacti Monitoring V1.2.3 on Ubuntu 18.04 LTS

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 creates graphs and populates 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 Monitoring on a Ubuntu 18.04 (Bionic Beaver) server.

Install Cacti Monitoring on Ubuntu 18.04 LTS

Step 1. First make sure that all your system packages are up-to-date Install Cacti Monitoring on Ubuntu 18

sudo apt-get update
sudo apt-get upgrade

Step 2. Install LAMP (Linux, Apache, MariaDB and PHP) server.

A Ubuntu 18.04 LAMP server is required. If you do not have LAMP installed, you can follow our guide here. Also install all required PHP modules:

apt-get install php7.1-cli php7.1-gd php7.1-opcache php7.1-mysql php7.1-json php7.1-mcrypt php7.1-xml php7.1-curl

Step 3. Configuring MariaDB for Cacti.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. you should read and below each steps carefully which will set root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB:


Configure it like this:

- Set root password? [Y/n] y
- Remove anonymous users? [Y/n] y
- Disallow root login remotely? [Y/n] y
- Remove test database and access to it? [Y/n] y
- Reload privilege tables now? [Y/n] y

Next we will need to log in to the MariaDB console and create a database for the Cacti. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for Cacti installation:

Ccreate database cacti;
GRANT ALL ON cacti.* TO [email protected] IDENTIFIED BY 'cactipassword';
flush privileges;

The newly created database user (cactiuser) should have access to the mysql.time_zone_name Table. To do that, import the mysql_test_data_timezone.sql to mysql database:

mysql -u root -p mysql < /usr/share/mysql/mysql_test_data_timezone.sql

Then, log in to Mariadb:

mysql -u root -p

Grant the permission to cactiuser:

GRANT SELECT ON mysql.time_zone_name TO [email protected];
flush privileges;

Step 4. Installing the Cacti packages.

Install SNMP and SNMP and RRDtools:

sudo apt-get install snmp snmpd snmp-mibs-downloader rrdtool

Now use the following command to install Cacti:

apt-get install cacti cacti-spine

During the installation process you will be prompted to configure Cacti with few options to select from available options. First of all Choose the web server that you wish to use for configure with Cacti like we are using Apache and then press ‘OK’ key to continue:


Now it will ask you for a webserver 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.

Once the installation process is complete, you will have to restart all services to reflect the changes made:

systemctl restart apache2.service
systemctl restart mysql.service
systemctl restart snmpd.service

Step 5. Accessing cacti.

Cacti will be available on HTTP port 80 by default. Open your favorite browser and navigate to or http://server-ip/cacti and complete the required the steps to finish the installation. You will get the “Cacti Installation Guide” on screen. Click on ‘Next’ button.
