Zabbix is an open-source monitoring software designed for tracking the health and performance of servers, network devices, applications, and services. It provides a comprehensive set of monitoring features, such as real-time monitoring, alerting, and visualization, making it an ideal choice for IT infrastructure management.

In this guide, we will walk through the steps to set up Zabbix monitoring for your infrastructure. The process is broken down into simple steps, designed for beginners with no prior experience in setting up monitoring systems.

What is Zabbix?

Zabbix is a powerful enterprise-level monitoring platform that allows you to monitor the availability and performance of IT resources, including servers, virtual machines, network devices, and cloud-based infrastructure. It provides a centralized dashboard where you can view real-time and historical data about your infrastructure’s health.

Key Features of Zabbix:

• Real-time monitoring of servers, network devices, virtual machines, and databases.

• Alerting system that notifies you of potential issues or abnormal behavior.

• Customizable dashboards for visualizing your data and system status.

• Support for various data collection methods, such as SNMP, IPMI, and agent-based monitoring.

Prerequisites

Before you begin setting up Zabbix monitoring, ensure that you meet the following prerequisites:

• A server or virtual machine running a supported Linux distribution (Ubuntu, CentOS, RHEL, Debian, etc.).

• Sudo or root access to the server.

• A basic understanding of Linux terminal commands and system administration.

• A web server (Apache or Nginx) for serving the Zabbix frontend.

• A working database server (MySQL or PostgreSQL) for storing monitoring data.

Step 1: Install Zabbix Server

Install Zabbix Repository

The first step is to add the Zabbix repository to your server’s package manager so that you can easily install Zabbix.

For Ubuntu or Debian systems:

sudo apt update
sudo apt install -y wget
wget https://repo.zabbix.com/zabbix/5.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.0-1%2Bubuntu20.04_all.deb
sudo dpkg -i zabbix-release_5.0-1+ubuntu20.04_all.deb
sudo apt update

For CentOS or RHEL systems:

sudo yum install -y https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.x86_64.rpm
sudo yum clean all

Install Zabbix Server, Frontend, and Database

Once the repository is added, you can install the necessary Zabbix components. For example, to install the server and frontend:

On Ubuntu/Debian:

sudo apt install -y zabbix-server-mysql zabbix-frontend-php zabbix-agent

On CentOS/RHEL:

sudo yum install -y zabbix-server-mysql zabbix-web-mysql zabbix-agent

Install the Database Server

Zabbix requires a database to store monitoring data. You can use MySQL or PostgreSQL as the backend database. Here’s how to install MySQL:

On Ubuntu/Debian:

sudo apt install -y mysql-server

On CentOS/RHEL:

sudo yum install -y mariadb-server

Once MySQL is installed, start the MySQL service:

sudo systemctl start mysql

Create Zabbix Database and User

Next, you need to create a database for Zabbix to store its data. Log in to the MySQL/MariaDB command-line interface:

mysql -u root -p

Then create the Zabbix database and user:

CREATE DATABASE zabbix CHARACTER SET UTF8 COLLATE UTF8_BIN;
CREATE USER 'zabbix'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON zabbix.* TO 'zabbix'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Configure Zabbix Server

Import Database Schema

After setting up the database, import the Zabbix database schema. This can be done by running the following command:

sudo zabbix_server -n

Configure Zabbix Frontend

Set Up PHP for Zabbix Frontend

Ensure that PHP is installed and properly configured. Zabbix uses PHP to serve its web-based frontend. On Ubuntu/Debian:

sudo apt install -y php php-mbstring php-gd php-xml php-bcmath php-ldap

On CentOS/RHEL:

sudo yum install -y php php-mbstring php-gd php-xml php-bcmath php-ldap

Configure Web Server (Apache or Nginx)

Configure your web server to serve Zabbix frontend.

For Apache on Ubuntu/Debian:

sudo apt install -y apache2
sudo systemctl start apache2

For Nginx on Ubuntu/Debian, you would need to configure the /etc/nginx/sites-available/zabbix file to point to the Zabbix frontend location and ensure proper PHP handling.

Zabbix Frontend Configuration

Navigate to the Zabbix frontend in your browser (e.g., http://<server-ip>/zabbix) and follow the configuration wizard. During the setup:

• Provide the database details (database name, username, and password).

• Ensure that the server can connect to the database.

• Complete the setup by following the prompts in the wizard.

Start Zabbix Server and Agent

Start Zabbix Server

To start the Zabbix server, use the following command:

sudo systemctl start zabbix-server

Start Zabbix Agent

The Zabbix agent is responsible for collecting data from your monitored machines. Start the Zabbix agent with:

sudo systemctl start zabbix-agent

Access Zabbix Dashboard

Once the Zabbix server and agent are running, you can log in to the Zabbix frontend using your web browser. The default credentials are:

• Username: Admin

• Password: zabbix

The Zabbix dashboard provides an overview of your infrastructure, including monitored hosts, triggers, graphs, and more.

 Adding Hosts and Services for Monitoring

To monitor a server, you’ll need to add it as a “host” in the Zabbix dashboard. You can add a new host by going to Configuration > Hosts and clicking on Create Host. From there, you can specify the IP address, host group, and other settings.

Monitor Services

You can also configure Zabbix to monitor specific services like HTTP, MySQL, etc. This can be done under the Configuration > Templates section by linking a template to the host.
