Now, let’s dive into the installation process.

Prerequisites

Before we begin, ensure that your server meets the following prerequisites:

• A Linux-based server (e.g., Ubuntu, CentOS, or Debian)
• Root access to the server
• A LAMP or LEMP stack (Linux, Apache/Nginx, MySQL/MariaDB, and PHP)
• At least 2 GB of RAM (Zabbix can be memory-intensive)
• Internet access to download Zabbix packages

In this guide, we will use Ubuntu 22.04 as the base operating system.

Step 1: Install the LAMP Stack

Before installing Zabbix, you must set up the LAMP stack (Linux, Apache, MySQL, and PHP). First, make sure your system is up-to-date:

sudo apt update
sudo apt upgrade

Now, install the LAMP stack:

sudo apt install apache2 mysql-server php php-mbstring php-gd php-xml php-bcmath php-ldap php-mysql -y

Once the installation is complete, start and enable MySQL and Apache services:

sudo systemctl start apache2
sudo systemctl enable apache2
sudo systemctl start mysql
sudo systemctl enable mysql

Verify that both services are running:

systemctl status apache2.service
systemctl status mysql.service

To secure the MySQL installation, run:

sudo mysql_secure_installation

Follow the prompts to secure your MySQL instance.

Step 2: Install and Configure Zabbix Server

1. Add the Zabbix Repository

First, download and install the Zabbix repository package:

wget https://repo.zabbix.com/zabbix/6.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_6.0-2+ubuntu22.04_all.deb
sudo dpkg -i zabbix-release_6.0-2+ubuntu22.04_all.deb
sudo apt update

2. Install Zabbix Server, Frontend, and Agent

Next, install the necessary Zabbix packages:

sudo apt install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-sql-scripts zabbix-agent

3. Create the Zabbix Database in MySQL

Access the MySQL CLI:

sudo mysql -uroot -p

Create the Zabbix database and user:

CREATE DATABASE zabbix CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;
CREATE USER 'zabbix'@'localhost' IDENTIFIED BY 'your_password';
GRANT ALL PRIVILEGES ON zabbix.* TO 'zabbix'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Make sure to replace 'your_password' with a secure password of your choice.

4. Import Zabbix’s Initial Schema

Import the Zabbix initial schema into the database:

zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix

5. Configure the Zabbix Server to Connect to MySQL

Edit the Zabbix server configuration file:

sudo vi /etc/zabbix/zabbix_server.conf

Find the DBPassword line and enter the password you created earlier.

Save and exit the file.

Step 3: Configure PHP for Zabbix Frontend

Next, we need to configure PHP settings for the Zabbix frontend.

Open the Zabbix Apache configuration file:

sudo vi /etc/zabbix/apache.conf

Add your preferred time zone:

php_value date.timezone Europe/London

Be sure to replace “Europe/London” with your server’s actual time zone.

Save the file and restart Apache:

sudo systemctl restart apache2

Step 4: Start and Enable Zabbix Server and Agent

Now, start the Zabbix server and agent, and enable them to start automatically on boot:

sudo systemctl start zabbix-server zabbix-agent
sudo systemctl enable zabbix-server zabbix-agent

Verify that the services are running:

sudo systemctl status zabbix-server zabbix-agent

Step 5: Configure Zabbix Frontend

You can now access the Zabbix frontend through a web browser. Open your browser and go to:

http://<your_server_ip>/zabbix

You will be prompted to input your database details, such as the Database Name, User, and Password. Enter the values you configured earlier.

Once the setup is complete, press Finish. You’ll be redirected to the Zabbix login page. Use the default credentials:

• Username: Admin
• Password: zabbix

Congratulations, your Zabbix installation is now complete, and you can begin monitoring your server.
