Zabbix is an open-source, enterprise-class monitoring software designed to track the performance and availability of servers, network devices, and applications in real-time. Operating on a server-client model, it requires a central Zabbix server to collect data and Zabbix agents installed on the target systems to report metrics. Key features include real-time health monitoring (CPU, memory, disk usage), robust log file management, customizable alerting systems, and auto-discovery of network devices. It supports multiple databases like MySQL, PostgreSQL, and Oracle, offering both agentless and agent-based monitoring options.<\/p>\n\n\n\n\n\n\n\n
In this guide, we will walk through the complete process of installing and configuring Zabbix Server on Ubuntu 25.10. By following these beginner-friendly steps, you will have a fully functional monitoring system up and running on your server.<\/p>\n\n\n\n
Before proceeding, ensure your environment meets the following requirements:<\/p>\n\n\n\n
First, update your system package information to ensure you have the latest software lists.<\/p>\n\n\n\n
sudo apt update && sudo apt upgrade -y<\/pre>\n\n\n\nNext, install the necessary dependencies, including Apache web server, MySQL database server, PHP, and required PHP modules. <\/p>\n\n\n\n
sudo apt install apache2 mysql-server php php-mysql libapache2-mod-php -y<\/pre>\n\n\n\nStep 2: Install Zabbix Repository<\/h3>\n\n\n\n
Since the Zabbix package is not included in the default Ubuntu repository, you must add the official Zabbix repository. Download the Zabbix 7.2 DEB package using wget. <\/p>\n\n\n\n
wget https:\/\/repo.zabbix.com\/zabbix\/7.2\/release\/ubuntu\/pool\/main\/z\/zabbix-release\/zabbix-release_latest_7.2%2Bubuntu25.10_all.deb<\/pre>\n\n\n\nInstall the downloaded package to configure the repository:<\/p>\n\n\n\n
sudo dpkg -i .\/zabbix-release_latest_7.2+ubuntu25.10_all.deb<\/pre>\n\n\n\nStep 3: Install Zabbix Server, Frontend, and Agent<\/h3>\n\n\n\n
Refresh your package database to recognize the newly added Zabbix repository, then install the server, frontend, agent, and configuration scripts. <\/p>\n\n\n\n
sudo apt update\nsudo apt install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-sql-scripts zabbix-agent -y<\/pre>\n\n\n\nStep 4: Configure MySQL Database<\/h3>\n\n\n\n
You need to set up a database for Zabbix to store its data. Log in to the MySQL console: <\/p>\n\n\n\n
sudo mysql -u root<\/pre>\n\n\n\nExecute the following SQL commands to create a database, create a user, and grant the necessary permissions. Replace ‘password’ with a strong password of your choice. <\/p>\n\n\n\n
CREATE DATABASE zabbix CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;\nCREATE USER 'zabbix'@'localhost' IDENTIFIED BY 'password';\nGRANT ALL PRIVILEGES ON zabbix.* TO 'zabbix'@'localhost';\nset global log_bin_trust_function_creators = 1;\nFLUSH PRIVILEGES;\nEXIT;<\/pre>\n\n\n\nStep 5: Import Zabbix Database Schema<\/h3>\n\n\n\n
Now, import the initial schema and data into the database you just created. You will be prompted to enter the password you defined in the previous step. <\/p>\n\n\n\n
zcat \/usr\/share\/zabbix\/sql-scripts\/mysql\/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix<\/pre>\n\n\n\nNote: This process may take a moment. Do not interrupt it even if the screen appears to hang.<\/em><\/p>\n\n\n\n
Once the import is finished, disable the binary log trust function for better security: <\/p>\n\n\n\n
sudo mysql -u root<\/pre>\n\n\n\nset global log_bin_trust_function_creators = 0;\nEXIT;<\/pre>\n\n\n\nStep 6: Configure Zabbix Server<\/h3>\n\n\n\n
Edit the Zabbix server configuration file to connect it to your database. <\/p>\n\n\n\n
sudo nano \/etc\/zabbix\/zabbix_server.conf<\/pre>\n\n\n\nLocate the following lines, uncomment them (remove the #), and update the values to match your database setup: <\/p>\n\n\n\n
DBHost=localhost\nDBName=zabbix\nDBUser=zabbix\nDBPassword=password<\/pre>\n\n\n\nSave the file (Ctrl+O, Enter) and exit (Ctrl+X).<\/p>\n\n\n\n
Step 7: Start and Enable Services<\/h3>\n\n\n\n
Restart the Zabbix server, agent, and Apache services to apply changes, and enable them to start automatically on boot.<\/p>\n\n\n\n
sudo systemctl restart zabbix-server zabbix-agent apache2\nsudo systemctl enable zabbix-server zabbix-agent apache2<\/pre>\n\n\n\nYou can verify the status of the Zabbix server to ensure it is running correctly:<\/p>\n\n\n\n
systemctl status zabbix-server<\/pre>\n\n\n\nStep 8: Finalize Configuration via Web Interface<\/h3>\n\n\n\n
Open your web browser and navigate to http:\/\/your-server-ip\/zabbix. You will be greeted by the Zabbix installation wizard.<\/p>\n\n\n\n
\n
- Welcome:<\/strong> Select your preferred language and click “Next step”.<\/li>\n\n\n\n
- Prerequisites:<\/strong> Ensure all checks are green (OK), then click “Next step”.<\/li>\n\n\n\n
- DB Connection:<\/strong> Enter the database name (zabbix), user (zabbix), and the password you created earlier. Click “Next step”.<\/li>\n\n\n\n
- Settings:<\/strong> Set the Zabbix server name and select your time zone\/theme. Click “Next step”.<\/li>\n\n\n\n
- Summary:<\/strong> Review your settings and click “Next step” to finish the installation.<\/li>\n<\/ol>\n\n\n\n
Step 9: Post-Installation Security<\/h3>\n\n\n\n
After the wizard completes, you will be redirected to the login page.<\/p>\n\n\n\n
\n
- Default Username:<\/strong> Admin<\/li>\n\n\n\n
- Default Password:<\/strong> zabbix<\/li>\n<\/ul>\n\n\n\n
For security, immediately change the default password. Navigate to Users<\/strong> > Users<\/strong>, select the Admin<\/strong> user, click Change password<\/strong>, enter a secure password, and click Update<\/strong>.<\/p>\n\n\n\n
