How do we Install Zabbix on Debian 10

Posted by

Zabbix is a free, open-source, popular and feature-rich IT infrastructure monitoring software developed using PHP language. It is used to monitor networks, servers, applications, services as well as cloud resources. It also supports monitoring of storage devices, databases, virtual machines, telephony, IT security resources, and much more.

For developers, Zabbix ships with an API that provides access to almost all functions available in Zabbix. It supports easy two-way integration with any software. You can also use the API to integrate Zabbix functions into third-party software.


  1. Debian 10 Minimal installation

This tutorial shows how to install and configure the latest release of Zabbix 4.2 Server on Debian 10 with MySQL database to keep data, PHP and Apache Web Server as the mainly web interface.

Step 1: Installing Apache Web Server and PHP Packages

1. To install Zabbix, first you need to install Apache and PHP along with some required PHP modules as follows.

# apt install apache2 php php-mysql php-mysqlnd php-ldap php-bcmath php-mbstring php-gd php-pdo php-xml libapache2-mod-php

2. In the installation process, the installer triggers systemd to automatically start Apache service, and it also enables it to automatically start at system boot. You can check if it is up and running using the systemctl command.

# systemctl status apache2

The following are some useful systemctl command for managing the Apache services under systemd.

# systemctl start apache2
# systemctl stop apache2
# systemctl restart apache2

Step 2: Install MariaDB Server and Client

3. To store data, Zabbix requires a database management system. It supports MySQL by default but for this guide, we will install MariaDB as a drop-in replacement for MySQL.

# apt install mariadb-server mariadb-client

4. When the installation is complete, the MariaDB service is auto-started and enabled to automatically start at system startup. To check if it is up and running, use the following command.

# systemctl status mariadb
Checkk MariaDB Status in Debian

5. Next, you need to secure your MariaDB server database installation. The installed package ships with a script which you need to run and follow the security recommendations.

# mysql_secure_installation

It will ask you to determine actions to removing anonymous users, disabling root login remotely, removing test database and access to it, and applying all changes.

6. Once the database server is secured, you need to create a database for Zabbix. First, log in to the database to gain access to the MariaDB shell as follows.

# mysql -u root -p

7. Then issues the following SQL commands to create the required database (do not forget to set a secure password).

MariaDB [(none)]> create database zabbix character set utf8 collate utf8_bin;
MariaDB [(none)]> grant all privileges on zabbix.* to zabbix@localhost identified by 'admin@monit1';
MariaDB [(none)]> quit;

Step 3: Installing and Configuring Zabbix Server

8. To install Zabbix, you need to enable the Zabbix Official Repository which contains the Its packages, as follows.

# wget
# dpkg -i zabbix-release_4.2-2+buster_all.deb
# apt update 

9. Now install the Zabbix server, web frontend, agent packages using the following command.

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

10. If the package installation is successful, next, import the initial schema and data into the Its database which you created in the previous step.

# zcat /usr/share/doc/zabbix-server-mysql/create.sql.gz | mysql -u zabbix -p zabbix

11. Next, configure the Zabbix server daemon to use the database you created for it by editing the file /etc/zabbix/zabbix_server.conf.

# vim /etc/zabbix/zabbix_server.conf

Look for the following configuration options and update their values to reflect your database settings. Note that you need to uncomment any option(s) that are commented out and set their correct values.

Then save the new changes in the file and exit it.

12. You should also set up PHP to work correctly with the Its frontend by defining your timezone in the /etc/zabbix/apache.conf file.

# vim /etc/zabbix/apache.conf

Find the configuration section for your PHP version, for example, PHP 7.x. Then uncomment the following line (by removing the “#” character at the start) to enable timezone for your server as shown in the screenshot.

php_value date.timezone Africa/Kampala
Configure PHP Timezone

Save the changes and close the file.

13. Now restart the Apache server to apply recent changes.

# systemctl restart apache2

14. With all the perfect environment setup, you can now start the Zabbix server and agent processes, enable them to auto-start at system boot as shown.

# systemctl start zabbix-server zabbix-agent
# systemctl enable zabbix-server zabbix-agent
Start Zabbix Server and Agent

15. Then make sure to check the status of Its server using the following command.

# systemctl status zabbix-server
Check Zabbix Status

16. Also, ensure that the zabbix agent process is up and running by checking its status as shown. Remember the agent you have started is running on and monitoring the localhost. If you want to monitor remote servers, install and configure agents on them (refer to related articles at the end of the guide).

# systemctl status zabbix-agent
Check Zabbix Agent Status

17. Before you can access the Zabbix web frontend as shown in the next section, if you have the UFW firewall service running, you need to open the port 80(HTTP) and 443(HTTPS) to allows traffic to the Apache server.

# ufw allow 80/tcp
# ufw allow 443/tcp
# ufw reload

Step 4: Installing and Configuring Zabbix Web Frontend Interface

18. Before you can start using the It web frontend for monitoring, you need to configure and set it up via a web installer. To access the installer, open a web browser and point it to the following URL.


19. Once you click go, or press Enter, you will land on Welcome page as shown in the following screenshot. Click Next step to start the setup process.

20. The installer will then check the pre-requisites as shown in the screenshot, if all required PHP modules and configuration options are OK (scroll down to view more requirements), click Next step to proceed.

21. Next, enter the database connection settings for the Zabbix frontend to link to the database. Choose the database type (which should be MySQL), provide the database host, database port, database name, and database user and the user’s password as shown in the screenshot.

22. Next, enter the Its server details (hostname or host IP address and port number of the hosting server). Optionally, set a name for the installation.

23. Now the installer should show you the pre-installation summary page. If all is fine, click Next step to complete the setup.

24. Now click Finish, and you should be re-directed to the login page as shown in the next screenshot.

26. Once you have logged on, you will see the Monitoring section Dashboard. The Global view will display a sample of System information, problems by severity, problems, local time and more, as shown in the screenshot.

27. As an important step, you need to change the default administrator account password. To do that, go to Administration ==> Users.

From the list users, under Alias, click on Admin to open the user’s details. In the user details page, look for the Password field and click Change password. Then set a secure password and confirm it. And click Update to save the password.
