What is Zabbix?:

Zabbix is an open-source software tool to monitor IT infrastructure such as networks, servers, virtual machines, and cloud services. Zabbix collects and displays basic metrics.

Zabbix is designed primarily as an IT infrastructure monitoring tool. New features are generally released every six months to major versions and every 1.5 years to LTS versions.

Released under the terms of GNU General Public License version 2, Zabbix is free software that does not require a license to use any of its features. Even though Zabbix is open-source software, it is a closed development software product, developed by Zabbix LLC based in Riga, Latvia.

Early in its history, Zabbix was described as simple to set up compared to other monitoring solutions. However, later it was considered by some to need a significant amount of manual configuration. As an open-source product however Zabbix focuses on the usage of existing tools and functionality as well as proprietary solutions to achieve a scalable monitoring solution. (Source: Wikipedia)

Installing Linux Software Updates:

By using a ssh client, login to your Rocky Linux server as root user.

Set a FQDN (Fully Qualified Domain Name) for your network monitoring server by executing hostnamectl command.

# hostnamectl set-hostname

Refresh your yum cache as follows.

# dnf makecache --refresh
Rocky Linux 9 - BaseOS                          335 kB/s | 1.7 MB     00:05
Rocky Linux 9 - AppStream                       430 kB/s | 6.0 MB     00:14
Rocky Linux 9 - Extras                          1.7 kB/s | 6.6 kB     00:03
Metadata cache created.

Execute the following dnf command to install Linux software updates.

# dnf update -y

If the above command installs software updates related to Linux Kernel, then you should reboot your operating system with latest Kernel.

# reboot

After successful reboot, check the versions of Linux operating system and Kernel.

# cat /etc/rocky-release
Rocky Linux release 9.0 (Blue Onyx)

# uname -r


Installing MariaDB Server:

MariaDB 10.5 is available in standard yum repositories of Rocky Linux 9.0, which is supported by Zabbix 6.0.

Therefore, we are using MariaDB 10.5 in this server configuration guide. However, you can also install latest version of MariaDB Server.

# dnf install -y mariadb-server mariadb

Enable and start database Service.

# systemctl enable --now mariadb.service
Created symlink /etc/systemd/system/mysql.service → /usr/lib/systemd/system/mariadb.service.
Created symlink /etc/systemd/system/mysqld.service → /usr/lib/systemd/system/mariadb.service.
Created symlink /etc/systemd/system/ → /usr/lib/systemd/system/mariadb.service.

Initialize database instance and set a password for super admin.

# mariadb-secure-installation


In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
haven't set the root password yet, you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.

You already have your root account protected, so you can safely answer 'n'.

Switch to unix_socket authentication [Y/n] n
 ... skipping.

You already have your root account protected, so you can safely answer 'n'.

Change the root password? [Y/n] Y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] Y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] Y
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] Y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] Y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

Verify the database version as follows.

# mysql -V
mysql  Ver 15.1 Distrib 10.5.16-MariaDB, for Linux (x86_64) using  EditLine wrapper


Installing Zabbix Monitoring Tool:

Zabbix official website provides the installation/configuration steps to install various available versions of Zabbix on your preferred platform.

You are only required to select your platform, Zabbix version, database and web server.


Although the version 6.2 of Zabbix is available, but we prefer to use a LTS (Long Term Support) version, therefore, we are installing Zabbix 6.0.

Use rpm command to install Zabbix 6.0 official yum repository.

# rpm -Uvh
warning: /var/tmp/rpm-tmp.TnPIni: Header V4 RSA/SHA512 Signature, key ID 08efa7dd: NOKEY

Login to MariaDB by using mysql command and create a database to use as Zabbix back-end data store.

# mysql -u root -p
Enter password:

Zabbix software also shipped with a SQL script to create objects in it's back-end data store.

You can use zcat command to unzip and forward the output to mysql command for immediate execution.

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

Edit Zabbix configuration file by using vim text editor.

# vi /etc/zabbix/zabbix_server.conf

Locate and set the following directive in this file.


Enable and start Zabbix server and agent along with Apache and PHP services.

# systemctl enable --now zabbix-server zabbix-agent httpd php-fpm
Created symlink /etc/systemd/system/ → /usr/lib/systemd/system/zabbix-server.service.
