Zabbix 6.2 – instructions for installation in 5 minutes
In this article, we will show you how to install and configure Zabbix 6.2 with a PostgreSQL 14 database on Rocky Linux 8 in five minutes.
What is waiting for us?
- PostgreSQL installation
- Installation of Zabbix server and its components
- Database initialization
- TimescaleDB installation
- Zabbix server configuration
- Zabbix frontendu configuration
- Configuration of Zabbix reporting
Before we start
For the purposes of this example, we will first switch SELinux mode to Permissive.
setenforce 0
PostgreSQL installation
First, install the official PostgreSQL repositories and disable the default system PostgeSQL repositories.
dnf install -y https://download.postgresql.org/pub/repos/yum/reporpms/EL-8-x86_64/pgdg-redhat-repo-latest.noarch.rpm
dnf -qy module disable postgresql
And now install PostgreSQL, in this case it will be PostgreSQL 14.
dnf install -y postgresql14-server
Now all that’s left is to initialize the database and set up automatic startup.
/usr/pgsql-14/bin/postgresql-14-setup initdb
systemctl enable postgresql-14 --now
Installation of Zabbix server and its components
We have installed the database, so let us move on to installing the Zabbix server and its components.
Add the Zabbix repositories and clear the installation cache.
rpm -Uvh https://repo.zabbix.com/zabbix/6.2/rhel/8/x86_64/zabbix-release-6.2-3.el8.noarch.rpm
dnf clean all
Switch default PHP to version 7.4
dnf module enable php:7.4 -y
And then install all of the necessary Zabbix components.
dnf install zabbix-server-pgsql zabbix-web-pgsql zabbix-apache-conf zabbix-sql-scripts zabbix-agent2 zabbix-web-service
Finally, enable all the necessary ports on the firewall.
firewall-cmd --permanent --add-service=http
firewall-cmd --permanent --add-port=10051/tcp
firewall-cmd --reload
Database initialization
In the next step, create a user for Zabbix in the database. You will be prompted to enter a password.
cd /tmp
sudo -u postgres createuser --pwprompt zabbix
Next, create a database and import the default schema and data.
You will be asked to enter your password again. Use the password created in the previous step.
Attention! In older versions of Zabbix, this path is different, namely /usr/share/doc/zabbix-sql-scripts/
!
sudo -u postgres createdb -O zabbix zabbix
zcat /usr/share/zabbix-sql-scripts/postgresql/server.sql.gz | sudo -u zabbix psql zabbix
TimescaleDB installation
Now let’s get down to installing TimescaleDB.
First add a repository.
tee /etc/yum.repos.d/timescale_timescaledb.repo <<EOL
[timescale_timescaledb]
name=timescale_timescaledb
baseurl=https://packagecloud.io/timescale/timescaledb/el/$(rpm -E %{rhel})/\$basearch
repo_gpgcheck=1
gpgcheck=0
enabled=1
gpgkey=https://packagecloud.io/timescale/timescaledb/gpgkey
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt
metadata_expire=300
EOL
Next, install TimescaleDB.
dnf install timescaledb-2-postgresql-14-2.7.0 timescaledb-2-loader-postgresql-14-2.7.0 -y
Now open the PostgreSQL configuration file /var/lib/pgsql/14/data/postgresql.conf and find this line:
# shared_preload_libraries = ''
Add this line below:
shared_preload_libraries = 'timescaledb'
Save the file and restart the database.
systemctl restart postgresql-14.service
All that remains is to activate TimescaleDB.
Attention! In older versions of Zabbix, this path is different, that is /usr/share/doc/zabbix-sql-scripts/
!
echo "CREATE EXTENSION IF NOT EXISTS timescaledb CASCADE;" | sudo -u postgres psql zabbix
cat /usr/share/zabbix-sql-scripts/postgresql/timescaledb.sql | sudo -u zabbix psql zabbix
Zabbix server configuration
Open the Zabbix server configuration file
nano /etc/zabbix/zabbix_server.conf
and adjust the individual parameters according to the following example.
DBPassword=<heslo do databáze>
StartReportWriters=1
WebServiceURL=http://localhost:10053/report
HANodeName=initMAX
Finally, install Czech and Slovak language packs (optional), restart all related services and set them for automatic startup.
dnf install glibc-langpack-cs.x86_64 glibc-langpack-sk.x86_64
systemctl restart zabbix-server zabbix-web-service zabbix-agent2 httpd php-fpm
systemctl enable zabbix-server zabbix-web-service zabbix-agent2 httpd php-fpm
less /var/log/zabbix/zabbix_server.log
Zabbix frontend configuration
In the browser window, open the URL on which Zabbix is running and the installation wizard will welcome us. For example http://192.168.0.50/zabbix
.
By clicking on the Next step button, move to the minimum requirements check page.

Everything is fine, so you can click on the Next step button and move to the next phase with the database connection settings.

On this page, fill in the Password field, nothing else needs to be changed. When finished, click on Next step button.

Fill in the basic settings, i.e. server name and time zone, and then click Next step to continue to the configuration summary.

Check the entered values and click Next step to complete the installation.

Click Finish to go to the login screen.

Log in and can start using Zabbix 6.2 (Admin/zabbix).

After logging in, you’re welcomed with all the new Zabbix 6.2!

Configuration of Zabbix reporting
To use the reporting functions, you must first install Google Chrome.
First, download and install the installation package.
wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm
dnf localinstall google-chrome-stable_current_x86_64.rpm
Next, adjust the “Frontend URL” parameter in the configuration of the Zabbix frontend to the current value, this setting can be found in the following path in the menu:
Administration -> General -> Other
You can see an example of the settings in the image below.
