Step 1 – Update the system and install the required packages/dependencies

First of all, We need to update the system packages to the latest versions available

sudo apt update

Next, install packages/dependencies required by the Zabbix server

sudo apt install vim wget php-cgi php-common php-mbstring php-net-socket php-gd php-xml-util php-mysql php-bcmath php-imap php-snmp libapache2-mod-php libc6 -y

Step 2 – Configure PHP

PHP and PHP extensions installed, now Enable PHP CGI on the system

### If PHP 8 installed

sudo a2enconf php8.*-cgi

### If PHP 7 install

sudo a2enconf php7.*-cgi

Next, Using vim editor open and edit /etc/php/x/apache2/php.ini file (Replace x = PHP version installed on the system)

### PHP 8.1 installed on my system

sudo vim /etc/php/8.1/apache2/php.ini

  • Find and edit lines as below :
    • max_execution_time = 300
    • max_input_time = 300
    • memory_limit = 200M
    • post_max_size = 32M
    • upload_max_filesize = 16M
    • date.timezone = Asia/Ho_Chi_Minh ( replace Asia/Ho_Chi_Minh = Your-TimeZone)
  • After done, save and exit the file by pressing Esc Shift :x Enter

And don’t forget restart Apache service for the change to take effect:

sudo systemctl restart apache2

Step 3 – Create database for Zabbix Server

Login MariaDB/MySQL server

sudo mysql -uroot -p

Create a new database name called “zabbixdb

CREATE DATABASE zabbixdb character set utf8 collate utf8_bin;

Create a new database user called “zabbixuser” and set password is “zabbixPWD

CREATE USER zabbixuser@localhost IDENTIFIED BY ‘zabbixPWD’;

Grant all privileges on “zabbixdb” database to “zabbixuser” user

GRANT ALL ON zabbixdb.* TO zabbixuser@localhost;

Reload and exit




Step 4 – Add Zabbix APT Repositories

Access Zabbix Official Repository  choose the Zabbix version want to install and copy the linked repo correctly with your OS version

In this tutorials:

  • I choose Zabbix 6.0 LTS
  • My OS: Ubuntu 22.04 LTS

Next, download repository package file

wget link_in_step_above

### Example ( with Zabbix 6.0 LTS and Ubuntu 22.04 LTS )


Make sure it’s downloaded.



Now, install APT repositories

sudo dpkg -i Name_Of_Zabbix_Release_File

Next, Re-update system packages

sudo apt update


Step 5 – Install Zabbix Server

With the repository added and configured, Zabbix server packages can then be installed on your system

To install Zabbix Server and Zabbix Agent exucute the following command below:

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

After install success, We need start and enable Zabbix Server and Zabbix Agent services to auto-start on system restart or boot

sudo systemctl start zabbix-server

sudo systemctl start zabbix-agent

sudo systemctl enable zabbix-server

sudo systemctl enable zabbix-agent

Check status of Zabbix Server and Zabbix Agent services, make sure it’s running

sudo systemctl status zabbix-server

sudo systemctl status zabbix-agent


Step 6 – Configure Zabbix Server

First, find the place of default database

find /usr/share -name “server.sql.gz”

My path : /usr/share/zabbix-sql-scripts/mysql/server.sql.gz

Import the default schema and data to the database created in step 3

sudo zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql -uzabbixuser -p’zabbixPWD’ zabbixdb


Next, using VIM editor open /etc/zabbix/zabbix_server.conf file

sudo vim /etc/zabbix/zabbix_server.conf

  • Find and edit lines below:
    • DBName=zabbixdb
    • DBUser=zabbixuser
    • DBPassword=zabbixPWD
  • Save and exit file by press Esc Shift :x Enter

Now, Restart Zabbix-Server and Apache services for the change to take effect:

sudo systemctl restart zabbix-server

sudo systemctl restart apache2

Step 7 – Configure Firewall

Note : Skip this step if you don’t want to UFW firewall running on the system

Zabbix server to passive agent and responds to agent on 10050

Active agent to Zabbix server and Active agents requests zabbix on port 10051.

Therefore, We need to allow ports 10050 and 10051 through the firewall

sudo ufw enable     # Enable the firewall if it not yet running.

sudo ufw allow 10050   # Allow port 10050

sudo ufw allow 10051   # Allow port 10051

sudo ufw reload   # Reload UFW fireall

sudo ufw status   # Check status of UFW firewall


Step 8 – Setup Zabbix Server via web GUI
