    Zabbix Install on Ubuntu 20.04 – Installation Steps

    At the time of installation latest version of Zabbix is version 5.4. To run Zabbix you need Apache, MySQL, and PHP installed on the server. I assume, you already installed the LAMP stack on your Ubuntu server. If not, follow this LAMP installation guide for installation steps.

    Now, let’s install Zabbix monitoring tool on Ubuntu 20.04 step-by-step.

    Step 1: Install Zabbix Monitoring Tool on Ubuntu 20.04

    First, login to the server. I am using AWS EC2 Ubuntu instance for the installation.

    $ ssh -i Download/zabbix.pem [email protected]

    Now, you have to options to download the zabbix on Ubuntu.

    Option 1: You can install Zabbix Monitoring Tool on Ubuntu 20.04 from the ubuntu package manager. But this is not recommended as most of the outdated versions.

    Option 2: Download the Zabbix from the official website. You can build Zabbix packages download links by choosing the Zabbix version, OS, OS version, database, and webserver.

    Zabbix downloading packages build

    Option 2 is recommended way to install Zabbix. Now copy the download link and run on command line.

    $ wget https://repo.zabbix.com/zabbix/5.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.4-1+ubuntu20.04_all.deb
    $ sudo dpkg -i zabbix-release_5.4-1+ubuntu20.04_all.deb

    Output will be something like this

    Selecting previously unselected package zabbix-release.
    (Reading database ... 89746 files and directories currently installed.)
    Preparing to unpack zabbix-release_5.4-1+ubuntu20.04_all.deb ...
    Unpacking zabbix-release (1:5.4-1+ubuntu20.04) ...
    Setting up zabbix-release (1:5.4-1+ubuntu20.04) ...

    Now, update the package manager to install Zabbix packages

    $ sudo apt update

    After updating the Ubuntu package manager, now install Zabbix frontend, Zabbix agent and other packages by following command.

    $ sudo apt install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-agent

    Step 2: Create Database and Import Zabbix Database Scheme

    Login to MySQL dashboard and create a database for Zabbix.

    $ mysql -u root -p
    mysql> CREATE DATABASE zabbix_db character set utf8 collate utf8_bin;

    After creating database for the Zabbix, import Zabbix database scheme by following command.

    zcat /usr/share/doc/zabbix-sql-scripts/mysql/create.sql.gz | mysql -uroot -p zabbix_db

    Your Zabbix database scheme is successfully imported to zabbix_db.

    Now, in order to use the database with Zabbix server, you have to edit the Zabbix server configuration file.

    $ sudo vi /etc/zabbix/zabbix_server.conf

    Find the DBUser, DBName and DBpassword to change with your values.

    DBName=zabbix
    DBUser=root
    DBPass=xxxxx

    Step 3: Configuring PHP for Zabbix Frontend

    The Zabbix Frontend is written in PHP and requires some special PHP server settings. During Zabbix installation an apache configuration file generated, you can find the file under the directory /etc/zabbix. Open configuration file by the following command.

    $ sudo vi /etc/zabbix/apache.conf

    Output should look like

    <IfModule mod_php7.c>
            php_value max_execution_time 300
            php_value memory_limit 128M
            php_value post_max_size 16M
            php_value upload_max_filesize 2M
            php_value max_input_time 300
            php_value max_input_vars 10000
            php_value always_populate_raw_post_data -1
            # php_value date.timezone Europe/Riga
    </IfModule>

    Uncomment the time zone line and change it to your time zone.

    Now, restart Apache server . Use following command to restart Apache.

    $ sudo systemctl restart apache2

    Start Zabbix server using following command.

    $ sudo systemctl start zabbix-server

    Check the Zabbix server status, to make sure it started.

    $ sudo systemctl status zabbix-server

    Output should look like

    zabbix server status

    Finally, enable the server to start at boot time by following command.

    $ sudo systemctl enable zabbix-server

    Step 4: Install and Configure Zabbix Frontend

    Open the Zabbix frontend installation page using your favorite browser such as chrome. The address will be your server IP/zabbix.

    18.116.41.244/zabbix

    On the first screen, you will see a welcome message with the option to select the default language. Click Next step to continue. Now, the installer will show you the prerequisites of the server. Scroll down to check, if all the required values are set correctly or not, and then proceed to the next step.
