How To Install Zabbix 5.0 On Ubuntu 20.04

Zabbix is an open-source enterprise-class monitoring tool for servers, network devices, and applications. Zabbix uses the agent installed on remote hosts to collect the system metrics. It can also monitor standard services such as SMTP or HTTP services without having a client on the remote host.

Additionally, Zabbix supports host monitoring via SNMP, TCP, and ICMP checks, as well as over IPMI, JMX, SSH, and telnet. Zabbix can send you with real-time alert notification via SMS, E-mail, alert scripts, and webhook.

Zabbix is released under the GPL license v2.

Here, we will see how to install Zabbix Server Ubuntu 20.04.

Install Zabbix 5.0 On Ubuntu 20.04

System Requirements

Zabbix requires at least 128MB of RAM and 256MB of HDD space. However, the amount of memory or disk depends on the number of hosts and parameters are being monitored.

Configure Zabbix repository

Zabbix LLC provides Zabbix packages over an official repository for Ubuntu 20.04. So, set up the Zabbix repository on the system.

wget https://repo.zabbix.com/zabbix/5.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.0-1+focal_all.deb

sudo dpkg -i zabbix-release_5.0-1+focal_all.deb

Install Zabbix Server

Use the apt command to install the Zabbix server along with MariaDB on your system.

sudo apt update

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

Timezone

Edit the Zabbix configuration file to update it with the correct timezone based on your location.

sudo nano /etc/zabbix/apache.conf

Update the below line with your timezone. Visit the link for supported timezones.

<IfModule mod_php7.c>

        ...
        ...

        php_value date.timezone America/New_York

        ...
        ...

</IfModule>

Create Database

Login to the MariaDB server and create a database for the Zabbix installation.

sudo mysql -u root -p

Here, I assume the following:

DBName: zabbix

DBUser: zabbixuser

DBPassword: password

create database zabbix character set utf8 collate utf8_bin;

grant all privileges on zabbix.* to zabbixuser@localhost identified by 'password';

quit;

Import the initial schema into the created database.

cd /usr/share/doc/zabbix-server-mysql

zcat create.sql.gz | mysql -u zabbixuser -p zabbix

Update Zabbix Configuration

Edit the zabbix_server.conf file to update the database details.

sudo nano /etc/zabbix/zabbix_server.conf

Ensure the database details are entered properly.

DBHost=localhost
DBName=zabbix
DBUser=zabbixuser
DBPassword=password

Restart all the services.

sudo systemctl restart zabbix-server zabbix-agent apache2

Enable the services to start automatically on system reboot.

sudo systemctl enable zabbix-server zabbix-agent apache2
