Update timezone in php configuration file /etc/php/PHP_VERSION/apache2/php.ini. Like below:

[Date]
; http://php.net/date.timezone
date.timezone = 'Asia/Kolkata'

Step 2 – Enable Required Apt Repository

Before installing Zabbix first configure Zabbix package repository in your system using following commands. Use commands as per your operating system.

## Ubuntu 18.04 LTS (Bionic):

wget https://repo.zabbix.com/zabbix/4.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_4.0-3+bionic_all.deb
sudo dpkg -i zabbix-release_4.0-3+bionic_all.deb

sudo apt-get install zabbix-server-mysql zabbix-frontend-php zabbix-agent

Step 4 – Create Database Schema

Now create a database schema for your Zabbix server. Login to your MySQL server using administrative privileges and use the following queries to create MySQL database and user for the Zabbix server.

mysql -u root -p

mysql> CREATE DATABASE zabbixdb character set utf8 collate utf8_bin;
mysql> CREATE USER 'zabbix'@'localhost' IDENTIFIED BY 'password';
mysql> GRANT ALL PRIVILEGES ON zabbixdb.* TO 'zabbix'@'localhost' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;

Also, load the Zabbix database schema to the database created above.

cd /usr/share/doc/zabbix-server-mysql
zcat create.sql.gz | mysql -u zabbix -p zabbixdb

Step 5 – Edit Zabbix Configuration File
