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

Step 2 – Configure Apt Repository

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

## For Debian 10:

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

## For Debian 9:

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

Step 3 – Install Zabbix Server

After adding the Zabbix repository in your system use following command to install Zabbix server. Here zabbix-server-mysql package includes Zabbix server with MySQL support. The zabbix-frontend-php package provides and web interface is written in PHP for the Zabbix server management

sudo apt-get update
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

Edit Zabbix server configuration file /etc/zabbix/zabbix_server.conf in your favorite text editor and update the following database configurations. This will be used by Zabbix server to connect to the database.

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

Step 6 – Restart Apache and Zabbix

Zabbix creates its own apache configuration file /etc/zabbix/apache.conf and make a link to Apache configuration directory. Let’s use the following command to restart Apache service.

sudo systemctl restart apache2.service
