Tutorial on how to install Zabbix 5 LTS on Debian 10

Add Zabbix repository

Add Zabbix Repository with the following commands

$ sudo apt update && sudo apt install wget
$ wget https://repo.zabbix.com/zabbix/5.0/debian/pool/main/z/zabbix-release/zabbix-release_5.0-1+buster_all.deb
$ sudo apt install ./zabbix-release_5.0-1+buster_all.deb

Install Zabbix Server with Mariadb

Install Zabbix Server

$ sudo apt update
$ sudo apt install zabbix-server-mysql

Install Mariadb and secure the database

$ sudo apt install mariadb-server mariadb-client -y

#Set Root Password
$ sudo mysql

ALTER USER root@localhost IDENTIFIED VIA mysql_native_password;
SET PASSWORD = PASSWORD('P@ssw0rd!@#$');
flush privileges;
quit

#Secure MariaDB by enter "Y" for all options
$ sudo mysql_secure_installation

Change the root password? [Y/n] n
Remove anonymous users? [Y/n] y
Disallow root login remotely? [Y/n] y
Remove test database and access to it? [Y/n] y
Reload privilege tables now? [Y/n] y

# Start and enable Mariadb
$ sudo systemctl start mariadb
$ sudo systemctl enable mariadb

Verify Mariadb is installed successfully

$ sudo mariadb --version
mariadb  Ver 15.1 Distrib 10.3.27-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

Create Database for Zabbix

$ sudo mysql -u root -p

Create a new Zabbix Database (zabbixdb) and a new user (userzabbix). Replace SECURE_PASSWORD with your own password

CREATE DATABASE zabbixdb character set utf8 collate utf8_bin;
GRANT ALL PRIVILEGES ON zabbixdb.* TO userzabbix@localhost IDENTIFIED BY 'SECURE_PASSWORD';
FLUSH PRIVILEGES;
QUIT

Import initial schema and data

$ sudo zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -u userzabbix -p zabbixdb
Enter password: SECURE_PASSWORD

Configure Database Connection

$ sudo nano /etc/zabbix/zabbix_server.conf

DBHost=localhost          ##Uncomment this option
DBName=zabbixdb           ##Key in the database name you configured
DBUser=userzabbix         ##Key in the username you configured
DBPassword=SECURE_PASSWORD   ##Key in the password you configured

Install Zabix Frontend

Install Nginx and PHP

$ sudo apt install zabbix-frontend-php zabbix-nginx-conf

Verify Nginx & PHP version installed

$ sudo nginx -v
nginx version: nginx/1.14.2

$ sudo php -v

Configure PHP date.timezone parameter that Zabbix uses in its setup

date.timezone = Asia/Kuala_Lumpur

Restart PHP-FPM

Start Nginx Service and modify the Nginx configuration file created by Zabbix

$ sudo systemctl enable nginx
$ sudo systemctl start nginx

# Modify the Nginx Configuration File 
$ sudo nano /etc/nginx/conf.d/zabbix.conf

server {
listen 80;                          ## Uncomment this part
server_name debian.aventis.dev;     ## Uncomment this part too

Change the default Nginx file in Debian to listen on different port

$ sudo nano /etc/nginx/sites-available/default
server {
listen 82 default_server;        ## Change from 80 to 82
listen [::]:82 default_server;   ## Change from 80 to 82 as well

Change permission on Zabbix Root Folder and restart Nginx
