Zabbix is a strong monitoring tool for network monitor written by php mysql. Debian 12 is newly release, so I want to show how to install zabbix server 7.0 on debian 12 server.

####################################
Operating System: Debian 12
IP Address  : 10.66.10.12
RAM   : 2GB
Disk   : 50GB
Service  : Zabbix
Host Name : zabbix.technologyrss.local

Step #01: Ensure Update and upgrade using below command.

root@zabbix:~# lsb_release -a &&  ip r
root@zabbix:~# apt update && apt -y upgrade
root@zabbix:~# apt install -y apt-transport-https lsb-release ca-certificates

Step #02: Install php on debian 12

root@zabbix:~# add-apt-repository ppa:ondrej/php
root@zabbix:~# apt update
root@zabbix:~# apt install -y php php-mysql php-common php-cli php-common php-json php-opcache php-readline php-mbstring php-gd php-dom php-zip php-curl

Check php is working. Create php infi file.

root@zabbix:~# nano /var/www/html/info.php

Insert below line into info.php file.

<?php phpinfo() ;?>

Now going to browser and type your server ip address:

http://10.66.10.12/info.php

Step #03: Install database server mariadb.

root@zabbix:~# apt install -y mariadb-server

When installing running then type mysql root password and remember it for use next time.

Step #04: Download and install zabbix main package.

root@zabbix:~# wget https://repo.zabbix.com/zabbix/6.5/debian/pool/main/z/zabbix-release/zabbix-release_6.5-1+debian12_all.deb
root@zabbix:~# dpkg -i zabbix-release_6.5-1+debian12_all.deb
root@zabbix:~# apt update
root@zabbix:~# apt install -y zabbix-server-mysql zabbix-frontend-php zabbix-nginx-conf zabbix-sql-scripts zabbix-agent

Step #05: Login mysql terminal for create database and user password.

root@zabbix:~# mysql -u root -p

Then type mysql root password. Then run below command from mysql terminal

SELECT user,authentication_string,plugin,host FROM mysql.user;
ALTER USER root@localhost IDENTIFIED VIA mysql_native_password;
SET PASSWORD = PASSWORD('P@ssw0rd0@123');
SELECT user,authentication_string,plugin,host FROM mysql.user;
create database zabbix_db character set utf8mb4 collate utf8mb4_bin;
create user zabbix_user@localhost identified by 'P@ssw0rd0@123';
grant all privileges on zabbix_db.* to zabbix_user@localhost;
set global log_bin_trust_function_creators = 1;
flush privileges;
\q

Step #06: Export zabbix default database into my created database.

root@zabbix:~# zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix_user -p zabbix_db

Then type my created zabbix_user password, then wait ….

Again going to mysql terminal for change global settings.

root@zabbix:~# mysql -uroot -p

Run below command from mysql terminal.

set global log_bin_trust_function_creators = 0;
flush privileges;
\q

Step #07: Configure zabbix server conf file.

DBName=zabbix_db
DBUser=zabbix_user
DBPassword=P@ssw0rd0@123

Then save and exit.

Setup nginx web server.

root@zabbix:~# nano /etc/zabbix/nginx.conf

Remove # from below two lines and type your server ip address or domain name.

listen 80;
server_name 10.66.10.12;

Note: If your server have multiple web server running so must be stop it first.

root@zabbix:~# service apache2 stop

Now restart service using below command.

root@zabbix:~# systemctl restart zabbix-server zabbix-agent nginx php8.2-fpm
root@zabbix:~# systemctl enable zabbix-server zabbix-agent nginx php8.2-fpm

Done! All terminal installation. Now going to web browser and process installation.
