How to Install Zabbix 5 on CentOS 7

Zabbix is an open source and the ultimate enterprise-level software designed for real-time monitoring of metrics collected from servers, virtual machines, network devices and applications.

Zabbix uses server-client architecture for various supported platforms including Linux, UNIX and Windows where the Zabbix agent, which is developed in C language, needs to be installed on respective servers to get monitored and collect data such as CPU, memory, disk and network interface usage from a device. It supports agentless monitoring for network devices via Simple Network Management Protocol (SNMP) or Intelligent Platform Management Interface (IPMI) generic monitoring protocols.

In this tutorial, we will explain how to install and configure Zabbix 5.0 on CentOS 7


  • Apache - Web Server
  • PHP
  • PHP Extensions
  • MariaDB Database

Update System

sudo yum update

Install Basic Packages

sudo yum install vim

Change SELinux mode to Permissive

Edit the /etc/selinux/config file as follows and reboot the system

sudo vim /etc/selinux/config

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.

# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.


Install Apache

sudo yum install httpd

Start and enable the Apache services at boot time.

sudo systemctl start httpd
sudo systemctl enable httpd

Install MariaDB Database

By default CentOS 7 base repository provides MariaDB 5.5 version, which will work for osTicket application. But in this tutorial, we will install the latest version of MariaDB 10.4

Create repo for MariaDB 10.4

sudo vim /etc/yum.repos.d/MariaDB.repo

name = MariaDB
baseurl =

Install MariaDB and its dependencies

sudo yum install MariaDB-server

Start and enable the MariaDB Server services at boot time.

sudo systemctl start mariadb
sudo systemctl enable mariadb

Configure MariaDB

sudo mysql_secure_installation

Create Database for Zabbix Server

sudo mysql -u root -p

create database zabbixdb character set UTF8 collate utf8_bin;
create user 'zabbixuser'@'localhost' identified BY 'Linuxyogi@123';
grant all privileges on zabbixdb.* to zabbixuser@localhost ;
flush privileges;

Install Zabbix Server and dependencies

Add Zabbix repository. Use the latest download URL from the official website.

sudo yum install

Install Zabbix packages

sudo yum install zabbix-server-mysql zabbix-agent zabbix-get

Install yum-utils, it is a collection of tools and programs for managing yum repositories, installing debug packages, source packages, extended information from repositories and administration. Use the yum-config-manager program to enable Zabbix Frontend repository.

sudo yum install yum-utils
sudo yum-config-manager --enable zabbix-frontend

Install remaining Zabbix packages including PHP 7.2 and its dependencies.

sudo yum -y install centos-release-scl
sudo yum -y install zabbix-web-mysql-scl zabbix-apache-conf-scl

Import initial schema to database.

sudo zcat /usr/share/doc/zabbix-server-mysql-5.0.5/create.sql.gz | mysql -uzabbixuser -p zabbixdb

 Configure Zabbix Database configuration file.


Uncomment DBPassword=

Configure the php.ini and Zabbix frontend timezone

sudo vim /etc/php.ini

Uncomment date.timezone =
date.timezone = Asia/Kolkata

sudo vim /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf

'php_value[date.timezone] =

Restart and enable the services at boot level.

sudo systemctl restart zabbix-server zabbix-agent httpd rh-php72-php-fpm
sudo systemctl enable zabbix-server zabbix-agent httpd rh-php72-php-fpm

Allow TCP ports 10051 and 10050 from Firewall for Zabbix agent to communicate with Zabbix Server and TCP 80 port for Zabbix Server Dashboard access.

sudo firewall-cmd --add-port={10051/tcp,10050/tcp,80/tcp} --permanent
sudo firewall-cmd --reload
