Zabbix Installation On RHEL8: Single Host Installation

-

 A "single host installation" refers to installing and running a software application on a single physical or virtual machine. In this, all software components, such as the database, application server, web server, and other necessary services, are hosted on one machine in this setup.

Installation Steps:

    Step 1: Install and Configure the Zabbix Repository

    rpm -Uvh https://repo.zabbix.com/zabbix/6.0/rhel/8/x86_64/zabbix-release-6.0-4.el8.noarch.rpm

    dnf clean all


    Step 2: Install Zabbix Server, Frontend, and Agent

    dnf install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-sql-scripts zabbix-selinux-policy zabbix-agent


    Step 3: Install and Configure the Database

    yum install mysql-server -y

    mysql -u root -p

mysql> create database zabbix character set utf8mb4 collate utf8mb4_bin;

mysql> create user zabbix@localhost identified by 'zabbix';

mysql> grant all privileges on zabbix.* to zabbix@localhost;

mysql> set global log_bin_trust_function_creators = 1;


    mysql> quit;


    Step 4: Import Initial Schema and Data

    zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix


    Step 5: Configure Zabbix Server

    vi /etc/zabbix/zabbix_server.conf

    DBPassword=zabbix (same as using while creating the user in mysql)


    Step 6: Disable the SELINUX

    vi /etc/selinux/config
    
SELINUX=disabled


    Step 7: Disable the firewall
    systemctl stop firewalld
    
systemctl disable firewalld


    Step 8: Start Zabbix Server and Agent Processes
    systemctl restart zabbix-server zabbix-agent httpd php-fpm
    
systemctl enable zabbix-server zabbix-agent httpd php-fpm mysqld



    Step 9: Configure Zabbix Frontend
    Open your web browser and navigate to the Zabbix frontend setup

    http://your_server_ip/zabbix

Ensure the firewall is configured to allow the TCP/UDP port 514 or disable the firewall service. 6. Ensure that SELinux is disable if not disable it Check the status of SELinux sestatus Disa...

      Zabbix built-in HA Vs Pacemaker/corosync

      -
       Built-in HA in Zabbix Since Zabbix 7.0, Zabbix Server has built-in high availability (HA) support. This means: You can run multiple Zabbix server nodes. Only one is active at a time. The others are standby and can take over if the active one fails. Failover is handled internally by Zabbix, using database coordination (it stores node status in the DB). So why Pacemaker and Corosync then? You don’t need Pacemaker + Corosync for the Zabbix Server itself anymore if you’re using built-in HA. However, there are still scenarios where Pacemaker/Corosync may be useful: When to Use Pacemaker/Corosync Database Failover: Zabbix’s built-in HA does not handle database HA. Pacemaker/Corosync can manage MySQL/MariaDB/PostgreSQL clusters with automatic failover.        2. Frontend High Availability: Zabbix frontend (Apache/Nginx + PHP) does not have built-in HA. You can use Pacemaker/Corosync (or HAProxy/Keepalived) to manage failover of frontend nodes and virtual IPs.   ...
