Step-by-Step Guide to Install Zabbix 3.4.6 on CentOS 7 with MariaDB

1. Preparation

OS: CentOS 7.4 Zabbix version: 3.4.6 (released 2018‑01‑15) Database: MariaDB

Disable firewall: systemctl stop firewalld Prevent firewall from starting on boot: systemctl disable firewalld Disable SELinux temporarily: setenforce 0 Disable SELinux permanently:

sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config

After completing the preparation, reboot the system.

2. Install MariaDB

Overview: MariaDB is a community‑maintained fork of MySQL, fully compatible with MySQL APIs and command‑line tools, created to avoid potential closed‑source risks after Oracle's acquisition of MySQL.

Install MariaDB server via yum: yum -y install mariadb-server mariadb Start MariaDB and enable it to start on boot:

systemctl start mariadb && systemctl enable mariadb

3. Install Zabbix 3.4.6

Version highlights:

Install Zabbix server, web interface, and agent packages:

yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-agent zabbix-get zabbix-sender

Create the initial Zabbix database:

mysql -uroot
create database zabbix character set utf8 collate utf8_bin;
granted all privileges on zabbix.* to zabbix@localhost identified by 'zabbix';

zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix

Configure the Zabbix server to use the database (edit /etc/httpd/conf.d/zabbix.conf and set the timezone):

vim /etc/httpd/conf.d/zabbix.conf
php_value date.timezone Asia/Shanghai

Start Zabbix server, agent, and Apache, and enable them at boot:

systemctl start zabbix-server zabbix-agent httpd && systemctl enable zabbix-server zabbix-agent httpd
